You can't add the motor directly to the week as you need the wheels to be as light as possible to reduce what's known as "unsprung weight" - suspension performance is critical for a performance bike as with any other vehicle where traction at high speed is required.
You are both wrong I'm afraid, chaps. Audio CDs are read at constant linear velocity, which means that when the data is being read from the middle of the disc it must spin faster. So, going from the beginning to the end of the content, which works from the middle to the edge, the rate will indeed decrease from ~500 to ~200rpm.

I think the Casio looks like an SLR, but isn't actually one.
