The G311 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.
These motors have round axles (3/8" x 26 tpi) with internal tabbed washers to resist axle spinout. For most fork dropouts this is sufficient, but we also make a custom torque arm that replaces the inside washer on the right side and secures against the fork fender eyelet for added security.
▼ The 20th Anniversary $20 price for the motor will show when you add this kit to the cart! ▼
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.
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.
The kit will run with any battery pack from 24V to 52V nominal (and up to 72V with a Phaserunner). We offer a range of batteries that will work well depending on the geometry of your bike, the range you need on a charge, and how fast you want to go. Please see our battery info page for more details on the different pack options.
Be sure to select a charger model that matches the voltage (36V, 48V, or 52V) and connector style (ST3 or XLR) of the chosen pack.
▼ The 20% discount off LiGo 10X Packs will show up when added to the cart! ▼
There are a number of optional electronic and mechanical accessories that can help flush out the build. This includes front and rear bike lights, phone chargers, wire management, programming cables, and what have you.
GRIN Front Torque Arm for G311 Motors. Replaces Disk Side Anti-Rotation Washer. Requires Fork with Fender Eyelets. Full Product Information Page
Throttles, ebrake levers, pas sensors, and torque 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
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.
The ebrake levers can be included for a motor safety cutoff whenever you squeeze the brakes.
