Controllers

Grin's Phaserunner and Baserunner motor controllers: versatile, fully programmable FOC controllers for almost any brushless ebike motor, from 27V up to 88V.

Controller Accessories

Mounts, battery baseplates, motor harnesses, extension and adapter cables, and heatsinks for our Phaserunner and Baserunner motor controllers.

Cycle Analysts

The Cycle Analyst V3 (CA3), Grin's ebike display and dashboard: monitor speed, watts, and battery range, with programmable assist. Shop the cable variants.

CA Accessories

There are a number of input accessories, mounting accessories, wiring accessories, and repair parts available for the Cycle Analyst devices.

Superharness

The Superharness connects displays, throttles, ebrakes, and lights to our V6 Phaserunner and Baserunner controllers. A simpler alternative to a Cycle Analyst.

PAS/Torque Sensors

Torque and PAS sensors that add automatic pedal assist to your ebike, so the motor helps as you pedal. Works with both Cycle Analyst and Main9 systems.

Throttles

Thumb, twist, and half-twist ebike throttles that fit a standard handlebar and plug into any Grin controller. Choose the style that suits your shifters.

Ebrakes

Ebrakes are brake levers with a built-in switch: they trigger regenerative braking in direct drive hub motors or a safety cutoff in geared motors.

These are the electronics that run and control an ebike: motor controllers, displays, throttles, pedal-assist and torque sensors, ebrake cutoffs, and wiring harnesses. Our kits are built around one of two display and control setups. The Cycle Analyst is fully programmable, with your sensors and inputs running through the display so you can tune everything. The Main9 system is simpler: a familiar display, wired with a Main9 wiring harness, where the motor controller handles the configuration and you just see speed, assist level, and battery. Not sure which suits you? Our kit types guide compares the two, or open any category below.
