The Croozer Kid for 1 or 2 Bike Trailers are the few convertible bicycle Trailers that come complete with all conversion kits required. It is sturdy, sleek and built with quality material. I would consider one, if you like getting value for your hard earned money!
The Greener Gadgets Design Competition brought tons of great green ideas into the limelight, from composters and Twittering electric metering devices to cardboard computers and public bicycle service systems. One of my personal favorites was the entry by Eco Pioneer, a DIY solar bike trailer. It's a modern day covered wagon, ready to power your next adventure.
