From the site:
When the weather's nice, the last place you want to be is cooped up in some stuffy gym. Imagine running through evergreen forests or strolling down country roads. All of this is possible thanks to the rugged design and all terrain tires on the revolutionary Treadmill Bike.Not for nothin', but why do you need to be running "through evergreen forests..."? What's wrong with riding there? Or if you want to be running... why not just run?
I just don't get this one. Thanks to Dave for forwarding; it's a prime example of a design whose time may not EVER come - at least for me.
