Simple Brush Motor Controller (with e-abs)

[StAnkys]

I need an e-bike/scooter motor controller that has an electric brake (regen a plus).
HOWEVER, it is for a BRUSH motor, not a brushless, and has a simple 3-wire (5-wire ok) 5kohm twist grip throttle, and identical 5kohm twist grip brake as inputs.

Attached is the wiring diagram I desire.

Does anyone know where I can get one (cheap preferably because of simplicity and minimal features), or know how I can accomplish this using off-the-shelf components?

More specific detail:

Voltage: 24VDC Brush
Current: 30A peak, 15 nominal


Thank you in advance
