The Treadmill bike is a "bike" that's powered by walking/running on a treadmill instead of by pedaling pedals.  The idea is somewhat interesting, but the video on the site shows that the product is laughably ridiculous.  Other "bikes" on the site include the Couchbike, the HulaBike, and the Rowingbike.  I would say the website is a joke, but videos prove that these products exist and can be used.  (via Mental Floss) #sports
