Why Is My ENGWE EP-2 Pro Showing E025 on a YL80C Display?
Exact model: ENGWE EP-2 Pro
Safety: Disconnect the relevant power source and isolate moving, hot or pressurized components before service.
A.
Start with the accessible checks
What this suggests: YL80C E025 is related to the brake cut-off signal.
What to do
- Turn bike and battery off and verify both brake levers return fully.
- Remove external obstructions, check brake-sensor plugs and follow each lead for pinching near the folding stem.
- Reseat or replace a confirmed failed lever sensor/harness that matches the EP-2 Pro wiring.
Still not fixed? Continue to the next check.

If the problem remains after the first checks
What this suggests: A brake lever held partially actuated, misaligned sensor or crushed cable can keep power disabled.
What to do
- If input remains falsely asserted with a verified good sensor, service the controller input rather than disconnecting brake safety permanently.
Confirm the repair
Motor assist stops when either brake is applied, resumes only on release and the display no longer reports E025.
