rode great but then the axle broke! too much leverage. duu. looking at all these hub motors in comparison to the span of axle the farthest bearing sits at and supports a typical wheel I think it was only a matter of distance..and I went deep into the distance.
going back to the old model and will squeeze a bit bigger stator in and increase the second bearing to monster size as well and call it done.
aside from the quest for the most continuous wattage, which the long motor was going for, running two smaller ones had tons of power and good for anything under half an hour and with the two motors and the vesc's traction control it really was a better ride. no slips on wet or loose ground and no loss of power when doing a sharp turn by lifting the motor off the ground.
mission not accomplished but mission completed.

anyone who wants to take on the only other long one of these motors I have 10 lifetime's supply of rubber and will give it to you at the manufacturing cost with shipping at...235. and can throw in a pair of paris trucks and kegel wheels at half their retail price. it's a 47x70mm stator with curved n45sh magnets. .2mm stator lams. and monster sealed nsk bearings. with the last link I posted, assuming it will fit an 80mm wheel I think it would spread the rider load enough to be good. or mount it to something else.
