RadMission Communication Error Troubleshooting Guide
If your RadMission fails to power on or the Pedal Assist Level lights on the LED display are all flashing as shown below, you can troubleshoot the issue by resetting the connection to the bike's electrical components.
This process will help reset the connection to the bike’s electrical components. It is important to check all connectors, even if they appear to be fully seated and in good condition.
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
- Camera
- Zip ties
- A table, wall, or friend to help stabilize the bike, or wood blocks (to protect the display when the bike is upside down)
Do not insert any tools into the connectors, use metal tools on the internal pins, or attempt to straighten bent bins. Doing so can lead to irreversible damage to the component or cause injury or death.
The process for checking the connectors below will involve unplugging the connector, inspecting the inside for damage, plugging in the connector, and turning on the bike to check if the error continues while the connector is plugged in.

Battery Tray Connector
- Get the bike ready for maintenance. Turn off the bike, remove the battery, and press and hold the power button to discharge remaining power.
- Stabilize the bike. Have a table, wall, or friend ready to help keep the bike in place, or carefully flip the bike upside down and prop the handlebar grips on blocks to protect the display.
- Check the battery and battery mount terminal contacts. Visually inspect the terminal contacts for any dirt, damage, or moisture.
If the terminal contacts are damaged or show signs of moisture, do not attempt to repair the damage or clean the contacts. Take a photo and contact us for more help.
If the terminal contacts are in good condition, continue troubleshooting.
- Locate and unplug the battery tray connector. Locate the cable that exits the bottom of the battery tray and trace it until you find the connector. Snip zip ties for easier access if needed, then pull each side of the connector directly apart without twisting.
- Inspect the inside of the connector for damage, dirt, or moisture.
If the inside of the connector is damaged, dirty, or wet, take a photo and contact us for more help. Do not attempt to fix broken or bent pins or clean the inside of the connector.
If the connector looks normal, continue troubleshooting.
- Plug in the connector. Line up the internal notch and pins (and external indicators) and press directly together without twisting. Replace any snipped zip ties and trim them to be flush and smooth.
- Reinstall the battery and turn on the bike to check if the error is resolved.
If the error is resolved, the connector was likely loose and triggered the error. Test the bike fully and ride Rad!
If the error continues, turn off the bike, remove the battery, discharge remaining power, and continue troubleshooting.
