E-Brakes are a safety accessory that cuts power to your kit when you apply your bike's brakes. They're required by law in some places, and generally are a good idea.
These brakes feature a lock mechanism for use as a parking brake, useful as a "kickstand" to keep trikes from rolling away.
These are for 2017 E-TrikeKits and use DIN connectors.
E-Brakes are a great safety accessory, and these are premium quality.
