Hi all, I have a problem with an e-bike bought on Amazon, something cheap Varun brand (most likely Chinese) with a Keydisp 286 the problem is after I drive it for some time and let go of the throttle, the engine does not stop, it continues to go as if it were on automatic pilot, for example if I drive for 2-3 minutes at a speed of 30 km per hour and let go of the throttle, it continues to go at the same speed both uphill and downhill. How do I adjust this? Is there a problem with the engine? Throttle? or any setting from the display?
