The G-Bike is a transforming stationary cycle designed by Dongwan Jo. The G-Bike features an electric battery and can instantly go from your home to the streets.

Jo's concept is compact and is perfect for those who live in cramped urban environments. The bike can be transformed quickly and easily by simply pulling on the frame. The exercise version of the G-Bike helps you break a sweat indoors and charges the bike's battery for use out on the road.

Many designers are creating similar hybrid designs in an attempt to save consumers a bit of money and space. Multifunctional exercise equipment such as the G-Bike may very well be featured prominently in the home gym of the future.
