How To Pump The Tires In 4 Easy Steps

Electric bikes have become increasingly popular in recent years, providing a convenient and eco-friendly mode of transportation. However, like any bike, electric bikes require regular maintenance to keep them running smoothly and safely. One important aspect of e-bike maintenance is ensuring that the tires are properly inflated. In this blog, we will outline how to pump the tires on a C3strom Astro Pro class 3 E-bike in 4 easy steps. C3strom Astro Pro is one of the fastest E-bike, and for this kind of hyperbike, maintenance is rather important, in order to make the bringing out its full performance.

Step 1: Check the recommended tire pressure

Before pumping up your C3strom Astro Pro’s tires, it is important to check the recommended tire pressure. The recommended tire pressure can typically be found on the sidewall of the tire itself or in the owner’s manual. It is important to note that different types of tires require different amounts of pressure, so be sure to double-check the recommended pressure for your specific tire type.

For the C3strom Astro Pro, the recommended tire pressure is typically between 17.5-35 p.s.i. This pressure range is ideal for the class 3 bike’s electric motor, which can reach speeds of up to 28 mph. Keeping the tires properly inflated not only ensures a smoother and safer ride but also maximizes the bike’s performance and battery life.

Step 2: Prepare your pump

Once you have determined the recommended tire pressure for your C3strom Astro Pro, it’s time to prepare your pump. Make sure your pump is compatible with the valve type on your bike’s tires. If your pump is not compatible with your valve type, you may need to use an adapter to make it work.

Before attaching your pump to the valve, ensure that it is properly assembled and ready to use. Some pumps require specific attachments or settings, so it’s always a good idea to double-check the pump’s instructions to ensure that it’s ready to go.

Step 3: Attach the pump to the valve

With your pump prepared, it’s time to attach it to the valve on your C3strom Astro Pro’s tires. If you have Presta valves, you will need to unscrew the nut at the top of the valve to allow air to flow through. If you have Schrader valves, simply attach the pump nozzle to the valve and press down on the valve pin to release any trapped air.

It’s important to ensure that the pump nozzle is properly attached to the valve to prevent air from escaping while pumping. If the nozzle is loose, it may result in inaccurate tire pressure readings or an improperly inflated tire.

Step 4: Inflate the tire

With the pump attached to the valve, it’s time to inflate the tire to the recommended pressure. Begin by pumping air into the tire and monitoring the pressure with a tire gauge. If your pump has a built-in gauge, you can use that to monitor the pressure. Otherwise, use a separate tire gauge to ensure that the pressure is within the recommended range.

As you pump, pay attention to the resistance of the tire. When the tire starts to become difficult to pump, it is likely to be close to the recommended pressure. Once you have reached the recommended pressure, remove the pump nozzle from the valve and replace the valve cap.

Final Thoughts

Properly inflated tires are crucial for a smooth, safe, and efficient ride on your C3strom Astro Pro class 3 E-bike. By following these four easy steps, you can ensure that your bike’s tires are properly inflated and ready for your next ride. Remember to check the recommended tire pressure before pumping, ensure that your pump is properly prepared and attached to the valve, and monitor the pressure as you pump. With a properly inflated tire, you’ll enjoy a more comfortable and efficient ride, while also reducing the risk of punctures or damage to your tires.

It’s also important to check your bike’s tire pressure regularly, especially if you use it frequently or on long rides. Tires can lose pressure over time, so it’s a good idea to check them before each ride, or at least once a week if you use your e-bike regularly. A tire that is underinflated can result in poor handling, decreased range, and increased wear on your bike’s components, while an overinflated tire can reduce traction and increase the risk of punctures or damage to your tire.

In addition to proper tire inflation, there are other important aspects of e-bike maintenance to consider, such as cleaning and lubricating the drivetrain, checking and adjusting the brakes, and inspecting the bike for signs of wear and tear. By maintaining your e-bike regularly, you can prolong its lifespan, improve its performance, and ensure a safer and more enjoyable ride.


Proper tire inflation is an essential aspect of e-bike maintenance that should not be overlooked. By following these four easy steps, you can ensure that your C3strom Astro Pro class 3 E-bike’s tires are properly inflated and ready for your next ride. Remember to check the recommended tire pressure, prepare your pump, attach the pump to the valve, and inflate the tire to the recommended pressure. With properly inflated tires, you’ll enjoy a more comfortable, efficient, and safe ride on your e-bike. Don’t forget to also maintain other aspects of your e-bike, such as the drivetrain, brakes, and overall condition, to ensure its longevity and safety.

How to use the battery safely

The battery is one of the most frequently removed components when using an E-bike. There are quite a few issues in the daily use of the battery that deserve our attention. Maintain good battery use habits, which will help a lot with battery life and rider safety.


Please check device compatibility before charging

We recommend that all our riders use the official standard C3STROM charger (ASTRO/ASTRO PRO charger). This charger is a lithium-ion battery charger with an output voltage of 100-240V and is perfectly adapted to 52V ASTRO E-bike batteries. When there’s a situation where you have to use another charger to charge your battery, please check the output power of the charger carefully to confirm it is the same as the official charger.

However, we still do not recommend the long-term use of unofficial battery chargers to charge the battery, incompatible charging equipment will have a significant impact on the life of the battery, and there is also the possibility of battery damage due to incompatible equipment.


Safe charging procedure

Safe charging steps

When charging.

  • Plug the charger output into the socket
  • Connect the charger input to the AC power

To end charging.

  • Unplug the charger input from the AC power
  • Unplug the charger output from the socket


How to place the battery when charging

  • There should be no flammable or explosive items around the charger and battery.
  • The battery should be placed in a safe place where children cannot touch it.
  • The battery should be placed in a safe place that is ventilated and dry.


Charging abnormalities

Stop charging as soon as possible if any of the following abnormal conditions occur while the battery is charging.

  • Battery bulge
  • The battery emits a strange smell
  • Charging time exceeds the time limit and the green light is not yet on
  • The battery casing is damaged
  • Due to the different use scenarios, improper charging methods can cause the above problems, and if the power is not cut off in time, the battery may explode or catch fire.


Please do not charge in the open-air environment

Please do not charge the battery in the open air environment to avoid sudden rains that cause short-circuiting of the battery resulting in battery damage.


Charge the battery regularly

When you don’t use your E-bike for a long time, please charge the battery at least once a month to avoid battery power loss.

Regularly charging the battery for a short period can avoid damages caused by overcharging and transitional undercharging, and can effectively improve the service life of the battery.


Keep it at a certain temperature

It is recommended not to charge the battery at 7℉. This is because the C3STROM official battery has a low-temperature protection function. The normal temperature range for battery charging and discharging is 7℉~150℉. Above or below this temperature range, the battery may not be charged. Which is a new battery protection feature added by our technical team to protect the safety of our riders.

Also, when using the battery, when the temperature exceeds 150℉, the battery’s protection system will activate the over-temperature protection to cool down the battery to within 150℉.

When the outdoor temperature reaches 7℉, you can remove the battery and put it into a warmer and drier room for charging.


Storing the charger in a dry environment

Please keep the charger in a dry place and make an effort to keep rain and metal debris from getting inside. After a prolonged time of bumps, vibrations, and dampness, the charger will be easily destroyed if rain and metal particles penetrate.

How to Store Your Electric Bike in Winter

Many people have told us that the snow buildup and chilly temperatures make it hard to ride a bike in the winter. Naturally, we also hope that the chilly winter will end soon for the benefit of all C3 users. When not being used for a prolonged period of time in the winter, how can electric bicycles be stored properly?


Store the battery fully charged

Electric bicycles are more likely to remain parked for a long period in the winter because of the chilly temperatures, rain, and snow. In fact, proper battery storage is the most crucial factor. The battery of an electric bicycle will continue to use energy when it is not used for a while. The battery is said to be “self-discharging” in this circumstance. The idea behind this is that since the battery is still made of plates and acid, there will still be chemical and physical interactions. Long-term low-power and static usage of the battery increases the risk of damage, which slows down charging and prevents the battery from charging correctly. Remove the battery from the electric bike and keep it fully charged indoors if you won’t be using it for an extended length of time, especially in the winter when it will be cold outside.

For instance, the electric bicycle with C3 at this point has a battery capacity of 20Ah, and its energy consumption per hour for the battery board, self-discharge, and protection board is around 0.2–0.4mA. The basic battery provided by C3 may theoretically be fully charged. Although the battery has been completely charged and has been kept for more than a year, we nevertheless advise monitoring the battery level at least once every two months to prevent unusual events.


Pay attention to battery maintenance

We advise monitoring the battery state at least once every two weeks if the electric bike won’t be used for a while.

Maintenance strategy

1. To maintain the battery’s operating frequency, start the electric vehicle and attempt to drive a short distance in a sparsely populated field.

2. To verify the battery’s remaining power, turn on the battery power switch; pay attention to charging in time.

3. Wipe the battery’s outside structure gently if it has water mist or ice on it.

4. Charging maintenance, owing to the cold weather, charging in the winter will result in lower energy efficiency and longer charging times. Normal conditions dictate that the battery’s charging time will increase by 1-3 hours during the winter. When I don’t ride my electric bike for an extended period of time, I need to charge the battery completely at least once every half month to maintain battery health.


Avoid damp and rust

The outdoors will become quite humid in the winter because of prolonged exposure to snow and water mist. The electric bicycle’s flywheel, center shaft, chain, and shaft will all suffer harm if it is left in such an atmosphere for an extended period of time. The objective of this is to stop the parts of the bike from rusting. Brakes, brake handles, and other parts are extremely easy to rust. You may attempt to clean them with lubricating oil before storage. Therefore, we advise taking the electric bicycle’s battery out and storing it indoors while keeping the remaining components either indoors, outside with a cover over them, or in an underground parking garage.

How to ride safely in a light rain

Recent inquiries have focused on whether our C3STROM products can be ridden normally in light precipitation. Our response is that riding in light rain poses no difficulty. Due to increased road unpredictability, riding in the rain still poses several safety risks, so how can we avoid these risks and ride safely?


Slow down and avoid emergency braking

Even though C3STROM products are equipped with puncture-resistant 20″ x 4.25″ tires that provide a strong grip for daily road riding, when riding in the rain, the road is slick and it is easy for the vehicle to slide to the side when turning too quickly. Even though C3STROM products are equipped with four-piston hydraulic brakes, they cannot guarantee the same stopping power on wet roads as they do on dry roads. We sincerely hope that every user of the C3STROM can enjoy our products and travel safely. Therefore, it is crucial to reduce your speed and avoid emergency braking whenever possible.


Avoid getting the motor and controller wet on a wet road.

Although the motor and controller structure of C3STROM products have been tested for water resistance, prolonged or repeated exposure to water may still result in motor failure. Damage to the motor and controller frequently results in a series of malfunctions, including the horn not sounding, the turn signal not functioning, the brake light not functioning, and the controller not functioning properly. Observe the depth of the water prior to riding, and if necessary, dismount and push or take a detour.

And prolonged soaking will corrode metal components such as tooth plates, brake discs, chains, etc. Therefore, please dry the metal vehicle components thoroughly after riding in the rain.


Charging only after the battery has dried

When riding in the rain, it is inevitable that the bike will become wet. If the battery or charger is wet, a safety incident may occur. Even though the battery charging port of C3STROM products has a waterproof design, you should still check after each ride to ensure that the port, battery, and charger are not wet, and then dry them before charging.


Do not perform motor repairs in the rain

PAY ATTENTION! Please do not perform motor maintenance in the rain! When checking the circuit in the rain with two hands while standing next to the bike, there are conditions for electrocution to occur. It is comparable to touching the positive and negative poles with your hands, which poses the risk of electric shock. In the event of a malfunction, please disconnect the battery power as soon as possible. If repair is required, be sure to contact a professional.


The view on a rainy day is obstructed.

During riding on a rainy day, raindrops tend to accumulate on the lenses of the helmet, which is vitally important. A clear view can help us avoid many potential traffic accidents. In heavy rain and fog, the lighting function of a vehicle’s headlights will be reduced, so please avoid driving in such conditions.

Please feel free to send us a message if you have any issues or inquiries, and we will respond to you as soon as we can. We’d be overjoyed since we value our connections with our patrons and supporters.

What are moped-style electric bikes and how to choose one?

Moped-style electric bikes are designed to resemble a motorcycle, but with pedals and an electric motor. They have a small frame and appear light because the whole package often has quite a lot of negative space – the frame in this case is a mix of bike and motorbike. The main attraction of this type of bike is its ease of use and the fact that you don’t need a license for it as it is still considered to be an ebike.


What are moped-style electric bikes?

Moped-style electric bikes, also known as e-bikes, are becoming increasingly popular due to their many benefits. E-bikes are environmentally friendly, cost-effective, and convenient. They are also a good choice if you live a busy life and a car just not seems like an effective way.

There are many different types of e-bikes on the market, so it is important to do your research before purchasing one. The most important things to consider are the battery life, motor power, and top speed. You should also decide whether you want a pedal-assist or throttle-assist e-bike.

Battery life is an important consideration because you will need to recharge your e-bike after every few hours of use. Motor power is another important factor to consider because it will determine how fast your e-bike can go. Top speed is also an important consideration for safety reasons.

E-bikes can be a great investment for anyone looking for an alternative means of transportation. They are also a great way to stay active and get around if you live in a busy city or do not have access to a car.


The decision process

The decision process for choosing a moped-style electric bike can be broken down into a few key points. First, decide what type of riding you’ll be doing most often. Moped-style electric bikes like our C3STROM ASTRO is a great choice for commuting or running errands around town, it’s built for riding on city streets like classic rebels in old movies.

Next, consider your budget. Moped-style electric bikes can range in price from a few hundred dollars to over a thousand, so it’s important to have a firm understanding of how much you’re willing to spend before beginning your search. Under $3000 ASTRO offers exceptional functions and components.

Finally, think about what features are most important to you in an electric bike. Do you want one with a lot of horsepower? A long-range? By taking the time to consider your needs, you’ll be able to narrow down your options and choose the best moped-style electric bike for you.


Advantages of an electric bike

Electric bikes offer several advantages over traditional bicycles. Perhaps the most significant advantage is that they can make biking easier and more enjoyable for people of all ages and abilities.

For example, electric bikes can provide a much-needed boost when climbing hills or riding into headwinds. They also make it possible to bike for longer distances without tiring oneself out. Additionally, electric bikes are environmentally friendly since they do not produce emissions as gas-powered vehicles do.

Another advantage of electric bikes is that they tend to be very low maintenance. There are no tune-ups or oil changes required as there would be with a gas-powered bike. Electric bikes also tend to be very reliable since there are fewer moving parts than on a traditional bicycle.

Finally, electric bikes can be great fun to ride! They often come equipped with cool features like LED lights and digital displays that add an element of excitement to the biking experience.


Choosing the right type of bike for you – Ride C3STROM  ASTRO 

Considering the above points ASTROs checks everything in the list of advantages. It’s also fully feature-packed. Light, good looking, and what’s more it has 750 Watt motor with 80Nm of torque, which means it rides absolutely great in the city and tackles hills with ease. Considering its price point is easily under $3000 it’s an amazing choice for what it offers.

When riding a moped-style ebike the battery life is extra important and the ASTRO actually has a 1040Wh battery which is huge in this price class. Unlike normal ebike, you want to ride moped-bikes quite a lot with throttle just like you’d do with a normal motorbike. The large battery capacity of ASTRO means that you can ride it up to 78 miles by just using the throttle if you also pedal your range extends considerably but for a day’s ride 78 miles should be easily enough!

The motor and battery are of quality too as the Bafang motor is well-known in the e-bike industry for its great value and performance. To make sure the battery doesn’t die too early either it uses Samsung cells.



Moped-style electric bikes are a great option for those looking for an alternative to traditional bicycles. They offer many of the same benefits as regular bikes, but with the added bonus of being electric-powered. When choosing a moped-style electric bike, it’s important to consider your needs and budget. Once you’ve found the perfect bike for you, enjoy cruising around town or taking on new adventures!

How to set the correct tire pressure

As the only part of the bike to directly contact the ground, the tires need to be treated with care. It’s particularly important to know how to set the tire pressure accordingly for certain types of terrain and road conditions, so that the tire can give optimal performance. This article will tell you all you need to know about tire pressure.

Before getting started, let’s just have a look at what effect having tire pressure that is too low, too high and just right can have on your cycling.


Too Low

Tire pressure that is too low will increase the risk of tire damage when coming into contact with sharp objects (e.g., gravel and tree roots). There is also a high probability of getting a flat tire or even the ground hitting the rim. What’s more, too low tire pressure will affect the elasticity of the tire, resulting in unstable feedback at high speed. In addition, when facing corners, having tire pressure that is too low will result in insufficient support and control of the bike. In fact, the tire can even come off the rim.



Too High

Having tire pressure that is too high will reduce the area of contact between the tire and the ground. This causes several problems, including reducing traction, transmitting impact to the rider (causing vibrating or rattling in the hands) and causing discomfort.



Just right

Having the correct tire pressure will give a balanced traction and rolling resistance, which will greatly improve the riding experience. The tire can have a good amount of traction without dragging along the floor. Additionally, the chance of getting a flat tire or the tire coming off the rim is very low.

So, when the tire pressure is too low, increasing the tire pressure can help to support the tire wall, to provide better stability and protection to the rim. Likewise, decreasing tire pressure can increase the contact area between the tire and the ground, thereby improving the traction, which can allow the rider to more easily deal with uneven road surfaces. Simultaneously, this also allows the tire to absorb some of the vibration, which greatly improves comfort.



Factors that affect tire pressure 

One should consider the following:

  1. Maximum tire pressure that the rim and the tire can withstand: take the lower value of the two as the limit value, although generally speaking, in normal use it is very rare for this limit to ever be reached.


2. Carrying load: To calculate this, one only really needs to take into consideration the weight of the rider. The greater the load on the wheel, the higher the tire pressure required.


3. Cycling terrain: This factor requires the rider to adjust the tire pressure before each ride. You need to consider the wetness of the road; a wetter road will require more traction and thus greater tire pressure. When facing more bumpy roads, the tire will need to have slightly less pressure in order to reduce the vibrations transmitted to the rider. When facing a more gravelly road, you’ll need to increase the tire pressure to avoid tire damage.


4. The quality of the external tire technology: if the external tire has excellent puncture prevention capacity, you may consider reducing the tire pressure a little.


5. Tire volume: A tire with larger volume can have a lower tire pressure.


6. Whether or not it is a vacuum tire: The chance of puncturing a vacuum tire is very low, so it can have much lower tire pressure.


7. Rim structure: If the bike uses a hookless vacuum rim, then the tire pressure used by drivers can be lower.


8. Riding ability level and style: Drivers with a more aggressive cycling style need to increase their tire pressure appropriately because they need to have very good feedback and reliability from their tires. Novice riders can use tire pressure that is a little higher, because these riders often have a higher probability of damaging their tires due to improper use of the bike.


How to set the suitable tire pressure

Step 1: determine the tire pressure standard. Bicycle tire pressure due to the different brand, the tire pressure regulation range will also vary. Most tires will be marked with the minimum and maximum tire pressure range. The tire pressure for the C3STROM ASTRO is between 120-240psi or 1.2-2.4 ba


Step 2: set the pressure according to the terrain. Take the bike out for an actual ride and adjust the tire pressure.

First, choose a section of road that you will ride and start with a higher tire pressure (we take a higher tire pressure as the starting value of adjustment to facilitate later adjustment).

Next, take a ride. Pay attention to the cycling experience, and the tire feedback. The main things to consider are the bumpiness when riding, the amount of support given, the impact on the ring and the traction.

Reduce the tire pressure and ride again; it should feel different from last time. The front and rear wheels are reduced by about 3 to 5 psi per time. Then the process is constantly repeated, until the tire pressure is appropriate.

As the tire pressure drops, you will feel improved traction.

But as the tire pressure decreases, you may gradually feel that the feedback of the tire becomes very unstable when riding at high speed, and you can even feel the direct impact between the ring and the obstacle.

At this time, the tire pressure is a little too low, so you should then appropriately increase tire pressure a little bit; increase by 2~3psi each time, until this feeling disappears. Find this critical point where the tire pressure is as close as possible to your ideal tire pressure.

Step 3: adjust the balance before and after the adjustment. When cycling, more center of gravity will fall on the rear wheel, so the tire pressure of the front wheel can be a little lower. Due to the original value of tire pressure, the tire pressure of the front and rear wheels is relatively balanced. The front wheels can be fine-tuned to achieve an optimal balance of traction and stability.

Such a fine-tuned set-up, although looking a little cumbersome to achieve, will make your ride more comfortable, and the tires will work far better. But it is important to note that this is  just a very general, basic guide. Close fine-tuning is still required in the face of different terrain.

CHAPTER 1 How Does an Electric Bike Work?

What Is an Electric Bike?

The first thing that comes to mind when thinking about electric bikes is scooters or motorcycles. Still, in terms of shape, it is not much different from a regular bicycle, with the addition of some electrical parts (motors, batteries, controllers, meters, etc.) to a bike to turn it into an electric bike.

How Do Electric Bikes Work?

The controller employs the pedal-assist system or the throttle signal to enable the motor to convert the electric energy stored in the battery into kinetic energy, which is then used to drive the wheelset to rotate via electromagnetic induction.

What does W&Ah mean?

The power of the motor is represented by the W; the larger the W, the greater the power. The capacity of the battery is denoted by the letter Ah.

When compared to a transportation horse, the weight of our common carriage horses can carry is vastly different from the weight of goods that a Shire horse can carry, but this also means that the Shire horses will consume more feed. This is also true for the motor system. Furthermore, a more powerful motor will consume more power, so a larger W motor power requires a larger capacity battery.


CHAPTER 2 Different Types of Electric Bikes

What Are the Different Types of E-Bikes?

Are you perplexed when you see each brand’s product categories? Depending on the circumstances, the E-bike can be classified into several types. If we divide it by usage scenario, for example, it can be divided into E-city, E-fold, E-cargo, and so on. When it comes to performance, it can be classified as E-road, E-MTB, or E-gravel, among other things.

What Are the Different Classes of E-Bikes?

Class 1 E-bike – Pedal-assisted only electric bike.

Speed limited to 20mph.

Class 2 E-bike – Throttle E-bike with an optional pedal-assist

Speed limited to 20mph

Class 3 E-bike – Pedal-assist & optional throttle.

Speed limited to 28mph.

Class 4 E-bike – Unlimited power & speed electric bikes with pedals.

Any E-bike which has a higher assisted speed of 28mph or power over 750W is considered as a class 4 E-bike.

According to National Conference of State Legislatures: State Electric Bicycle Laws. 

Where Is the Motor on an E-Bike?

Hub motors and mid-drive motors are the two types of electric bicycle motors; the hub motor is usually integrated into the rear or front wheels. The mid-drive motor is located in the middle of the bike, between the bottom bracket pedals.

Where Is the Battery on an E-Bike?

Many factors influence the location of the battery, including the bike model, battery size, and so on. The down tube is the most common location for the battery. The down tube battery not only does not detract from the appearance, but it also maintains a good balance.


CHAPTER 3 Where Will You Be Riding?

Using an Electric Bike to Commute

The use of an E-bike for commuting has become popular in recent years because it not only saves time, but also allows you to exercise while commuting to work, and it is also environmentally friendly.

Electric Bike Regulations

The Consumer Product Safety Commission regulates electric bicycles for product safety reasons. This means that the federal government only regulates the condition of a for-sale electric bicycle, not how it is used. An electric bicycle is defined by federal law as a low-speed electric bicycle with fully operable pedals and an electric motor of fewer than 750 watts that do not exceed 20 mph when powered solely by the motor. The maximum speed for travel using a combination of human power and a motor is not specified by federal law.

You should check with your state to see which E-bike laws apply to you. State traffic laws differ and govern how electric bicycles can be used in each state. W-bikes are defined in most states’ traffic laws, but some do not. Furthermore, some states have laws that only apply to electric bicycles. Some states, for example, require a license to ride an electric bicycle. Other states have laws that apply to electric bicycles in the same way that they do to traditional bicycles.


CHAPTER 4 Pedal Assist or Throttle Controls?

What’s the Difference Between a Pedal Assist Electric Bike and a Throttle Electric Bike?

A pedal-assist e-bike only assists when the pedals are pushed and the motor’s electronic system is engaged. You can select the level of assistance you want with pedal assist. Most bikes have three to five assist levels ranging from low to high. When you start the E-bike, the PA system will automatically turn on, and the pedal assist will kick in as you pedal.

If you want to get a workout, choose a low setting, and you’ll get a little pedal-assistance, requiring you to pedal harder. A high setting, on the other hand, will get you where you need to go faster and with less effort than a low setting.

A throttle e-bike propels the vehicle forward without the need for pedaling.

How Does an Electric Bike Throttle Work?

An electric bicycle’s throttle is very similar to a motorcycle’s throttle. It is typically mounted on the handlebars. For example, when you twist the throttle, the bike will begin to accelerate and will come to a complete stop when you let go of the throttle.

Why Choose a Throttle?

Throttle can be a great addition to your e-bike riding experience. Instead of pedaling, a throttle provides a boost on demand, which can be useful. A throttle gives you more power and control, making biking less exhausting, especially for those who haven’t ridden a bike in a long time. The throttle will be there for you as a good friend, and it’s always nice to have another option.

Do All Electric Bikes Have a Throttle?

Not all electric bicycles on the market, according to laws and regulations, have a pedal-assist system and a throttle. However, as a brand that specializes in the C3 classes, all of our current and future models will include both a pedal-assist system and a throttle, providing our customers with even better experiences.

Speed sensor VS Torque sensor?

A torque sensor detects how hard the rider is pedaling; the harder you pedal, the more assistance; a speed sensor detects how fast the rider is pedaling; the faster you pedal, the more assistance.

Based on your requirements, you can select the best type for you.


CHAPTER 5 How Far Will You Be Riding?

Electric Bike Battery Types

Lead-acid Electric Bike Batteries:

Lead-acid batteries are the most expensive and difficult to recycle, have a lower power output, and are the heaviest type of E-bike battery.

Nickel-cadmium Batteries (NiCd):

Lead-acid batteries have less capacity per pound than nickel-cadmium (NiCd) batteries. Nickel-cadmium, on the other hand, is expensive, and cadmium is a hazardous contaminant that is difficult to recycle.

Nickel-metal Hydride Batteries (NiMh):

Nickel-metal hydride batteries have a short lifespan. Even when used infrequently, NiMh batteries produce a lot of heat and are difficult to keep in good working order.

Lithium-ion Batteries:

Lithium-ion batteries have the highest capacity of any existing battery type. They are not memorable, which makes them more durable and long-lasting.

In conclusion, Lithium-ion batteries seems to be the best option for E-bike.

How long does the battery last on a single charge?

The battery’s lifespan is determined by a variety of factors, including battery power, whether you use pedal-assist or steering, and even road and weather conditions. However, it can typically travel 25 to 70 miles on a single charge.

The battery’s entire life is determined by the type of battery. Lead-acid batteries typically have a charge cycle life of 200 to 300, whereas lithium batteries have a charge cycle life of 500 to 1,000.

How Much Does an Electric Bike Battery Weigh?

The weight of a battery is determined by its size and capacity. A 48V standard battery with 52 cells, for example, weighs slightly more than 7 pounds, whereas a 52V battery with 70 cells weighs 10.6 pounds.

What Is the Longest Range for an Electric Bike?

Our C3STROM-X1 with 52V20Ah 21700 battery cells use throttle only, the most extended range is 32miles.

How to calculate the charging time?

You could use the following formula to calculate the charging time:

Use the battery’s AH and the charger’s A (e.g., 52V20Ah battery with 58.8V4A charger, so 20Ah4Ah=5h, or about 5 hours)

This way, you can get an idea of how long it will take to charge.


CHAPTER 6 Safety

E-bike Battery Tips

  • Charge your brand-new battery pack for 12 hours.
  • Temperature extremes should be avoided.
  • Before charging, turn off the motor and the battery.
  • Don’t let your E-bike battery run down.
  • Avoid overcharging the battery.
  • Even if it is not in use, recharge your battery at least once a month.
  • Do not leave the charger plugged in all the time.

E-bike maintenance

The key to extending the life of your E-bike is to keep it clean and dry, but here’s some simple advice:

  • Before each ride, check your tire pressure.
  • Check and adjust the brakes on a regular basis.
  • Keep the battery completely dry at all times.
  • Clean your E-bike on a regular basis. Find a reputable bike shop and take your E-bike there once a year for inspection.

Why need a derailleur set while it is an electric bike?

This question is for when you’re riding your E-bike with the Pedal Assistance (PA) system.

An e-bike is a bike that has electronic components to make your ride easier, but it’s still a bike if you don’t use the throttle at all. Adding a derailleur set may allow you to have a better riding experience on different terrains.

How to Make Your E-bike Go Further (E2)

Continued from the previous article The Secret of Ultra-Long Life Span – How to Make Your E-Bike Go Further (E1)

Many people wonder how far they can ride an electric-assist bike, but businesses are often unable to provide an accurate answer because there are so many variables. So, how can you ride further under the given configuration conditions? Here is a list of general tips for your reference, following the previous article on The Secret of Ultra-Long Life Span – How to Make Your E-bike Go Further (E1).

  1. Tires

Lightweight tires may appear appealing and logical, but they should not be chosen. This is a “false economy” product that will negatively impact your ride. Because of the extra weight, you will use the sidewall more on an electric bike, and because the rear wheel is difficult to get off the ground, it will take more force when hitting rocks and roots.

Higher tire pressure and heavy-duty tires are required to avoid frequent sidewall punctures. While weight is one of the influencing factors for range longevity, durability and size must also be considered.

  1. Brakes

Don’t skimp on efficient brakes, just like you wouldn’t on tires. Upgrade to four-piston brakes if possible. You’ll improve your power by braking less frequently and only when necessary. And a thousand reminders to check your brake pads for wear frequently before, during, and after a ride, and to always keep spare pads on hand.

  1. Chains and Guide Pulleys

A clean, well-lubricated, and free-rolling chain experiences far less resistance than a dirty, poorly maintained chain. And, especially when shifting uphill, the motor can put a lot of strain on the drive train. So, as detailed in the How to Maintain Your Electric Bike article on how to clean your chain, check for wear and tear regularly and keep it well lubricated.

  1. Turning

Leaning your e-bike into a turn requires more muscle power, but once your balance and center of gravity are correct, the weight of the bike will maintain consistent traction. To get a longer ride, avoid bouncing between turns and instead take a more cautious approach. Try pedaling around corners while keeping the motor running on slight uphill or flat gentle turns. If you think you’re going too fast, slow down but keep the cranks turning. We discovered that this continuous and calmer motion consumes less energy than braking and then skidding.

  1. Climbing a hill

Remember to shift into neutral before pressing the power button. Again, high cadence is essential. Find a comfortable seat that allows you to keep your weight on the rear wheel. An e-front bike’s wheel is less likely to lift, allowing you to sit up straighter and concentrate on traction. Shift down through the flywheel to keep the motor running at a high cadence. Keep your gaze on the horizon; don’t be concerned about a slick course; instead, concentrate on maintaining power.

  1. Downhill

Don’t forget to set the downhill mode to “energy saving.” Even if you believe it makes no difference because you won’t be pedaling much at this time. But it works, and over the course of a 30-40km ride, it all adds up. Don’t think about accelerating sharply once the speed exceeds the speed limiter (25kph/15.5mph). Instead, keep a steady cadence and maintain your impulse in the turns. Rather than pedaling, accelerate, as the bike will not accelerate without this assistance. Don’t be concerned about roots and rocks; you won’t be able to jump up like a normal bike, and you’ll take them out anyway. Consider going bigger and wider!

How to Make Your E-bike Go Further (E1)

E-bike can usually be ridden more frequently than regular bikes, but who wouldn’t want to have more longevity? So, what are the requirements for getting the most out of an electric-assist battery and motor?

Even the best electric-assist mountain bikes can cause headaches due to range if ridden in an inappropriate manner or set up incorrectly. This is the time to pay attention to the ten super helpful tips that will extend the range of your electric-assist bike ride!

  1. Power mode

Please use the battery’s “smart” mode. For example, use Bosch’s eMTB mode, or launch the bicycle motor manufacturer’s app on your phone to see how the motor is configured. Simply reduce the power levels or choose one of the preset values. Shimano’s “Explorer” mode, for example, maybe better for you than its default “Dynamic” preset. Many Shimano STEPS users, for example, now prefer to stay in “Eco” mode for 95 percent of the stroke and only use the low-power “Boost” mode for the remaining 5% of the stroke. Bypass Trail mode entirely. It’s also critical to keep your e-bike’s firmware in good working order by using the most recent software. This is typically accomplished through the use of Bluetooth on your phone, so it should be fairly simple, right?

For example, the Bafang mid-motor system typically has 5 gears for riders to choose from; however, except for the long and difficult steep slopes that inevitably necessitate strong power mode, 2-3 gears can handle more than 70% of road conditions; While the TENTEN power mid-motor system equipped by BESTRONG Travel has different modes of ECO, NORMAL, SPORT, and TURBO, it also has the i-SPORT automatic mode, which will automatically adjust the power output based on the current load. Furthermore, there is an i-SPORT automatic mode that will automatically adjust the output power based on the current state, and selecting the right power mode during the ride can help you save a lot of electricity.

  1. Shifting gears

This is a common mistake made by e-bike owners, namely ignoring the transmission. When you are unable to pedal, do not simply turn the turnbuckle; instead, apply pressure to the motor and battery. Adjust your gear ratios to make your e-bike last longer and ride farther; after all, it is still primarily a human-powered bike.

  1. Pedaling frequency

Any mechanic at a bike shop will tell you that the most serious issue that some electric-assist cyclists face is an addiction to pedaling frequency. This not only consumes power faster (causing customers to complain about not getting the advertised mileage), but it also drains the powertrain faster than it’s worth.

To keep the motor running at full power, you must pedal rather than skid. Pedal at a speed of 70 to 90 RPM. You’ll get the most assistance if you keep turning the crank. When the pedaling frequency falls, the motor slows down, which is especially inconvenient on steep climbs. Because electric-assist bikes benefit from a wide range of 1x drivetrains, you’ll need to change gears frequently to optimize your pedaling frequency.
