Now have fatbike hubs for all you storm owners that need more power.
You can get torque 12t or hi-speed 6t.
Also an 8t, t=turn, the windings on the motor.
I am using the 10t and it will go 26mph on 12s lipo. 200lbs bike and rider.
This thing will pull the front wheel off the ground at 20a 1000w setting.
Some over at endless-sphere have run these at 2000w for a while.
I have been putting 16a in mine and it feels similar to the Pie at 25-30a.
Great motor, I don't even ride my Pie any more. I mean the Pies are nice and all but they really kill the bicycle feel to me. The MAC still feels like a bicycle, you can pedal it no problem, very little resistance.
I pedaled the Pie for 2 miles no power and it really sucked.
To be fair my Pie runs in a extended cruiser frame and the bike is about 25lbs heavier with the battery in frame(have only just retrofit it to backpack battery) than my mountain bike/Mac.
Maybe the Pie would wheelie this Mt bike?
