If your ebike's acting up, the odds are 60% it's the battery, 25% the motor/controller, and 15% accessories or wiring. This site walks you through each in that order.

Step 1 — Diagnose where it's failing

Ebike problems cluster into categories. Figure out which category first:

🔴 Battery issues

Won't charge, range dropping, fault codes. 60% of problems.

🟠 Motor / drive

Cuts out mid-ride, throttle dead, pedal assist won't engage.

🟡 Controller / display

Error codes, blank display, communication faults.

🔵 Accessories

Lights dead, lock stuck, bag problems. Not mechanical-critical but frustrating.

Step 2 — Read the fix flow

Every troubleshooting page uses the same structure:

The exact problem in plain English
The 2–4 most likely causes in frequency order
A step-by-step fix flow, simplest first
Brand-specific tips for Rad Power, Aventon, Lectric, Heybike
Product picks if the fix requires gear
FAQ

Stop at the step that solves it.

Step 3 — If nothing works, it's wiring or a dealer job

Some ebike issues need the manufacturer's warranty or a local shop:

Motor cut-out with no error code — could be internal motor damage
Controller error codes — some codes indicate factory defect
Battery BMS faults in warranty period — always contact manufacturer first
