This is the thumb throttle that is compatible with Ersin bikes, 

This throttle works with all ersin bike models. 

It is a strong durable throttle, with 3 pin connection. It can be placed on the left or right hand side on the handlebars. 

It's plug and play, no settingup required. 

Alternatively cheaper throttles will not work on ersin bikes, our bikes are specific and require compatible parts designed to work with its programming.
