Cycling has always been a good way to exercise, but the Varibike aims to make it even better, by working out a larger number of muscle groups simultaneously.
The Varibike was designed as a work-out solution as well as a therapy solution. It coordinates and creates new synapses in the brain by using leg and arm propulsion. It has an intuitive inclination steering system, which will help build muscle. Thanks to selective pedaling, individual muscle groups are allowed to recover and regenerate during a ride.
In addition to the workout improvement, the makers of the Varibike say the increased input from both arms and legs can propel their bike up to 30% faster than conventional pedal-powered bikes.
The Varibike FR2 costs €3,999 (~ $5,350 USD). The FR3 adds separate freewheels to each arm crank, which allows you to use them side-by-side, in a rowing motion. It costs €4,499 (~ $6,019 USD).
