This is the 48V 20A brushless controller for the Hitway BK10 electric bike. The controller is the unit that reads the throttle, brake, and pedal sensor inputs and decides how much current to send to the motor — it is the part that turns a battery into controlled drive. When it fails, the bike usually does not respond to the throttle at all, or cuts out under load.
The 7099 designation identifies the protocol group this unit belongs to. Protocol is what separates a controller that works from one that physically connects but never communicates: the display has to talk to it, and the harness pinout has to match. On a 48V system with a 20A current limit, this unit is configured for the BK10 platform rather than adapted to it.
