Hey all,
I bought a rad2go for cheap, the seller said it had been ridden about 5 times and his son rode through a puddle and it stopped running. He also said that after that he took the hub motor apart and water poured out of it. Think this thing will ever run again, or should I start looking for a new hub motor?

Ok, so I ordered a 750w dc motor, brushed controller, chain, and 72 tooth sprocket for the rad2go subird. Any guesses as to speed? Hopefully it'll go pretty good.
Keep the rubber side down and the shiny side up.
Motor/controller and sprocket came in yesterday. Today I'll see what I can do to make motor mounts and somehow attach the sprocket to a dead hub. This should be interesting. :(

I got to work on the Sunbird some today. I got the motor mount installed.
Then installed the motor
Then installed the controller to test it. The motor turns really slow. Even though it's 36v, it's rated for 36v 2500rpm, it's barely moving. Also, it only turns with the key "off". If I turn the key on there are lights, etc.. but no motor. Any ideas? The diagrams said to wire the battery, motor +, and controller + together, but this isn't right.
Here's a video link, tell me what you guys think.

Hope to get this thing running soon.

Um.. That's going to have a problem. What happens when you go over a bump, the swing arm swings? What will happen to the chain from your motor? Won't your chain go slack? And possibly fall off?

I thought about that, but the shocks are so stiff they don't even move if I bounce up and down on the seat as hard as I can and if it does I'll weld steel to make it a rigid rear end.

I got some speed out of the motor by adding another battery and going to 48v. This bike's wiring or the controller is kooky!

We recently got one of these (also cheap, with no info), and have been trying to figure it out.
First, there's a user manual that has a few useful pieces of info at: http://www.manualnguide.com/manual-get/18136/
Second (from that manual): The ignition position determines which battery you're using.
LEFT: uses Battery A (near the pedals: can be charged in OR out of scooter.)
MIDDLE: Off (use when charging)
RIGHT: uses Battery B (under the seat: can only be charged OUT of the scooter.)
Good luck!
