Dear folks
Got troubleconfused:
Got Folding ebike 20" so far Perfect since last Night
Next Morning ...
Bike Not working
Battery full charge ....Test it
chk wires with tester no Prob.

The funny is that some times working for 2 - 3 seconds and then goes Death.
After long speculation made the conclusion

Could be if your using Lifepo4? Could be a BMS issue? Try meter reading on output while engage the motor. That should answer the question.
