How to Replace the Rear Wheel of an E-Bike

Need to replace the rear wheel on your FavoriteBikes e-bike? This guide walks you through the process step by step — from safely removing the old wheel to installing and aligning the new one. Watch the video below for a full visual walkthrough, or follow the written steps at your own pace.

Before You Begin — Safety & Preparation

⚠️ Safety First: Power off your bike completely before starting. Disconnect the motor cable from the rear wheel before removal to avoid damage to wiring.
  • Place the bike on a stable bike stand, or lay it on its non-drive side on a soft surface.
  • Gather your tools: 15mm wrench (for axle nuts), hex keys, and a clean cloth.
  • Note the routing of the motor cable and any brake cables before removing anything — take a photo if needed.

Step-by-Step Overview

  1. Disconnect the motor cable: Unplug the rear motor connector. This is usually a waterproof connector near the chainstay. Do not pull by the wire — press the release tab and disconnect gently.
  2. Release the brakes: Open the brake quick-release (if your model has one) or loosen the brake cable anchor bolt to give the wheel room to pass through the brake pads.
  3. Remove the axle nuts: Use a 15mm wrench to loosen and remove the nuts on both sides of the rear axle. Keep the washers in order.
  4. Remove the old wheel: Carefully slide the wheel out of the dropouts, guiding the chain off the cassette/freewheel. Set the old wheel aside.
  5. Install the new wheel: Place the new wheel into the dropouts. Thread the chain onto the smallest cog. Ensure the axle seats fully and evenly in both dropouts.
  6. Reconnect the motor cable: Plug the motor connector back in until it clicks. Make sure the cable is routed cleanly and is not pinched.
  7. Tighten the axle nuts: Hand-tighten first, then torque evenly on both sides. Do not over-tighten — this can damage the dropout.
  8. Re-engage brakes and check alignment: Adjust the brake pads if needed so they contact the rim/rotor evenly. Spin the wheel and confirm it runs true (no wobble).
  9. Test before riding: Power on the bike and take a short test ride at low speed to confirm the motor engages correctly and brakes function properly.
