In the season premiere, James and Martin are in Durham, North Carolina, on a quest to brew a beer with the most calories ever. But first, the two take a spin class where they dream up a concept for brewing while biking. Can they engineer the first pedal-powered trolley pub? Then, Martin and James head to Waterfall Farms to gather their own maple syrup, pair it with delicious local bacon, and toss it into their invention. See fitness meet gluttony in one of the coolest contraptions the show has seen!
