If you have any fitness bike, e.g. Peloton, you can add a fantastic experience with VirZOOM (see more at virzoom.com). With VirZOOM you use a virtual reality headset and a stationary bike to move around in VR. The faster you pedal in the real world, the faster you move in the virtual world. Earlier versions (which I have) used either the Oculus Rift, HTC Vive or PSVR for PS4). The newest versions just coming out now are the Oculus Go and the even better Quest (scheduled for March). You can add a VZfit sensor and game button to your existing stationary bike. I’ve been using the early version since 2016. I love two things about this system. The virtual reality aspect which allows me to turn my head in any direction and see what’s there, and gives a true sense of your activity. It puts me in the action, rather than watching it on a flat screen in front of me like other systems. The second thing is I can’t just pedal a stationary bike. Too boring. I have to be playing a game to keep me interested. I particularly like the flying horse (Pegasus) games and the attack helicopter game. Those are intense games, but for people who are a little queasy there are “comfortable” and “moderate” games, such as F1 style track racing. There are biking courses, such as riding up the California coast. The most exciting development coming soon is Google Street View. You can basically ride your stationary bike on any street that’s available on Google Maps. I loved this concept so much I was an early investor in this company. There are still opportunities to invest. You can contact them directly if you have interest.
