MAC 12T High Torque Motor Winding Option for customers who want higher torque for hill-climbing. This will result in a slight decrease in top speed.
Winding more copper around the motor's stator gives you more torque and less speed. Less windings will give you more speed and less torque. The MAC motor and most other motors of this type can only be set up with one type of winding.
The production HyperFat is set up with a 9T winding which was selected to target a top speed performance of 30+ mph with pedal assist, yet provide good hill climbing performance.
For riders who are heavier or have more hills, we have a 12T motor winding option which provides more torque performance, but reduced top speed. The estimated top speed of around 25-26 mph with the 12T setup. With this option chosen, only the motor is changed everything else remans that same.
