Yojiro Oshima, a design student at the Craft & Industrial Department at Musashino Art University in Tokyo, has designed a completely hand-crafted wooden bicycle. The wooden bike features a sculptural wooden frame that softens the ride while retaining an optimal level of stiffness. Yojiro used hollowed-out 6-12mm sections and bonded them together to create a network of rims and spokes. The curve at the top of the spokes absorbs impacts, and the beam-style seat tube improves overall comfort. The bike has tri spoke-style wheels, known as baton wheels, which feature an arc between the spokes and rim that is designed to reduce large impacts. Yojiro experimented with the different frame and handlebar shapes to achieve an optimal structural configuration that would be independent of the material used for making the bike.
