Likely causes
- Aftermarket or wrong charger pushing the pack past 54.6V
- Freshly charged pack slightly above the cut-off
- Controller voltage sensing fault
- Aftermarket 52V battery on a 48V Rad controller
How to fix Rad Power Bikes error 07
- Unplug the charger; ride a few minutes on assist level 1 and power cycle

- Use only the Rad charger or one with the same output voltage
- If the voltage is fine and the code stays, contact Rad support about the controller
Go to a dealer if: Go to Rad support or a shop if the voltage checks out on a multimeter.
