Frequently Asked Questions

Firstly, a 52v 2600w front motor system is installed on the front fork instead of the bicycle's front wheel. And its dropouts are 100mm. So please confirm your front fork dropouts is 100mm. Please click Dropouts and view the video of the Dropouts measurement.

Secondly, please choose the wheel size, we have 20" 26" 27.5" 28" 29" 700C wheels. If you are not sure which wheel size fits your bicycle, please click the wheel size to check how to confirm your bicycle wheel size.
