Frequently Asked Questions

Q. Will these fit my motor system?

A. Check if your motor is listed in the product specification, or search using the by system menu.
If you can not find your motor system contact Lekkie so we can help.


Q. Why should I choose a long or a short crank length?

A. In general if you are a smaller person you would have shorter crank lengths. For E-bikes shorter cranks can also increase ground clearance and enable higher pedal cadences.
You generally do not need the increased leverage a long crank provides with e-bikes.
