Small electric scooters and pocket bikes

I just can't leave my yellow BladeZ alone. Now, I've added an E-10 Rad2Go motor and a Curtis controller courtesy (and cash) of Craig U. I was running 10 awg wiring throughout, but am now thinking of using 6awg. My question is, should I use the same 6 guage wire to bridge the brushes as for the wiring coming out of the motor? I have already eliminated the soldered connectors and will be adding a direct injection squirrel cage blower to the side of the motor to keep things cooler. As you can guess, pictures will follow!

I have a s1000 schwinn with a blown controler how can i upgrade, cheaply to 48v ? Can i just add a battery to a new controller? or do i need a new controller like a Crystalyte 35 amp or the goped 1500w?

I was looking at a local thrift store and saw a scooter that looked like a RAD2GO but was not sure as it really did NOT have any definite markings on it. All it had was some surfing stickers, etc. on it and what looks like a 24volt charger wrapped around the handlebar. I took pictures of it with my phone camera so the quality is not that great. Can anyone identify it ?? Oh yeah the scooter looks like it is missing a key to start it, they are asking $70 for it, but may offer $50 for it, if anyone thinks it would be a good one to mod, etc. Please let me know.
