what do you mean "push button throttle"? is it just a on/off and then works off a pedal sensor?
Man they seem like a dirt bag company. no real instructions at all had to really look to find that stupid push button throttle that is by far the most horrible thing I have seen on a ebike.
so on the upside its a bafang motor so you can just buy a controller off ebay and throw their stuff in the garbage.
