Control Stuff

	Controllers Here is Grin's listing of stand-alone motor controllers. While we used to have a range of generic controllers like the Grinfineon, Crystalyte, and eZee offerings, we decided to pair this down to just the Phaserunner and Baserunner series which have maximum versatility and can be configured to work with virtually any brushless motor model.
	Controller Accessories Various mounting brackets, cables, and connectors that relate to our motor controller offerings.
	Cycle Analysts The Cycle Analyst is much more than just an old-looking display and is the central control feature for most of our advanced kits. With some custom throttle wiring you can also use it (via the Stand Alone or High Current models) to add PAS and torque control, thermal rollback, current limiting, low voltage rollback, and numerous other features to generic 3rd party controllers too.
	CA Accessories There are a number of input accessories, mounting accessories, wiring accessories, and repair parts available for the Cycle Analyst devices.
	Superharness In lieu of a Cycle Analyst, the Superharness provides an alternative way to link displays, throttles, ebrakes, and lights to our V6 Phaserunner or Baserunner motor controllers.
	PAS/Torque Sensors Options to add automatic pedal assistance to engage the motor on your bike.
	Throttles Linear hall effect throttles which will output a 1-4v signal when powered with a 5V supply. Twist or lever style.
	Ebrakes Ebrakes are regular brake levers that have a built-in switch to let the electrical system know that you are braking. This can trigger regenerative braking in non-freewheeling hub motors, or safety cutoff in geared freewheeling motors.
