Push style Tripwire universal brake cutoff sensor. Adds ebrake functionality to an existing brake system without needing replacement levers. This Push style works with most hydraulic brakes and some mechanical levers, where the action of pressing the brakes causes a compressive motion that can push on the tripwire control cable. Terminated with 3-pin HiGo connector for plug and play compatibility with Bafang BBS and related systems. Manufactured in USA.
