Direct Drive RTR

Grin's Ready-to-Roll (RTR) kits are largely pre-configured hub motor packages that include a downtube battery pack with an integrated Baserunner Motor Controller. They are clean to install and use our new waterproof CA3-WP device with integrated handlebar switch for turning the system on and off and adjusting pedal assist levels. See the RTR Intro Video or the Kits Summary Page for details on the motor choices, and the Advanced PAS Page to understand the PAS and Torque sensors.
