I have a ZEV S 6000 electric scooter. All I want is a full twist throttle with lcd battery voltage and no key having cruise control would be a bonus. The scooter already has a key. The stock throttle is crap and has almost killed me more than once. And I doubt it can be adjusted by a different throttle but it would be nice if it had a soft start from stop than what it has currently. It really jerks from start.
