The SX motors are available in 2 different winding speeds (fast and standard) depending on how fast you need to go for a given wheel diameter and battery voltage. In most scenarios, we recommend the fast wind for 20" wheels and the standard winding speed for 26" and larger.

Because of the high torque capability of these geared motors combined with the smaller diameter M12 axle, the use of a torque arm to prevent axle spinout is essential.  

Small Front Hub Motor with Helical Gears, Standard (~7.5 rpm/V) Winding. Includes 9 Pin Z910 Cable with Combined Speed + Thermistor Signal.

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 Z9 controller supports up to 55A peak phase currents and will be mounted neatly inside the cradle of our downtube batteries. If it is purchased with a flatpack or bottle battery we will terminate the short power leads with anderson powerpole connectors, and would recommend getting one of the optional mounting brackets.

The V3 Cycle Analyst and control switch is an integral part of this kit package.
