KIT-GrinR-FAT_Bare
Grin Rear Max45 All-Axle hub motor kit with optional battery pack and your choice of a Baserunner or Phaserunner motor controller. If a Baserunner controller is selected along with a downtube battery pack and Reention baseplate, we will mount the controller inside the battery cradle for a very clean install.
Motor is compatible with both 170mm and 190mm quick release slotted dropouts, and 177mm and 197mm thru axle dropouts, by selection of the right inserts and weighs 6.2kg. Features 0.35mm laminations, a Statorade injection port, and available with a Shimano HG or SRAM XDR compatible freehub.
The barebones system uses a throttle with an integrated on/off switch and voltage readout that is compatible up to 72V, but doesn't have a proper display or control options for the integrated torque or PAS sensor. It's good for simple ebike builds that want to avoid any additional complexity.
The throttle also includes two extra wires for running a front bike light and hooking up an ebrake sensor. The ebrake levers provide a fixed level of regenerative braking which is OK, but not quite as nice as the varying proportional regen that is possible with a V3 Cycle Analyst.
