Why are there discrepancies between my PowerTap numbers and my Indoor Cycle numbers?
Due to the external factors of riding a bike outside vs. riding a solid indoor cycle, you may experience different values on your PowerTap. Also, with the special design of the flywheel, inertia plays a much bigger role in your workout on the Indoor Cycle vs. 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 predesignated speed.
