I’m a huge fan of Brooklyn-based Areaware, but I was surprised to see they have a bicycle in their collection. Well, not just any bicycle. The Strida bike features a lightweight aluminum frame, with power transferred to the rear wheel via a Kevlar belt. The bike folds up for easy storage or transport — which is a good idea as this bike wouldn’t last five minutes on the street. It looks like it would be a fun ride, but I’m not sure if I would want to draw that much attention to myself — I might get nervous and fall off. Strida just got a big honor as a 2011 Best of Green Award Winner from Treehugger, my favorite blog focusing on sustainability. Strida is $650 and comes in multiple color options.
