Troubleshooting: Drive Wheel Fell Off

Background Information

The hub nuts on the drive wheels are factory-treated with a low-strength threadlocker to facilitate easier maintenance and disassembly later.
However, under certain conditions—including during transportation—the nuts may gradually loosen over time.

If you find that a drive wheel has fallen off during use, please follow the steps below:

Steps to Take

1. Check for Other Damage Besides the Wheel Falling Off
   Carefully inspect the drive wheel and surrounding parts for any additional damage.

   • If you find other damage, please take photos and send them to us so we can arrange after-sales support.

   • If there is no other damage, please proceed to the next step.

2. Maintenance and Re-tightening the Nut
   Please refer to our Drive Wheel Regular Maintenance Guide.
   Follow the guide to apply threadlocker (recommended: LOCTITE 243 or equivalent), re-tighten the hub nut, and reinstall the wheel.

Routine Maintenance Advice

To ensure the long-term safety and reliability of your device, we recommend checking the tightness of the drive wheel hub nuts at least once every 2 months as part of your regular maintenance to prevent loosening and wheel detachment.
