Battery dies fast or range droppedTroubleshootingYour e-bike used to go further on a charge. How to tell normal wear and riding conditions from a battery or charger problem.
Battery won't chargeTroubleshootingThe charger light doesn't change or the battery won't go up. Safe checks on the charger, the outlet and the port, and when to stop.
Clicking, grinding or squeaking noisesTroubleshootingWhere e-bike noises usually come from: the chain and gears, the brakes, loose bolts, the cranks and bearings, or the motor.
Display blank, flickering or frozenTroubleshootingThe handlebar display won't show anything, flickers or freezes. Usually a plug, the battery, water or the display itself.
Display works but no pedal assistTroubleshootingThe display turns on, but the motor doesn't help when you pedal. Check the assist level, the speed sensor and the brake cut-offs.
E-bike error codes: what they mean and what to try firstTroubleshootingYour e-bike display shows an error code. Here's how to read it, the safe things to try yourself, and where to find your system's official code list.
E-bike or scooter won't turn onTroubleshootingNothing happens when you press the power button. Work through the battery, the key and the plugs before assuming the worst.
Motor cuts out or power comes and goesTroubleshootingThe motor stops helping on and off, over bumps or on hills. Usually a loose connection, a brake sensor, heat or a tired battery.
