52V 50Amp Shunt Modified BBSHD Controller
Please note this voids any and all warranties. We do not cover blown motors or damaged primary gears resulting from use of this controller. We recommend to ride with caution, this is a lot of power and needs to be used responsibly.
This is extremely powerful and will require at minimum a 30Ah battery with high power cells.
You can run a lesser battery but you will not be able to reach peak power of the controller
We highly recommend this be installed on a high quality mountain bike with hydraulic disc brakes only.
OFF ROAD USE ONLY
