How will the ASTRO PRO be delivered to me and what assembly is required?

A: The C3STROM ASTRO PRO will be delivered 90% already assembled, securely packaged in a box which includes the tools and instructions for assembly, so it only requires a final few steps to be completely assembled. There are instructions provided in the package to complete the assembly, as well as an online video to help you with installing the bike. If you don’t have much experience with ebikes and are unsure about the process even after reading the instructions and watching the video, then we recommend you to ask your local bike shop for help.

Do C3STROM offer any accessories?

A: Yes, we offer several optional accessories on our website, such as a rear rack, a folding lock, and a phone mount. We will also be launching other new extra equipment in the future.
