Description
A replacement 21V twist throttle with a 19mm grip, built for Strider electric conversion kits running a 21V system. Among our current catalog, that’s the 12in kit, though the supplier’s own listing describes it generically as fitting “Strider electric conversion kits” without naming a specific size.
Grip size is confirmed at 19mm, smaller than a standard adult throttle grip, matched to the hand size of a younger rider rather than scaled down from an adult part.
This is a direct swap for the kit’s original throttle. If your bike is running a 24V system instead (our 14in kit), see the 24V twist throttle listing, the two aren’t interchangeable.
