I need to build a 3 wheeled frame. i need either a mid frame kit or a hub motor kit, its either a one front and two back wheels or 2 front and one back. wheel. power can only go to the one wheel only. I need a kit that can run for a 1 hour and 10 minute race and has to at least do 40 kph, ( 40kph when on the heavy 3 wheeled steel bike) the school previously uses 700 watt geared hub motor kits. that sit on 40 kph and for batteries they use lead acid at 36 or 48 volts. i looked at cyclone.tw and bms battery kits . please let me know if i should use a hub motor or chain drive motor and where to get it from i also need to buy batteries (obviously to make it run for 1 hour, 10 mins) and total cost can be not a cent more that $1,200 aus. but pref $800 max is I'm 15 and have to pay, please help out, thanks
