Luckily i wasn't paying for machine time !! :wink:
It was my first build so maybe it is geared a bit low but everyone seems to have overheating problems with this motor at higher
power levels. I felt that if it was geared lower that i would sacrafice top speed for hill climbing ability, which is the whole reason I went
mid drive. It will do 50 Kph as is and at this stage I'm ok with that.
There is a 219 kart chain with a 14:76 ratio to the cranks and yes it was inspired by Boostjuice, there is a free wheel at the crank and support
bearing. There is another free wheel at the motor to allow non powered pedling with out the resistance of the motor.
I may play around with the ratios at some stage but I'll put a few Ks on it as is first.
