The belt i got is one that others who use the kickr have bought, and it's designed for a car - I know I'd like to think I can push big numbers, but even in my wildest dreams I don't think I can put out more power than a carI'm guessing just a tad, but I suspect that being a cheap belt it is prone to stretch under heavy load, whereas the original is better quality and has a higher tensile strength. Difficult to compare without data specs of. others belts
