Mac Rear Motor

Here is the brief introduction of MAC geared hub motor:


The Mac Motor is a High Power, High Torque, Geared Hub Motor intended for Spoked Bicycle wheels from 16” to700C. Rated Output power is typically between 500 to 2000W depending upon the motor winding selected and the operating voltage. An internal 5:1 planetary gear with clutch is implemented. New stronger Composite Gears are now standard  to ensure a long trouble-free life.

What’s the difference between Mac Hub Motor and  DD Motor?


The gear reduction allows the motor to spin at a higher and more efficient rpm greatly improving the starting torque and hill climbing ability when compared with comparable Direct-Drive motors, whilst also being smaller and lighter than a comparable DD motor. The clutch offers minimal drag when not under power. Unlike the majority of geared motors on the market, the Mac 500W is built for the high-power demands of the US market, not the highly restricted EU market. The slower wound versions could still be used and stay within the EU speed limit, for those requiring more hill climbing ability than the typical 250W motors can offer.
