Just like that insane Fliz bicycle, the Treadmill Bike seems crazy and a bit impractical to me. It allows you to take your favorite gym workout outside, on your bike.
Yes, it is a treadmill on wheels. The video shows that it’s easy to use, a great workout and a safe way to get around. Basically the act of pedaling has been replaced by running. But why not just pick an activity? Either run or ride a bike, people. All your constant overachieving just makes the rest of us look bad.
However this looks like much more work than either exercise by itself, so the workout here may be better than just riding your bike. Just don’t expect to see these on the road anytime soon. The video was created a while ago, and this concept is just to draw your attention to bicycle design software called BikeCAD Pro.
