C’mon people, bike is allready invented, there’s no need to reform it year after year, it WILL NOT COME better even that it might look pretty and candy. One thing is clear, weight wheenie rules are for a reason, to build safer bikes, not bikes that crack under pedaling. Saving weight is ridicilous, get rid of your fat instead !

Come on, I will break the frame after 1 pedal stroke.
Or it will break when it hits a hole on the road. What is stopping the chain stay from bending upwards?

Any good school that offers a degree in Industrial Design should be fine for getting into bicycle and sport design. It is really about gearing your portfolio toward the types of products that you are interested in. Here is a good list of ID schools in the U.S. I can’t really speak for the top schools in other countries.

Can you recommend me some good industrial design schools or courses in order to work with bicycles and sport design?
thank you

Nicola, your work is impressive as design and that’s why it is posted on this website. With minor effort and changes this beauty can be done structurally flawless (read some of the “critics” above). Thanks to people like you we all enjoy positive changes in style, design, fashion, traditions and culture.

Nicola,

Welcome — we can be harsh, but we are sincere. Can you speak more to the advantages you think the design choices you’ve made here have over the more common ways of doing things? Beyond the issue of the seat stays, it seems your frame is made of 3 carbon modules that are then joined (head tube, seat tube, top tube + down tube + BB + stays). Carbon frames are traditionally built from either a single, monocoque layup or a modular system of joints and tubes. The former is thought to be the most efficient way to use the material, while the latter has significant advantages in ease of manufacture. A modular design where each piece would need to be specific for each size has no obvious advantage and clear disadvantages. What reasoning justifies this choice?

The Trek Y foil had seatstays, or at least a second set of stays that went to about halfway up what would be the seat tube on a conventional frame. The early softrides also had this design; all softrides are heavy. Note that almost all designs that have eliminated the seat stays were primarily for track or TT, which is of course in some sense natural since those are the places where aerodynamics matters the most, but also assures that durability is less of a concern.

Nobody is arguing that you can’t make a bike with no seat stays, but given the strength advantages of a triangle versus a cantilever it’s incumbent on the designer to prove the advantage in doing so.

The Zipp 2001 and the Trek Y frame suggest you can build a bike without chainstays—or seat tubes. The UCI doesn’t like them, which is why we don’t see them anymore. That doesn’t mean they don’t work.

Thank all for talking about my project. I would like to explain that the rendering shown are only the lastest phase of a project. Before that images the project has passed various discussion with engineer and stress test computer simulation. This in not only a Cad exercise. It is a concept bycicle inspired by Picchio automotive design that need development before production step.This is not the only solution for the future but a possible future. bye
