product design students doron manber and liran cohen of hadassah college in jerusalem have designed a minimalist modular bicyclethe four connecting parts work with four screws that lock the various elements one chooses for the bike frame. in their prototype, the designers use a repurposed vintage chair, using the modular devices.

the four metal modules connect the the bike through the pedals, wheels, seat and handlebars



with then intent of personalizing one’s own bicycle, manber and cohen give you the liberty of designing it yourself. the DIY elements locked between the connecting parts will determine the character of the bike. the four metal modules connect the bike through the pedals, wheels, seat and handlebars.

this DIY bike allows for personal customization

  • I think it’s a cool concept that will evaporate on contact with reality. Tellingly there is no images or video of the bicycle in action. For starters, the four bolts will not be able to hold the stays in place without a lot of mechanical force that will ultimately compromise the wood. An old re-purposed chair is unlikely to provide consistent strength and rigidity. Wood worm, shrinking & cracking or simply different parts of varying quality wood will make this a short lived product.

  • +1000 to the comment above. Bicycle frame joints receive some very interesting forces, and a handful of grub screws to secure each crossmember is woefully inadequate. In a litigious society a product like this could never be sold – it’s an accident waiting to happen. It’s cute as an art project but bordering on unethical to sell.

  • Hello guys and thanks for interesting in our project!
    This model is still a prototype and it’s in the middle of the development process.
    good things not come so easily and we hope its will be usable soon 🙂

  • Interesting. Made to accomodate delta trike style, & allowing for recumbent & semirecumbent versions turns this into a prototyper’s lab setup. Please expose to MAKE Magazine & similar resources. 3d printing plans might be licensed to responsible parties to expedite class projects; similarly, kits might be sold as weldable base parts to be used with heavier duty structural members once balance, weight & lean characteristics have been tested in easy lab conditions. Any thoughts?
