Our newest color GALAXY BLACK //  Limited Edition

This one is the same fit and finish as our other JA's, but is a striking color of Gun Metal with tiny silver flakes throughout.......Like the night sky.   It’s the best match for the throttle grip of light black<>dark gray.  

The JA's Throttle Attachment, is designed to fit on e-bike twist throttles with a diameter of 37mm ( /- 1.5mm).

This design allows you to use your twist throttle with ease by using just your thumb - not your wrist. Features a cinch strap that allows for a strong, non-slip attachment to your throttle. Installation takes less than 60 seconds! And enjoyment will last the lifetime of your bike!

Our specific design allows for a no-slip operation. When you push down on the JA Throttle Attachment - The JA is starts to bite into the twist throttle. No it doesn't leave any bite marks but the grip is amazing! Even the hardest riders will have a very difficult time getting our unit to slip!

Our thumb throttle attachments are manufactured here in the United States using a 3D printed process. With 3D printing we are able to achieve a seamless product that provides strength, function and capability that we could not find with injection molding. This allows us to keep our prices down utilizing the benefits of 3D print manufacturing. A win win win!

We're also proud to announce that our cinch straps are hand made here in the United States. Each strap is hand cut, welded and screen pressed with our logo. This allows our product to be officially designated: MADE IN AMERICA. We thank you for supporting an American business.
