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.

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.
