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.

This page covers the Ride1Up Revv 1. Its display shows a fault as a number, and the codes are not the same as on other Ride1Up bikes, so don't read them against a Core-5 chart. The list follows Ride1Up's Revv 1 table (Ride1Up Revv 1 codes).

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 4: throttle not back in neutral, stuck open or faulty. Check its cable plug and that it returns.
  • Error 5: throttle malfunction. Same checks as 4.
  • Error 7: over voltage, a sensor reading too high or faulty. Ride1Up points to the cadence sensor and throttle.
  • Error 8: motor hall cable fault, the motor cable may be damaged or loose. What to check
  • Error 9: motor phase cable fault, same cable checks as 8. What to check
  • Error 10: motor too hot. Switch the display off, let the motor cool, then power on.
  • Error 11: motor temperature sensor failed. Ride1Up says the motor needs replacing.
  • Error 12: current sensor fault. Inspect the controller cables, a shop job.
  • Error 13: battery too hot, so the battery cuts power. Switch off and let it cool before riding.
  • Error 14: controller too hot. Switch off to cool; a shop checks the internal controller plugs.
  • Error 15: controller temperature sensor not working. The controller needs checking or replacing.
  • Error 21: motor speed sensor not working. Check the rear wheel connection.
  • Error 22: battery management communication fault. Ride1Up's general code page lists this for the Revv 1 with a check of the battery connections (Ride1Up error codes explained).
  • Error 23: headlight not working. Check the light's plugs.
  • Error 24: headlight sensor fault. Check the headlight plug.
  • Error 25: brake sensor needs adjusting. Unplug the brake shutoff wires one at a time to find the cause. What to check
  • Error 26: speed signal fault, disconnected or faulty. Check the motor wiring.
  • Error 30: communication error. Check the display plug and the controller connection.
  • Error 39: internal controller fault. Ride1Up says the controller needs replacing.

Before you call a shop

  • Watch the display when the problem happens. Ride1Up notes codes may show only briefly, and the number is the most useful thing you can give support.
  • Pull over, switch the bike off, wait about five minutes and restart, which is Ride1Up's first step for an overworked system.
  • With the bike off, check that the throttle springs back and both brake levers return fully.
  • Follow the motor cable from the rear wheel to its plug near the chainstay and make sure it is aligned and fully seated, especially after a flat or wheel removal.
  • If the code stays, send Ride1Up support photos or video of the problem and a list of the checks you've done.
