The Front Max45 All-Axle motor is available in 2 different winding speeds; a slow 7.2 rpm/V option and a standard 9 rpm/V model. For 72V operation we generally recommend the slower motor winding to get the highest torque output given the 90A phase current limit of the Phaserunner motor controllers. 
There are axle adapter sets for conventional 135mm slotted dropouts and for 15x150mm thru-axle dropouts commonly used with fabike frames. The motor can also be mounted single sided by people with their own fabrication tools using a 16mm steel axle and the DIY SS torque arm.

You can get a bare hub and lace it into a suitable 32 hole rim yourself, or choose to get a professional wheel build done here at Grin using our stock rim selections and quality Sapim butted spokes.  Our head wheel builder Robert has decades of experience and is renowned for building wheels that are nearly bombproof. 

If you want Grin to do the wheelbuild, be sure to select either the Silver or Black spoke option from the dropdown menu, along with your preferred rim. By default all wheels will be be dished with the rim dead center between the dropouts, if you require some special dishing offset for an oddball frame please mention that in the order comments.

If you are doing your own wheel build into your own rim, be sure to specify the required spoke length in the order comments to match your selected rim ERD and lacing pattern. If you require a wider rim than the ones we carry, you're welcome to source your own 32 hole fatbike rim and send it to us for your wheel build. Please get in touch with us to get an RMA # for the rim shipment.

At the moment the only 72V compatible controller that Grin offers is our Phaserunner. This mounts easily to the bicycle frame tubing and supports peak phase current of up to 90A, with continuous current of 45-50A.

Throttles, ebrake levers, pas sensors, and torque sensors all play a roll in how you interact with the ebike. The Torque or PAS sensor plugs in directly to the motor controller and provide assistance based on the assist level of the display, while throttle and ebrakes hook up to the Main9 Superharness. If you are confused about the PAS and Torque sensor options, please see our pedal sensor info page.  Even if you choose a PAS or Torque sensor as the primary control, we always recommend having a throttle as well. It can be handy to accelerate in tight situations and is great as a back-up if ever the pedal sensor has issues.
