Aventon error E25: Brake error

Medium severity Service immediately

Can I ride home with this error?

Stop riding. Do not ride with assist until the brake cut-off works; check the brakes stop the bike.

What it means

The brake sensors cut the motor when you brake. This code often appears if a brake lever was squeezed while the bike was switched on; otherwise a sensor may not be working.

Likely causes

  • Brake lever squeezed during start-up
  • Faulty or misaligned brake sensor

Symptoms

  • E25 on the display
  • No assist

How to fix it

  1. Turn the bike off and on again without touching the brakes.
  2. Check the brakes work normally by hand.
  3. If it stays, unplug both brake sensors, then plug in one at a time and switch on to find which side brings E25 back.
  4. Contact Aventon support and tell them which side is faulty and the brake lever brand.
