Bluetooth remote for the Elecbrake controller.
The Bluetooth connection is used to adjust the settings of the braking profile. The break controller has microprocessors and accelerometers in it. Using these it can regulate or proportion how much power goes to electric brakes. So that means that this is a fully proportional brake controller that operates as good as most others on the market, or better.
This remote let you control the profile without the need of an app on your phone.
