You could put a 32AH lipoly on there without changing tires or anything.
Weight is around 5 pounds!
I made the 4AH battery from two 2AH batteries just for the test.

This motor is really worth checking out.
For instance on Ebay there is an 8 pound 500w motor.
In contrast this outrunner motor offers more watts and is only 8 ounces!
That is a 16th the weight.

At 10 volts this 8 ounce outrunner has 6480 rpm (it is 640kv)
So it needs reduction or a small shaft if driving friction.

Outrunners may offer more torque, power and efficiency in a smaller package than most the motors used on bikes today. Let me know if there is a reason why they are not being used.
