    Needs more information - make/model of the controller would be a minimum. Unfortunately there is not a lot of experience on this SE with EBikes so we will probably struggle to answer even a well formed question.

  • Consider that the throttle doesn't work like you expect. Its not a "valve" for power where bypassing would make any difference Instead, it will be signalling the computer/controller to adjust the widths of PWM in the three separate power wires. (yes it will be a 3 phase AC motor)

Id check out all the connections firstlt then id check for any breaks in the wiring as with it being a foldup bike ive heard of the wiring being caught/streched when folding down etc it could be a simple cause as this if not it almost definitley looks like a failing on the throttle mechanism to me


the wiring is damaged or your brake system is stuck. Take it out to the repair shop

    Surely a stuck brake system wouldn't produce the quoted symptoms. Walking mode wouldn't function properly for example.

  • I agree with chenmunka about the brake system being stuck surely the other modes would be compromised.
