Make sure your pinions gears are wide enough so the can of the motor doesn't hit the driveline. For mod 1.0 to be used and if there is 5 cm of space between the motor shaft center and the driveline you, need more than 100 teeth total (pinion + spur). For 13 and 14 tooth pinion gears to be used, your pinion gear must be at least Mod 4.0 pitch. I still don't see how you get 2440 watts out of that motor or how it will pull 81 amps. I've never heard of scooter motor making anywhere near that amount of power as the human body can easily out run and out accelerate anyone on any electric scooter ive seen and were talking less than 500 watts. I can output about 550 watts on a rowing erg which uses all the major muscles in your body and an olympic rower does about 750 watts during a race.
