Troubleshooting

Throttle not working

The thumb or twist throttle doesn't move the bike or scooter. Simple checks before the throttle or controller gets replaced.

A throttle that does nothing is usually a setting, the brake cut-off, the throttle's plug or the throttle itself. Your manual says how the throttle on your model is meant to work, so keep it handy.

Check first

  1. Check the assist level. Himiway says many controllers turn the throttle off at assist level zero, and some are set so you have to pedal before the throttle works (Himiway throttle guide). Your manual says how yours behaves.
  2. Make sure both brake levers are fully released. Brake cut-offs stop the motor, throttle included (Velotric troubleshooting).
  3. With the power off, check the throttle moves freely and springs back on its own. Clean dirt or grit from the housing (Velotric troubleshooting).
  4. Check the grip or brake lever isn't rubbing on the throttle body (Himiway throttle guide).
  5. Follow the throttle cable to its plug. Pull it straight apart without twisting, check the pins for bends, corrosion or moisture, and push it back with the arrows lined up (Lectric E008, Himiway throttle guide).
  6. Look for an error code. On Bafang displays 04 is a throttle fault and 05 means the throttle isn't back at rest. Lectric uses E008 for a throttle error (Bafang C271 manual, Lectric E008).

Stop and get it checked if

If the throttle sticks on, or the bike moves when you're not touching it, turn it off, take the battery out and don't ride it until it's fixed. Both Velotric and Himiway say not to ride with a sticking throttle. Find a shop.

  • The throttle housing is cracked or got wet inside. Himiway notes water or a drop can damage the sensor inside (Himiway throttle guide).
  • The plug and settings are fine but it still does nothing. Bafang's fix for a throttle that fails after the plug check is a new throttle (Bafang C271 manual).

A throttle is a plug-in part on many bikes, so a replacement is often a simple fix for a shop.
