Hey, guys, my first time posting here but I need some educated individuals to definitively solve a problem from another forum. We are having a discussion about a bike on an incline treadmill (one presumably made for a bike). My contention is that it would still be relatively easy to pedal on this since you are not gaining any potential energy by riding it like you are a outdoor incline, and the gravitational force pulling back is equaled by the friction from the tires on the 'mill surface. Once again I'm not saying it will take no energy but the energy will be fairly minimal if the treadmill is self powered, all you really need to do is provide the energy for the rolling resistance basic inertia of the wheels and the wind resistance of the spokes in the wheels. Thanks for your help!
