The following description didn't make sense to me until I watched the 33 second video at the bottom of the page. [...] this transmission is both continuously variable and completely automatic. The wheel can adopt any effective gear ratio in the range between its minimum and maximum diameters, and it does this passively like a spring, as it responds to loads on it by shrinking its diameter until it achieves the maximum diameter at which it can consistently rotate. ... And now I want these wheels for my bicycle. Yep, there sure are a lot of reasons why that wouldn't work. Shut up and take my money! :)
