- Removing the rear wheel, whether for repairs, replacing a tire or inner-tube, this needs to be handled correctly by someone with bike mechanic experience.
- When the rear wheel is removed, it can be detrimental to lay it flat on the axle where the motor cable is exiting as this can damage the cable and cause the motor to lose function completely which would not be covered under warranty.
- When re-installing your rear wheel, make sure it is fully seated in the drop outs and stays in place as you tighten the axle nuts. This is critical for safety.
- Once re-installed, please be sure to install a new zip-tie and verify your motor cable is routed properly to avoid damage or premature failure.
- If you decide to turn your bike upside down. Please be mindful of your display, brake levers, throttle, and any other accessories. Often placing a book under each handlebar grip will provide clearance.
- If you have hydraulic brakes and you turn the bike upside down, avoid squeezing the brake lever. This can introduce an air bubble into the brake line or caliper. Often when the bike is turn upside right again and the wheels (rotors) are installed, if you pump the brakes it will resolve the issue. If it does not, you may need to bleed your brakes.
- Cut the ziptie that holds the motor cable to the frame. Take care not to cut the motor cable.
- Loosen the 19mm axle nuts on either side of the frame.
- Lift the bike frame off the wheel. Many times this is easier than turning the bike over. However it may require a helper to remove it carefully.
- To reinstall wheel, ensure the torque spacers are on the inside of the frame and line up with the frame dropouts. This is critical for correct wheel fit and safety.
- Ensure the axle cutout is facing forward (see image below video). By doing this it prevents excess strain on the motor cable and damage.
- Place the motor cable and cassette between the two hanging chains and lower the bike frame on to the wheel. When doing this keep the axle orientation and spacer configuration in mind.
- Tighten axle nuts to 30nm.
- Plug in motor cable paying attention to the orientation. Line up the two arrows on the connector and do not bend any pins when reinstalling. Ziptie this cable back down when installed.
