Bicycling is a fantastic way to get your daily exercise, but if it’s your only form of exercise you’re only working a small group of muscles over and over. Caron, a concept bike, can propel you along in six ways, working a wider number of muscle groups every time you ride.

The bike can be pedaled normally, or you can change modes with a thumb switch. Then you can ride by moving both feet in revolution, revolving one foot (either side) while the other rests at the bottom, both feet moving up and down, one foot or the other moving up and down, or alternating moving both feet up and down.

The difference between the Caron and a regular bike is its unusual crankset. Instead of only allowing a single range of motion, the patented Uniset’s components move in novel ways that let each pedal operate independently while still moving the bike forward. It’s an interesting approach that lets you work more muscles than regular bicycling alone.
