2021 or 2023 Foldaway?

VelectriX changed motors between years: the 2021 Foldaway uses a Dapu motor and the 2023 bike uses the VelectriX FX1. Knowing which motor you have tells you which controller to order.

Fit and compatibility

Suits the 2021 VelectriX Foldaway with the Dapu motor only. 2023 Foldaway bikes with the FX1 motor take VXAUS10605. Check the model number on your existing controller, or ask Tune.

Tune can fit the controller and check it with the motor and display.
