Burley Travoy Bike Cargo Trailer

Love leading an eco-friendly lifestyle by biking to-and-fro, but miss the convenience of being able to haul larger quantities of goods? Pick yourself up a Burley Travoy Bike Cargo Trailer ($260). Fully collapsible and lightweight thanks to its aluminum frame, the Travoy attaches to your bike's seat post, and tows behind your bike on two large, sturdy wheels at a 45-degree angle. Once you reach your destination, it fits neatly inside the included tote bag, or you can detach it and use it as a shopping cart — although you can expect to draw more than a few odd looks if you try that anywhere but the grocery store.
