The Rowcycle
Invented by Scott Olson, creator of Rollerblade inline skates, this two-wheeler is propelled by rowing with its handlebar, which transmits power to a chain-driven rear wheel.
Because it engages all the major muscle groups along with cardio conditioning, the rowcycle provides twice the workout in half the time. And unlike indoor stationary rowers that can become monotonous to use, the rowcycle lets riders exercise amidst ever-changing scenery and terrain outdoors to keep workouts challenging and fresh.
