Well I made the Mini Motorbike,
put on the bigger kelly controller, @ 20s i see it sucks a max so far of about 170 200 battery amps
Had 1.2 kw of battery, it was not enough, so i changed it to 24ah 20s.. getting just over 1.5/6kw b4 my controller cuts out
It does power wheelies from like 0 to 30kmh.. anything over 30 kmh the controller cuts the power
Its set back on torque this new controller, 100% battery current and 70% motor current
Throttle range is 1.1 ------ 3.9 volts
Maybe ill need to try the "speed" setting again, to stop the thing cutting out when i do WOT from 30 kmh to 40 kmh.
After 40kmh I can do WOT it just accelerates hard to 75ish kmh
The controller is hardly heating up at all feels rather bullet proof with the extra heatsink
But overall so far.. if compared to the same size petrol bike/rider, this thing will eat a 125cc bike for breakfast lunch and dinner
once i stop this controller from cutting out from 0 kmh and use WOT to full speed, im sure it could take on a 250cc bike with the same size rider, but power wheelie.
It is a joy to ride off road, the dual suspension sucks up all the bumps, at the end of a ride of hard use, lots of power wheelies ect.. the motor is actually pretty damm warm after.
When ever i ride the thing on the grass, its way to hard to not let the back wheel spin.. gotta take it slower or get some proper off road tyres
Iv spent about $2500 on this project... total amount in parts
Pretty damm happy with that figure for the power that im getting from it.
Magic pie Dual Suspension
Peak 6kw Air cooled
Kelly controller (mini kbs series, smaller than a coke can, can do 80+ battery amps peak, Favorite small controller. Really punchy)
Safe, Beautiful handling.
