Can we agree that 35 mph can take as much as 2000w on a MTB? Who's able to pedal 30% of that for miles and miles? Most of us are hard pressed to put out 150w for ten or more miles. So at 35mph, you aint gonna pedal up 30% of your wattage. closer to 5-10%.
I put a 15 ah battery on a bike two times, once racing, once dirt riding. Both motors smoked. But the conditions were flogging the motor as hard as possible. Cruising on paved is different, But I have many times had a plenty hot motor( smelling the toasting windings, no way you want to touch it) after an 8 mile cruising ride at 45 mph. I say limit speed to whatever you can get for about 1500-2000w continous. That level should go the distance.
