Most of what everyone said I agree with. Except just remember a life fitness bike has little to do with real world speed. It is a good training aid but the speeds posted are a guess as best. I once read an article by a trainer that was working with a over weight women and told her to ride a stationary bike at an average speed of 12 MPH for 20 minutes. She discovered she could kick real hard on one pedal and then let it coast down to 12 before having to kick again. Seemed strange but he simply wanted to empathize what extremes some people will go to in order to avoid any extra effort. Keep at it and you will get so a 20 or thirty mile ride seems like a warm up.
