This attaches to the existing throttle on your eBike and creates a thumb throttle. It just slips over your existing grip and clamps down on the throttle when you engage it with your thumb. You can easily adjust the position while riding your ebike, by just twisting it in the opposite direction. It was designed to be easy and it uses no hardware.
Thumb throttles are said to be more ergonomic, they create an easier way to engage the throttle with having gloves on, and they are inexpensive. Of course you could add a completely new throttle assembly, but why would you need to when you have this!
Note: We have not tested this with “every” ebike, so your mileage may vary. We do guarantee that they will work with Lectric, Rattan, Ariel Rider, Magicycle, and Dirwin ebikes though. They will work with most twist throttles.
