My son used his DYU for 1 year now and sudently nothing worked.

I plug the charger, it’s coming green when the battery is full but the trottle does not light, on/OFF button does not work, etc.

Where is trouble coming from?

I do not have complete explanation from my son what’s happen exactly.

Do I change the controller card or motor? where can I buy them?

Hi, I got a new D3+ but after the first trip out and charge, it won’t switch off. The throttle and pedal assist stay active when the LCD is switched off, also Bluetooth stays active.

If you leave the screen on, it does go off after 10 minutes, but again throttle, pedal assist and Bluetooth are still active.

Also Bluetooth app appears to be misreporting the battery charge, its taking 0.44 KWH on my charge meter each time, which allowing for losses would be about 360 watt hours that the battery is, so I believe that the battery is fully charging, however Bluetooth showed 100% at full charge the first day, then after 20KM use 75% and after a further 20KM use 58%, but then after charging it went DOWN to 40%

I then rode it 36KM throttle only, and it went down to 3%, and the LCD only went to 1 bar when the Bluetooth went to 4%. Fully charged it again and it only went back up to 30% and then dropped to 28% despite being switched “off” Checked again this afternoon and the throttle and pedal assists are still on despite the LCD being off.

Really shouldn’t do that for a new bike.


Removing the Bluetooth board, the screen goes off (as before) but the pedal assist and throttle still are active even though the screen is off.

How can it be the Bluetooth board if the issue happens when it’s not connected, or does the Bluetooth actually determine actually switching it off?

The bike is new, how does it get repaired?
