My running buddy was cleaning out his magazine pile the other day and brought me an article from the December 2007 Popular Science magazine. It's about an infinitely geared bicycle and it's pretty darn cool. There is no derailleur but rather a rear hub that utilizes ball bearings and a couple of metal discs. It's based on an idea by Leonardo da Vinci - that was a guy who really had it going on. Anyway, the NuVinci transmission is something I'd really like to try out. You can check out "The Ride" at Ellsworth Handcrafted Bicycles. The thing is not cheap at $3,000.00 but quality and innovation rarely is. If you've got a minute, check out the link. You can read the magazine article at either the Ellsworth website or the Popular Science site. If you're in the market to build a bike or have one built for you, the hubs can be purchased at a bike parts supplier such as Alfred E. Bike. The hub might be just the ticket for a cargo bike here in the Midwest. Of course, you still have a couple of days before Christmas if you're looking for that special someone's gift.
