this is not really a homework question, but it would make a good one!!. i posted it in the classical mechanics forum, but did not seem to get much help

i have a two wheel rims, 50mm thick, (ouside radius 500mm, inside 475mm) connected by 8 horizontal spokes. between two of the spokes on opposite sides of the wheel are basket holders, such that the wheel is in perfect balance, and when a weight is dropped in one basket the wheel revolves and moves forwards, dropping the weight when it reaches the bottom of the wheel (the other basket is for symmetry/balance) by using a 2.2 kg weight i have had the wheel roll an average of 55m (61.3 max!) it takes 2.4 secs to complete one revolution, giving an RPM of 25

my question is how can i work out the theoretical maximum distance i should be able to get from the weight?

2. Relevant equations

not really sure, this is what i am trying to find! i know

I = 1/2m(r1^{2 + r22) angular velocity = v * r do not know how to work out friction, or how to take it into account 3. The attempt at a solution I am not studying physics, and have very little knowledge of it, bar what my internet research has turned up, so i really do not have a clue where to start. some relevant formulas or a link to a good instructional site would be appreciated, thank you}
