This one of a kind, hand made wood tandem bike is sure to turn heads. Two German engineers teamed up to found WWG in 2006. Stemming from a rural town in the Ore Mountains, Jens Eichler (AKA Lot) and Matthias Kranz (aka Ast) combined their educational backgrounds in wood and metal works for their bicycle projects. “As a wood engineer I’m looking all the time for special projects, which are a change in the standards of the present. So I started out with first drawings to find a good look for the frame. At the same time I’m using a static programme to find the proper dimensions of thickness and stiffness,” said Lot.
“My goal for the second frame is to develop a more safety and lighter frame for the bike market. At this time I’m working on the drawings for the second bike.”
 This particular rendition includes a completely functional prototype that took 400 hours of woodwork to craft (see detailed pic after the jump), so we doubt that translates into cheapie commercial product. Much of that labour was in carving away 10kg (22 lb) of laminated beech plywood, to arrive at a finished frame-only weight of 27.5kg (61 lb), though 52lb is quoted elsewhere. Fully specced out, the bike weighs in at a rather hefty 52 kg (114 pounds) Not exactly lightweight, even considering it is a tandem for two riders. Nevertheless, Jens Eichler, of WWG, a woodwork designer in Germany is pretty happy with the final result, and has plans to embark on a safer and lighter second version.
