Speed controller recommendations??

[ynot]

Have a small supply of 80 Volt greenworks batteries, want to use one to power a freighter bike, plan to use a PM Brushed motor of about 1200 watts at 80 volts. Any recommendations for a speed controller.
Would expect it to be PWM based, but cannot find any suitable candidates.
Suggestions & recommendations would be welcome.

Aliexpress has ebike controllers in that range. Many are sold as 72 volts but state they can run up to 90 volts. You should be able to find something there that works for you.
