Hiboy guides
- Hiboy S2, S2 Pro and KS4: display to controller communication error (E3, or E1 on the S2 Lite)TroubleshootingHiboy lists E3 as a display to controller communication problem on the S2 family and KS4, and E1 on the S2 Lite. Check the cable through the stem, then replace parts in Hiboy's order: cable, display, controller.
- Hiboy S2, S2 Pro and KS4: E5 low voltage error or the battery won't chargeTroubleshootingHiboy lists E5 as low voltage protection on the S2 family, KS4 and S2 Lite. Charge fully with a working charger first; if E5 stays after a full charge, Hiboy's fix is a new battery, a shop job.
- Hiboy S2, S2 Pro and KS4: throttle error on the display (E2, or E7 on the S2 Lite)TroubleshootingHiboy lists E2 as a throttle error on the S2 family and KS4, and E7 as the throttle error on the S2 Lite. Rule out a stuck lever and an applied brake, then replace the throttle, a plug-in Hiboy part.

Troubleshooting that applies to most models
- 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.
