That GE motor will be a lot easier to hook up because it has the driveshaft.
Either motor should run a motorcycle just fine. It's hard for me to tell the scale of the motors from the pictures. I think they would be a bit small for a car, but could work, as long as you are only looking for real basic transportation.
The motor on my Metro weighs a bit more than 60 lbs.
What's the diameters of the motors?
You might want to make a call to Advanced DC, they make some nice motors, including ones specially made for EVs. You might be able to get some more specs on the Advanced motor form them.
Hooking the "female" connection to a transmission takes more work though.
Forklifts are great to strip parts from. A forklift controller worked fine for starting the Forkenswift project. Same for Russ' Voltzilla.
