The upside to this motor and the reason for it's existence is reliability and hill climbing without having to worry you will damage the motor.
Yes you have hit the nail on the head there!
For me the only good thing the cromotor has over the pie is the fact it can take about 4kw constant and much more peak so will eat hills and survive!
The pie would be happy at 40 mph all day. But dumping 3kw in for 2 miles or so will get it very hot up a 16% hill, I don't think te cromotor would have issues with that.
The pie is also a super torque wind and slow enough where the cromotor is a faster wind.
The mac is a truly fantastic motor and I miss it something terrible, I think once the clutch is sorted, and the axle, keyway then it will be the ultimate motor up to 40 mph and it will happen as cell-man is committed to improving it all the time! It has taken me up hills so much faster than the pie with incredible torque all the way to 40 mph.
Again super hills are the enemy of smaller motors, but the mac's lightness, free wheeling, speed and torque and efficiency are what sets it apart from most other motors and what makes it my favourite motor for a bicycle that is!
Back to pedal only power.
