WTB: BLDC motor controller 72V

Years ago I converted a trials bike, it's somewhere in the projects section, anyway I sold it on as I wasn't using it and the new owner is looking for a motor controller now. Max voltage of 83V and 200a peak, 110a continuous was the claim on the controller. It's a 20s battery.
Anyone got anything equivalent or better for sale?

If you / they are willing to go diy,

It will run a few different control firmwares.
Otherwise there are some large vesc controllers out there that should do.

Is an older Kelly any use?

Will make an exception for you regarding shipping to UK from ROI.

That might be of interest, might be massive overkill for the little motor.

Wouldn't be that massive - the Kelly is 150A battery / 300A phase and the motor has some headroom for a voltage upgrade down the line.
It's likely bulkier though.
