Speed controllers to use with mobility scooter motors?

[SnowLabs]

Hi everyone, beginner here! (First post haha)
I'm looking to put together a testbed bot to build off to get started, and I was going to use some mobility scooter motors for the drive. For the ESCs, I was going to use the 85a Tz85a's because I know they're popular, but they are brushless. A lot of people use mobility scooter motors - but aren't they likely to be brushed? If so, can people recommend any high powered brushed ESCs to use? Should I go for the Botbitz 85a Brushed Tz85a, or even the Botbitz 30a Brushed ESC? Would the 30a one be powerful enough for most scooter motors? - Sorry I can't give specifics, most scooter motors on eBay don't detail the specs. Cheers all!
