Hub Motor Kit — 30-Minute Install

What You Need

Step 1: Remove Old Wheel (5 min)

Open quick-release or loosen axle nuts. Remove wheel. If rear: first shift to smallest sprocket, then drop chain off. Keep your cassette — you'll swap it to the motor wheel.

Step 2: Swap Cassette (5 min)

Remove cassette from old wheel using cassette tool + chain whip (or take it to a shop for £5). Install on motor wheel freewheel body. Hand-tighten, then use cassette tool to snug it down.

Step 3: Swap Tyre (10 min)

Remove tyre and tube from old wheel using tyre levers. Mount on motor wheel. Inflate to recommended PSI (check tyre sidewall).

Step 4: Install Motor Wheel (5 min)

For rear: thread chain over smallest sprocket, drop axle into dropouts. The motor cable exits from the non-drive side — route it upward along the chainstay. Close quick-release firmly or torque axle nuts to 25Nm.

Step 5: Mount Controller (3 min)

Use velcro straps or zip ties to mount the controller under the down tube or behind the seat tube. The controller runs hot — leave airspace around it.

Step 6: Route and Connect (5 min)

Route the motor cable along the frame. Run throttle and display cables to the handlebar. All connectors are colour-coded — they only fit their matching plug. Zip tie every 10cm.

Step 7: Test

Power on. Check all connections seated. Test throttle response with wheel off ground. Test PAS by pedalling slowly. Check brakes — cutoff sensors should kill motor immediately.
