Battery and electrical safety. Lithium-ion batteries can catch fire if they're damaged or charged wrong. Never open a battery pack, and stop using any battery that's swollen, hot, wet or smells burnt. Every edit to this page is checked by a second person before it goes live.

The RadMission has Rad's LED display, a row of pedal assist level lights with no screen (Rad RadMission guide). It shows a fault by flashing particular lights. Rad's error guides give the flashing pattern for each code on LED displays, listed below. Note which lights are flashing before you switch off.

A code that points at the motor, controller, wiring or battery is an electrical fault. Do only the plug checks on this page, with the bike off and the battery removed, and leave opening the motor, controller or battery, soldering or rewiring to a pro or the maker's support. See battery won't charge and when to call a pro.

Codes

  • Error 22, assist level 1 flashing: a throttle problem. Check the throttle cable connector first (Rad error 22).
  • Error 23, assist levels 0 and 1 flashing: a problem with the motor phase wires. Check the motor cable connector first (Rad error 23).
  • Error 24, assist level 2 flashing: often a motor hall fault (Rad error 24). What to check
  • Error 30, all assist level lights flashing: a communication error. The bike may also fail to power on (Rad RadMission guide). What to check

Before you call a shop

  • Power off, remove the battery and press the power button to drain leftover power before touching any plug (Rad error 22).
  • On the RadMission the motor connector sits on the rider's left chainstay (Rad RadMission guide).
  • Follow Rad's order: battery and mount contacts, battery tray plug, display, harness, motor, lights, brakes, throttle, headlight and pedal assist sensor. From the motor plug on, Rad also has you test with each part unplugged (Rad RadMission guide).
  • Don't put tools into connectors, use metal tools on pins or straighten bent pins. Photograph damage and contact Rad (Rad RadMission guide).
