WATCH THIS TOO!
Jake bombs a big hill at around 40mph then his foot slipped out of the powergrip and he had to stop by putting his foot on the tire, check out the smoke that comes off! In the process he burnt off some of his leg hair.
There has been debate over his actual speed. We have gone out and re-tested this. The maximum speed (cadence) of his current ratio (according to several gear ratio calculators) is 39.7mph. His ratio is 48-19. Apparently at that speed your feet physically can not pedal any faster. I don't personally know much about gear ratios and their terminal velocity or cadence but I'm researching it more right now.
