What brand of old scooter is better?

There are several reasons why electric vehicles can't kink when powered on:

1, on the one hand, the reason is that the line of the controller power-off system is flooded. Divided into leakage, electric shock and other power outages. This is the control system. There will be power failure.

2. On the other hand, it is caused by the speed control handle. If there is a fault in the internal circuit of the handle, the connecting wire can be replaced. If it cannot be replaced, the entire handle can be replaced.

If the above two situations fail, or the maintenance is not good, then go to the maintenance network for maintenance as soon as possible.
