E-Bike Service
Motor & Electrical Diagnostics
When an e-bike won't power on, cuts out, or throws an error, it's almost always electrical. I diagnose hub and mid-drive systems methodically — then explain the fault in plain language before any work starts.
What's included
- No-power and intermittent-power diagnosis
- Error-code reading and interpretation
- Controller and display testing
- Wiring harness and connector inspection
- PAS, torque and speed-sensor testing
- Motor testing and replacement
- Coordinating warranty work with your brand where it applies
Signs you need this
- Bike won't turn on at all
- Power cuts out under load or over bumps
- An error code on the display
- No pedal assist, or assist in only some modes
- Unusual motor noise or vibration
What does it cost?
Every e-bike is different, so I quote it honestly up front — no surprises. Call or text and I'll give you a straight answer.
