The thumb throttle for the Hiboy® S2 electric scooter is a perfect fit because it's the real McCoy. This thumb throttle (or "finger-dial") comes complete with the 3-wire harness and a black silicone thumb pad.

We also offer another top-quality but economically priced aftermarket substitute. Our replacement 3-wire thumb throttle will make an excellent replacement for the original.

Note: Hiboy® is a registered trademark of Freeman Investment Holdings Limited. The new parts listed for the Hiboy® models are aftermarket parts and not Hiboy® OEM products. Each part has been verified by Monster Scooter Parts staff to be compatible with the listed Hiboy® model.
