Staying in shape has never been easier. But don’t stop there, the Big Rig Pedal Desk ($2000+) also puts your legs to other uses while you get some work done. It’s handmade from welded steel frames, bicycle parts, and an optional generator. The generator can generate 100 watts of electricity, pump 5 gallons of water per minute, grind a variety of grains, or operate an air compressor. It can also operate almost any hand-cranked machine or small shop tools. So forget about that spin class and go for The Big Rig.
