i just converted mine to 24v if you take a basic controller you
Will blown you're engine...because it is doing to many amps...
or you will have to less power...
i took a basic controller and modified it a bit..
so it does not put more then 29amps on the motor.
doing some tests with it and do the "achterhoek-run"
after that you can buy it from me with a throttle for around 50,- pounds
excl shipping (from the netherlands)
if anyone is interested i will hear it!
