Here is a thumb throttle with On/Off switch and speedometer for electric bikes and scooters that is a true bargain in replacement parts. This aftermarket thumb throttle is made to fit the standard size 7/8" diameter handlebar and comes equipped with a 70" wire harness made up of five wires and three connectors.

An On/Off toggle switch is integral to the throttle, as is a speedometer with its LED display panel.

If you are building your own ebike or scooter, this may be a perfect control. Please refer to the photos to get a better idea of the configuration. A thumb throttle like this may find its home on a wide range of brands and models.
