When Does Your Electric Bike Need Maintenance? 3 Warning Signs You Can’t Ignore

Owning an electric bike comes with proper care and maintenance. Here are 3 key signs that indicate your e-bike needs servicing:

Loud noise, slow speed under load, unable to restart after stopping

This could mean the motor is missing phases. Most modern controllers have smart design to avoid jittery restarts when phases are missing. The cause may be damaged Hall sensors in the motor or internal wiring issues in the controller. Check connections first, then replace the controller if Hall sensors are fine.

Wheels won’t spin with power on, difficult to push, clunking noises

This likely points to short circuit due to loose motor wire contacts. Unplug the 3 main phase wires of the motor – if pushing becomes easier, the controller is faulty and needs replacement. If still difficult to push, the motor windings may be shorted and burnt.

Intermittent controller performance

Unstable controller operation may stem from: parameter drift under extreme temps, overheating from high designed power, or loose contacts.

Caring for an Electric three-wheel bike requires regularly checking connections and performance of key components. Fix or replace damaged parts as soon as issues arise to ensure smooth rides.
