Derestricton ?

I have a direct bike DB50QT-111 that does up to 30mph. Do you know how to de restrict it? I looked under the battery but there’s nothing there.

You will have to modify the variator and the exhaust.
For the variator you will need to take the drive belt case off, undo the front pulley nut then take off the pulley and belt. There will be a washer sitting behind the belt, remove that and the job's done.

The exhaust is difficult, you have to weld shut the disrupter pipe (it's just an extra pipe that leads to nowhere and disrupts the exhaust pressure).
