I just recently finished building an electric scooter and want to move to making an electric supermoto for street use. To make the bike more accesible to others and to make a fun minimoto I am planning on using a cr85 frame with 17" supermoto wheels. My goals for this build are to have 45kw-60KW with a top speed of 100mph. The minimum 45kw is due to the Manual of Motorcyle Sport allowing electric bikes up to 45kw so I am future proofing just in case that rule ever applies in the US. I am planning on using the ME1507 motor from electric motorsports but they dont sell a 120v 550a speed controller. I have been looking for a suitable speed controller but its been proviong dificult to find. As well I am having a hard time finding a powerful enough BMS. I want to run at the max 120V as I believe voltage is tied to RPMs. Can someone help me find a suitable speed controller and BMS?
ME1507 ($1,500): 20kw Cont. 55KW Peak, 48v-120v, 550A peak for 1 minute.

Speed Controller: Require regenative braking
BMS: I would like a single BMS but I was thinking of taking two 60V 600A BMS in series or four 60V 300A BMS in 2S2P.
Battery: I am looking to use lithium pouch battery as they have a high C rating and high capacity
