The Front Wheel version of the Mac motor is quite tight to the fork on the non-disc side of the motor. Please refer to the drawings listed below to confirm the motor outline will match your fork.
Note: Battery-Fed Shipping MUST be used for shipments including a battery. Lead time for Batteries is ~2 weeks, prior to shipping (if the battery is not built, in stock). Battery-Fed shipping typically requires up to 2 weeks shipping time.
Our Mac Kit with 46.8V Frame Battery Pack includes:
- Upgrade Mac motor (includes upgrade stator and temp sensor) in a built Alex wheel rim of your choice using 13G Sapim Spokes. See Upgrade Mac Kit for more information.
- 25A 6fet 3077 Programmable Infineon Controller with matching throttle, 3 speed and Cruise, as well as a bar mounted power switch and a choice of ebrakes.
- 50V Triangle Pack and 5A charger with a choice of Capacity Options.
- Interconnections between the Motor, Controller, all Accessories and the Battery are plug and play.
- The combined cost for the kit with battery is at a reduced rate compared to purchasing the items individually. Additional accessories such as suitable Freewheel, Disc Spacer, Torque Arm and Cycle Analyst are offered at reduced rates compared to purchasing separately.
The combination of controller, battery and motor have been selected to ensure all parts are suitably matched and working within the recommended limits. Instead of offering choices for motor windings, we have offered a range of typical cruising speeds that can be expected on the flat. We will try our best to provide a motor that will meet or exceed the requested speed.
- There is limited space for the Disc Brake Calliper when using the Mac Motor (15mm clearance only). This means that many better quality and/or Hydraulic Disc Callipers may foul the Motor. So we offer a 2.5mm thick disc spacer to enable more clearance. Another option is to convert to 203mm Disc. With a larger Disc installed, the Calliper can clear the hub and avoid these clearance issues. See: Mac 500W Rear Motor Outline and Mac 500W Front Motor Outline. Please ensure you understand this point and take measures to overcome any possible issues.
- The Mac motor uses a screw on freewheel, it cannot use a cassette. The 11T DNP are popular as it allows you to pedal to a higher speed. The Mac can accept a 7 speed without any additional spacers (135mm axle width). If 8, 9 or 10 speed are used, a spacer of ~4mm is required and the axle width will increase to ~139mm (spacer will be provided). Difference between a Freewheel and a Cassette.
- A Torque Arm is not absolutely essential at this power level, but they are recommended. We offer the full range of Genuine Grin Tech TAs (manufactured in Canada). Choose the appropriate TA according to your motor choice (Front/Rear) and the design of the Fork. See: Rear Rev4, Front Rev3 and Front Rev2 designs. A motor spinout on a front hub motor installation can be particularly unpleasant, so some will opt for dual front TAs. It is recommended only steel front forks are used for a Front Hub Motor installation. A suitably construted DIY Torque Arm is fine. We only recommend you consider this point and take suitable precautions to avoid a motor spinout.
- The HWBS Ebrake Sensor allows you to retain your original cable type meachical brakes and brake levers. The HWBS sensor mounts inline with the brake cable and detects when the brake is pulled. HWBS sensor is not suitable for Hydraulic brakes. 1pc HWBS sensor is ordinarily supplied, it is not necessary to have a sensor on both front and rear brakes, 1 is enough in our opinion. Ebrakes are strongly recommended with this Kit as it has a Cruise Function.
- When the Upgrade Mac kit is combined with the V3 Cycle Analyst, it opens up the possibility to have Motor Temperature Monitoring and Power Rollback if motor temperature exceeds a programmed limit. It also allows various control functions and PAS Assi
