Riding your bike outside is lots of fun. What if you are not ready to go out? The Up-Ride is a bicycle accessory that turns your favorite bike into an elliptical to give you a low-impact workout. You can attach or detach it in a couple of minutes. The Up-Ride comes with elliptical footpaths to simulate running.
This tool simply lets you use your bicycle as a fitness machine at home. It is expected to become available next year.
