SLIM QR Thumb Throttle for Electric Bikes – Waterproof HIGO Connector
SLIM QR Thumb Throttle for Electric Bikes – Waterproof HIGO Connector
The SLIM QR thumb throttle is a compact and convenient electric bike throttle that allows smooth motor power control using your thumb. Thanks to its slim design, the SLIM throttle takes up minimal space on the handlebars, ensuring comfortable operation and easy access to other bicycle controls.
One of its main advantages is the QR (Quick Release) mounting system with an opening clamp, allowing the throttle to be installed without removing handlebar grips, gear shifters, or other accessories. Simply open the clamp, position the throttle on the handlebar, and tighten the mounting screw. This solution makes installation significantly faster and easier.
The electric bike thumb throttle features a waterproof HIGO connector, providing a secure and convenient connection to a compatible electric motor controller.

Quick Installation Without Removing Handlebar Components
The SLIM QR thumb throttle with an opening clamp is designed to make installation as simple as possible. Unlike traditional throttles with closed mounting rings, it does not require removing rubber handlebar grips, brake levers, or gear shifters.
Thanks to the opening mounting clamp, the throttle can be installed directly at the desired position on the handlebar. Simply loosen the screw, open the clamp, position the throttle, and tighten the mounting screw again.
This practical solution is particularly useful when converting a regular bicycle into an electric bike, upgrading an existing electric drive system, or replacing a damaged throttle.
