The Mac Motor is a High Power, High Torque, Geared Hub Motor intended for Spoked Bicycle wheels from 20” to 700C. Rated Output power is typically between 500 to 1000W 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 on the 500W motors to ensure a long trouble free life (gears for us have long outlasted the bearings). 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,
The Mac motor uses a 32 magnet, 16 pole motor unlike the vast majority of geared motors on the Market, which use an 8 pole motor.
The Mac 500-2000W rear motor allows both disk brake and 7 speed freewheel to be used on the standard 135mm dropout.
This is their internally geared hub motor that allows the motor to spin about 5 times faster than the axle. This has many benefits compared to direct drive hub motors that spin the axle at motor speed. Electric motors are more efficient and torquey when they spin at higher RPMs. This motor has the power of direct drive motors twice its size. It weighs just 9.5 lbs and is only 7.5″ in diameter.
Here are the general speeds you can expect with a compatible 36v battery.
48v will provide much faster speeds:
6T – 28mph
8T – 24mph
10T – 20mph
12T – 15mph
For the speed controller we recommend the Infineon 9 fet 36/48v compatible 25a. If you would like something different, contact us. This controller is Cycle Analyst Compatible, and can be used with a 3 power level switch, cruise control, and e-brakes.
This kit is sold with the Alex rim that is compatible with most standard wheel widths. (Please contact us if you need something more narrow or wider).
After order, plan for a couple weeks for the kit to ship to us before we can convert your bike or ship the kit to you. Call or e-mail to see what we have available in our shop right now!
NOTE: Federal Speed Limit is 20mph with throttle only. A Cycle Analyst directly plugged into the Infenion Controller can be set to reduce Speed and Amps to meet Federal guidelines for Electric Bikes.
