Designing a wooden bicycle frame Mk4

About a year ago two friends and I started working on a wooden bicycle frame and this video summarises the process so far. There's still a long road ahead but I am convinced it will continue to be an incredible journey. thanks to you Cedric and Armin, without you two I probably would have never even dared to tackle this project.

Cooles wooden Bike! 👍👌

Oh, an alternative to clipping the plywood could be to sandwhich a sheet of metal between the wood, I've seen others do that for plywood projects to give it additional rigidity
But then you get into the problem of using metal lol

Hello! Did you try putting carbon fiber between the sandwich layers? Possibly it would give the wood a lot of rigidity in all directions of wobble. Thank you for sharing your experience.

Cool bike mate ! I'm asking myself why did you not want to make the vertical axis ( seat tube ) in wood ?

[@makermind2050]

Well the top section needs to be a metal tube in order for the seat tube to slide in. So the only way we see to do that is "surround " a metal tube in wood. It feels unesseary and adds a lot to the weight. That being said it forces you to make the metal to wood connection on the top and bottom of the seat post tube very strong to not lack stiffness. Now on our mk7.5 we finally achieved a really nice connection. I'm surprised that no other wooden bike frame we found online ditches the wood surrounding the seat tube.
