I've built a 1000 Watt scooter (750W over-volted) that gives half decent performance.

But i want MORE power! I want the fun of the build again, not just the end of the journey!
So I have a new plan. I'm thinking about building an electric mountain bike, but one which will look very discrete and barely noticeable to be electric from a distance. Yet one that packs an awesome punch.
People have mentioned this 6000W HXT monster RC motor that could be a potential EV motor. 6kW though seems like far too much power. A mountain bike chain alone would struggle to cope with 8 hp. So I've found a smaller version for a lot less money.....

With a 2.8kW MAX input from my NiMh battery pack from my previous build I reckon this motor would be a very decent candidate! Over 3hp on a mountain bike should provide great performance on the flat, but what about off-road??
These RC motors are great at handling high current loads. I will arrange my NiMh packs into a 24V x 2 parallel system capable of >100A peak, but I am very very dubious about the torque of these motors. they are used to spin props on rc planes with no load apart from air resistance on the blades. Not for driving high loaded wheels. Could it actually move a bike if geared to a standard "normal" ratio we would use for a normal brushed motor, e.g. MY1020 and MY1016 models.
There's a very simple 100A speed controller on the same website....

coupled with a £10 servo controller from ebay the entire package of motor+ESC+"throttle" INCLUDING P+P FROM USA TO THE UK is only £70!!
about $140!!! Absolute bargain, too good to be true??
So does anybody have info on the torque these motors can produce for an application such as an e-bike or e-scooter?
