"2-way acceleration with “regen braking,” LED & off switch,
clamps to standard 7/8” diameter handlebar
Our unique patented (U.S.A. # 6,144,125 plus other pending) electronic throttle looks to be the picture of simplicity, and it is; but, we are embarressed to say how many complete redesigns, heaps of scrapped out protype parts and cold cash we spent perfecting this now simple reliable device. First of all, it clamps onto a standard 7/8" diameter bicycle or scooter handlebar and takes the place and position of the normally right side mounted derailleur twist grip. Basically, it is a torsion spring balanced two way twist grip device with an integral off switch at the home position, with multicolor smart LED's for operator information. After you have pedaled or pushed the vehicle (a unique safety feature of this design) up to 2-3 mph, turning the twist grip counter-clockwise accelerates the vehicle; releasing the grip allows the vehicle to coast and twist grip to return to its home position; turning the grip clockwise at any time, turns the hub motor into a generator and you get progressive regeneration or electric braking, efficiently putting energy back into the batteries. One nifty, but easily taken for granted feature of the design, is that actuating the electric brake at any time automatically shuts off the motoring as the hub motor-generator is either one or the other; it can not simultaneously be both, no matter what condition or age of the vehicle. When the motor device is a seperate structure from the braking device as in other designs, this safety feature cannot always be taken for granted as parts wear, maintenance is neglected and people forget to tend to it. Highly intuitive, this throttle is quickly mastered and appreciated by new riders as it eliminates the skills necessary to master gear shifing; one merely twists and goes or brakes; you don't even have to remember to turn it off, as even this is automatic. This throttle is specifically designed to be used only as part of our #500W System; any other use instantly voids our warranties and it is not recommended."
Has anyone use it? Could it be used with a kelly controler?
