Need controller suggestions

[rickeBLMSJ]

I am looking to upgrade my e-bike. I need a new controller and display. Currently, I'm using a 52-volt 20-amp hour battery with a 40A BMS using Samsung cells. I would like to find a controller that can get the most out of my MXUS GDR 19, which uses a Z9 motor wire. Ideally, I'd like to find a controller at 30 amps. I have installed a thermostat wire into the motor, and I'd like to run throttle, cadence, brake cut off, front and rear lights, etc.

I'm looking for something with a relatively small form factor since I'm using a bike that supports a Reaction Dorado battery. I'm not sure if I can find something small enough to fit inside the frame, so it would need to be seat post mount. Please take a look at the photo of the bike. Any suggestions would be welcome. Ideally, I would love to have torque sensing, but I can't find a controller that will support both throttle and torque, or anything that will work with a 52-volt battery. Any suggestions would be wonderful. Thank you!

A lot of people use the Phaserunner for applications like that. It's quite expensive and a bit complicated to setup, but once sorted, it does a good job. Note that you need other stuff to go with it. It's not direct plug and play with your stuff:

Looks like Rick is in the USA so should find something suitable.

I have been down the GRIN controller route, get stuff for DD not useable for Geared hubs with a throttle not a class 3 solution and they have no fix.

I'd suggest sorting out that front wheel puncture first...
