Well after my most successful EV project being my first Hub powered electric bike, I am very impressed with the hub motors (2 previous, were scooter style). My current setup is great for on road riding since I have around a 30mph top speed, cruiser tires, no suspension, and a rear bag carrying batteries. I see no end in sight for this bike but desire my original purpose for getting into electric vehicles: DIRT! What I want is high torque, around 18 mph top, full suspension, nice downhill tires, wheelie popping ability.
To achieve this I am looking into the puma motor mounted in a 20in wheel. After getting to ride xyster puma power bike I was impressed with the torque for the size and weight of the motor. I plan to run my setup on 2s dewalt packs so, 66v nominal and 3p. I am really interested in this new puma version with metal gears and heavier wiring. I am hoping to run around 35 - 40 amps, so over 2500 watts. Can the motor handle this kind of power or will it burn up?
My second question is: will these motors or any hub motors be able to handle harsh off road conditions (Big bumps, dirt, sharp hits). I think of what I ride over with my mountain bike and picture the magnets falling off, windings shorting, ect. Even with full suspension it doesn't help what the motor has to deal with, it only helps me keep the wheels on the ground and give me a more controllable ride.
