The Grin eZee Front Hub Motor Kit is a front-wheel conversion kit built around the geared eZee Main9 hub motor, sold with a controller, display, battery and pedal-assist sensor. The motor uses thin 0.35 mm laminations and has an internal thermistor and a 6-pole speed sensor on its L1019 connector, so it can report temperature and speed to the controller. It runs on any 24V to 52V nominal pack, or up to 72V with the Phaserunner controller. It suits riders converting a bike with a simple front-wheel swap who want a complete, configurable kit rather than a bare motor.

This is a front-wheel geared hub motor conversion kit built around the eZee Main9 motor. The kit is configurable: you choose a UART display, a lithium battery, a Phaserunner or Baserunner controller, and a pedal assist (PAS) or torque sensor.
The motor uses 0.35mm laminations. It comes with an L1019 connector as standard, plus an internal thermistor and a 6 pole speed sensor. The kit works with any battery pack from 24V to 52V nominal, and up to 72V when used with a Phaserunner.
The motor is available prelaced in 20", 24", 26" and 700c (29") wheels, with tube and tire included. It is also available as a bare, unlaced hub motor. A fast wind is recommended for 20" wheels, and standard winding for 26" and larger. A torque arm is essential to prevent axle spinout.
