The Wheel Turns
Stationary exercise machines are now on the move - Elliptical
The ElliptiGO lets bikers climb hills more easily than on a sit-down bike. Its footrests slide back and forth on fixed rails like on an elliptical trainer, but this pair transfers power to a rear-mounted eight-speed hub via carbon-fiber arms and an oversize bike crank. Since the arc of each stride is longer than on a regular bike, there's more room to harvest energy, allowing bikers to quickly climb 20-degree inclines and reach 25 mph on flats.
