Yojiro Oshima wooden bicycle frame handlebar and wheels

We saw quite a few wooden bicycles at NAHBS this year (here, here and here), plus some sweet wooden fenders and bags from Nisnas on Kickstarter. The most recent tree-sourced bike comes from Yojiro Oshima, a student at Tokyo’s Musashino Art University.

The pictures come from BicycleDesign.net, where you’ll find more of them (though we did do a little color correction on them here), and where Oshima commented that this is only a prototype and that the material is, well, immaterial…that it’s the shape that’s important. Then he added that wood would be the most comfortable.

This one’s construction uses hollowed out sections bonded together, much like Connor’s designs from NAHBS (middle link above). It’s unfinished, evidenced by the lack of brake levers and full cable routing, but still quite beautiful. Particularly the handlebars…

The curve at the top of the spokes is designed to absorb impacts and combines with the beam-style seat tube to improve overall comfort.


  1. Really neat design… and one of the few wooden bikes that actually looks fast!

    That being said, somebody should create a manual for non-cyclist (or even cyclist) designers who decide to try their hand at bicycle concepts. The lack of a front brake, any cables or routing, brake levers, and the terrible set-up of the rear brake pads catch the eye of a lot of cyclists and makes it appear as if little time, thought or cycling expertise was spent on the design. It’s the little things that make the difference.

  2. Textbook bike photo staging. Take notes:

    [x] photo from drive side
    [x] shifted to highest gear
    [x] crank arm and spider aligned with frame
    [x] slammed stem

    If those were real tires, I’m sure the valve and label positions would be correct.

  3. A disc brake setup might be more appropriate as I doubt the combination of rubber braking pads and a wooden rim will work.

  4. Joker has a separated seat tube with only a stub to mount the front derailleur. This is a design concept which honestly should have only been realized in CAD, the lack of cables only leads to snarky comments about how much the designer left off. More appropriate for a design site instead of a cycling enthusiast site.

  5. Looks better than the C4 to me with the segment from the BB to the seat stays. While it’s a design exercise, the lack of a front brake is too much of a mistake imo. That’s like drawing someone’s face and forgetting eyebrows or something – it has to be there as it’s a fundamental “element” to the object in aesthetic discipline. But still, looks very nice.
