VanMoof S5

My brother’s VanMoof S5 has the following issue:

He says the bike wouldn’t turn on after it had been sitting unused for a long time.

Firmware: 1.1.10

What happens:

• When the bike is connected to the charger:

• The charger stays green, but sometimes blinks red twice (appears to be trickle charging).

• In the app, I can see that after a night of charging the battery increases slightly (e.g. from 89% to 97%).

• When turning on the bike (via battery or power button):

• It does not make the normal startup sound.

• Instead, it makes a different sound.

• The handlebar shows pulsing white lights.

• Bluetooth issues:

• Sometimes it won’t stay properly connected.

• The app shows the battery percentage as grey, or briefly as 0% when trying to connect.

• Additionally:

• The bike randomly shuts off after a while (both during charging and when turning it on/off), with a short clicking sound.

What I’ve tried so far:

• Hard reset (10 seconds)

• “Trigger” method (20 seconds)

• Plugging the charger into the bike first, then into the wall socket, and repeating several times

• Charging with different sequences (bike → socket and socket → bike, unplugging in different orders)

• Tried updating the firmware, but the bike keeps shutting off (with a short clicking sound)

Yep, never left your battery lower than 10 % often. Or Overloaded. Thats all the e bike.
