With 72V systems it almost always makes the most sense to get the standard speed motor winding, as the high speed option will spin much faster than you will ever be able to attain on an ebike. The RH/FH212 motors have large M14 axles which is better than M12 axles for resisting spinout, but given the motor power we still encourage the use of a suitable torque arm. 
Statorade is recommended at these expected higher power levels.

You can get a bare hub and lace it into a suitable 36 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 and just require the spokes only, be sure to specify the required spoke length in the order comments to match your selected rim ERD and lacing pattern.

The Baserunner controller is ideal if you are getting a downtube battery as we will mount it inside the battery cradle.  The larger Phaserunner is required if you need an option that can run up to 72V, or if you are using one of the other battery models. It will also produce slightly higher peak torque due to the 90A vs 80A max phase current.

The V3 Cycle Analyst is an integral part of this kit system that ties together the throttle, ebrake, PAS, and torque sensor signals into a highly configurable platform that can be readily customized for a range of performance behaviors you can't get anywhere else. As a display it may look a tad clunky, but the functionality it offers is simply unparalleled and continues to increase with each new firmware release.

Most 72V batteries you find are rectangular packs held together by shrinkrwrap, but we've got some options for 72V batteries with proper molded enclosures that fit on your downtube or inside your frame triangle. 

Throttles, ebrake levers, and pas sensors all play a roll in how you interact with the ebike. Torque and PAS sensor automatically power the bike whenever you pedal with an assist level controlled by the CA3's MFSwitch, while a throttle gives manual control. Please see our PAS info page for more details on these options

Unfortunately the torque sensors are not compatible with 72V systems when powered through the CA as it will overheat the regulator, so we only have basic PAS sensors listed with 72V setups. 

The ebrake levers provide the means to activate regenerative braking, which can then be modulated by the throttle.  

There are a optional accessories that can help flush out the build, but be warned that most ebike electronics are only designed for up to 60V max operation. The items in the list below are all 72V compatible and will not fry from the high voltage battery.
