Can someone help identify this hub motor ?

I bought an e-bike, the ignition caught fire and the owner sold it very cheap.
the rear wheel works but i cannot find any info on the bike or the hub motor.
all I know is that it was 36 volts (3 batteries)
this is the bike.


the rear wheel has no markings indicating what type of motor it is, but it looks like this one.


I am building a chopper bike and was going to use a chain driven motor but then came across this, so i decided to buy it for the motor.

Does anyone know if this is a brushed or brushless motor ?
(the hub motor assembly is heavy)

also i want to use direct power, (no controller) it will be 2 switches with relay, 0ne switch supplying 24 volts the other 48 volts (2 speed)
but the 2 wires coming out of the hub look very thin, they look like they will melt under load, can these motors handle direct power or do they have to have a controller ?

Thanks

how manny wires are coming out of the motor?

2 wires brushed
3 wires with smaller ones brushless.

if its brushed you could just use a switch.

Thanks for your reply karma,
there is only 2 wires, i hooked up 36 volts to it with a toggle switch for about a minute to test it and it pulled me along good.
i just wasn't sure if it was brushed, or if it can handle straight power supply because of the gauge of the 2 wires, they are thin (very thin for a 36 volt bike)
i have an 18 volt motor that came off an electric pocket bike and the wires are double (maybe more) the thickness.
i'll try it on my project and see how the wires handle the load.
Thanks
