[Troubleshooting]Power Cut-Off Issue on Surron Light Bee

Bike Information:

• Model: Surron Light Bee X 2023, L1E (Street legal)

• Ownership: Since December 2023

• Mileage: 4800 km

• Typical Use: Mostly street riding with some light off-road (no heavy jumps)

• Mode: Usually ride in C0 (uncapped mode via brake brake lever controller coding)

• Braking Setup: Regenerative braking used initially, but currently turned off. E-brake sensors deactivated(P0).

Recent Issue Timeline:

• Issue Onset: Began around mid-summer, 2 months ago

• Weather Exposure: Some rain riding, but the issue didn't occur during or after rain exposure.

What I've Tried:

1. Checked and reconnected all plugs (controller and horn)

2. Tested without e-brake sensors (issue persisted)

3. Regularly cut power before unplugging and follow proper startup protocol (wait for the screen to display 0)

4. Always charge between 20% and 80%

Additional Info:

• Bike is completely stock, no modifications or cut cables.

• The horn also stopped working (plugs checked and seem fine).

In the video below, I detail the problem and explain what I've tried so far. If anyone has encountered a similar issue or knows where to start (new controller, battery, etc.), your advice would be much appreciated! ​ Video : https://www.youtube.com/watch?v=_VAaaGTlcvU
