Hey there,
Thought I would drop in and say hello, perhaps you will find my new design interesting and we can have a good time building it out over the coming weeks.
As a background - i have been working on composite manufacture processes for a while now, the frames I have built so far have been carbon filament-wound tubes with carbon lugs, no metal anywhere other than some liners for rear wheel clamps.
This time I wanted to make something different, need some spice in life you know - so this is essentially a carbon beam frame design with aero seat stays - ala Hope/Lotus track bike and as of these olympics - Toray, Look etc also followed suite.
This design was optimized using CFD simulations, targeting 30kph+
Screenshots show a track frame, but i have since decided to change over to a 1x geared road bike instead.
So far I have made 2 prototypes, one to check part fit - the second to check ergonomics by riding it. Now im working on final frame production process and mold, generally posting updates on my Instagram most often as its easy to do
I was at the Eurobike but not as an exhibitor, dont recall seeing this bike you mention - there was the Lotus 136 there though, is that what you are thinking of?
Thanks! Im sure the design will evolve further over time - but i feel its good enough for this stage
The first prototype was purely 3d printed, enough to fit all the parts and check everything gells together. The second one was a 3d printed core, over-wrapped with carbon (pics on instagram) - which I rode around on to check ergonomics etc, was really fun and I really wanted to keep riding it instead of continuing with the project.
Probably the wildest part of the second prototype was that it went from a purely digital CAD design to being ridden in just 4 days. Printed, wrapped and built up in less than a week - crazy!
