What causes this issue?

This issue is normally caused by an impact or accident, however it can also occur as part of normal wear and tear over time, if the spokes become loose in the wheel.

How do I know I have this issue?

You will experience a 'wobbly' wheel when riding. You can recreate this by turning the bike upside down and spinning the wheels.

Note that a very slightly wobbly wheel (e.g. within 1mm) is considered within 'normal' wheel behaviour and does not constitute a safety risk. You can of course still have this looked at by any bike shop if you like.

Is this issue covered by warranty?

What tools are needed?

    • Tutorial on how to remove the rear wheel

    • On Cowboy Cruiser/ST/Classic, Cowboy 4/ST the tension of the spokes is different on each side of the rear wheel (due to the integration of the torque sensor in the motor hub). You'll feel that the spokes feel tighter on one side then on the other, this is perfectly normal. Make sure you don't over-tighten the spokes on one side (this could damage the rim) or don't leave the spokes too loose on the other side.

    • It can happen that the spokes on the loose side become very loose (to the point where you can turn the nipple by hand). If that's the case, start by tightening all spokes with little to no tension, then true the wheel as explained in the video above.

    • We use disc brakes rather than rim brakes - This provides us with a slightly larger margin of error when truing the wheel. Any left-right movement of a few millimeters won't affect the bike's functionality in any way.
