[anyone know from doing Pizza delivery which required you to use
your own car?, taken depreciation, fuel, maintainence, cost's, etc]

You just take 1040 and probably Schedule C for business use of personal auto. Anyhow, you can do it though maybe not Schedule C. I think you have the option of itemizing fuel, insurance, and depreciation or taking a standard per mile deduction. Keep good records and keep them for a minimum of three years. Be aware that depreciation lowers the cost basis of the car when you sell it.
ETA: That's three years from the time you dispose of the asset, by the way. I wouldn't consider it with a bike unless it were high dollar and it were exclusively in business use.
