RadMini Error 30 Troubleshooting Guide

To troubleshoot an error 30 message on a Radmini, perform a connector check to ensure all connectors are secure and in good condition.

This guide uses photos of RadMini models from 2016-2018, but the steps will be similar for most RadMini models.

Tools Needed:

  • Flat side cutters
  • Phillips head screwdriver (for 2016-2018 models)
  • A camera
  • Zip ties 

Connector Check Steps:

Perform the following steps on one connector at a time until the error message is resolved.

  1. Get the bike ready for maintenance. Turn off the bike, remove the battery, and press MODE to discharge remaining power.
  2. Check the battery and battery mounting tray terminal contacts. If it's in good condition, reinstall the battery and turn on the bike to check if the issue is resolved. If the bike will not turn on, remove the battery and discharge remaining power.
  3. Check the connection between the battery and the controller. The battery connector is the large connector located near the bottom bracket. The connector is flat on one side and is black inside with two large prongs. Follow the steps below to check the connector.

  4. 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.

    For 2016-2018 models: Use a Phillips head screwdriver to remove the cover plate on the box beneath the battery to access the connectors inside.

  5. Inspect the inside of the connector and plug it back together. If the inside of the connector is wet, dirty, or damaged, take a photo and contact Product Support. If it looks normal, line up the internal notch and pins (and external indicators) and press directly together without twisting.
  6. Check if the issue is resolved. Reinstall the battery and turn on the bike. If the issue continues, turn off the bike, remove the battery, and discharge remaining power.
  7. Repeat steps 4 through 6 on each connector listed below until the error is resolved. Once resolved, replace zip ties and trim to be flush and smooth. On 2016-2018 models, reinstall the cover plate on the box beneath the battery. Test the bike fully and ride Rad!
