RadWagon Error 30 Troubleshooting Guide

To troubleshoot an "Error 30" message on a 2019 RadWagon, perform a connector check to ensure all connectors are secure and in good condition.

Warning_-_Transparent.png If you are not confident in your ability to safely and successfully perform all steps, we recommend having the work performed or checked by a local, certified, and reputable bike mechanic.

Tools Needed:

  • Flat side cutters
  • A camera
  • Zip ties

Connector Check Steps:

Perform the following steps on each connector until the error message is resolved.

  1. Prepare the bike for maintenance. Press and hold the MODE button on the remote until the bike turns off, then turn off the battery (remove the battery if more space is needed to access a connector). Press and hold MODE again to discharge remaining power.

  2. Locate and unplug the connector. Follow the cable from the part to the connector. Snip zip ties for easier access, then pull each side of the connector directly apart without twisting.

  3. Inspect the inside and reconnect. If the inside of the connector is wet, dirty, or damaged, take a photo and contact Rad Power Bikes Product Support. If it looks normal, line up the internal notch and pins (and external indicators) and press directly together without twisting.


  4. Test the bike. Reinstall the battery and turn on the bike. Repeat steps 1 through 4 on each connector until the error is resolved. Once resolved, replace zip ties and trim to be flush and smooth. Test the bike fully and ride Rad!
