What you need
| Tool | Notes |
|---|---|
| Socket set | Axle nuts and mounting hardware |
| Side cutters | Cable ties — you will cut some |
| Pen and phone camera | Photograph every connector before you unplug it |
⚠ Warranty note. Opening a motor voids the warranty on that part. Removal for a warranty replacement should follow CEMOTO support's instructions. See Warranty Claims.
Steps
- Power the bike off and let it stand.
- Support the bike with the wheel clear of the ground.
- Photograph the wiring at the motor before touching anything — phase order and connector orientation are easy to forget.
- Release the chain / belt tension and move it clear of the sprocket.
- Disconnect the three phase wires and the hall sensor plug. Pull connector bodies, never the wires.
- Remove the axle nuts and note the position of any spacers or torque washers.
- Lower the wheel out of the frame. It is heavy — support it as it comes free.
- Inspect before you go further: phase wire chafing, hall plug pin condition, bearing play, and any sign of water ingress at the cable entry.
While the motor is out
| Check | Why |
|---|---|
| Bearing play | Spin the wheel and feel for roughness or lateral movement |
| Cable entry | Water ingress here causes intermittent faults for months |
| Sprocket wear | Far easier to replace now than after refitting |
| Brake disc condition | Check for warping or scoring while it is off the bike |
