Why are there discrepancies between my outdoor PowerTap numbers and my CycleOps indoor cycle numbers?
Due to external factors of riding a bike outside versus riding a solid indoor cycle, you may experience different values on your PowerTap. Also, with the special design of the flywheel, inertia plays much bigger role in your workout on the CycleOps indoor cycle versus riding your bike on the road. For instance, a larger effort is required to get your indoor cycle flywheel up to a certain speed, but due to inertia, the flywheel will spin much longer than a regular bicycle wheel, resulting in less work being required to maintain that predesigned speed.
