The bicycle isn't all wood. Many of the components are made of steel, and the tires are rubber, as on any standard bike. Individual components include an eight-speed hub and a 120-millimeter disc brake. And it's no lightweight--this first effort tips the scales at a ponderous 52 kilograms (114 pounds).
A weight loss program could be in the offing--Eichler is ready to try his hand again with a "Renovatia II" design. "My goal for the second frame," he writes on his Web site, "is to develop a (safe) and lighter frame for the bike market."
