I’m seriously interested in your design and would like to discuss further both designs in particular options for your Ferrari design. I’ve been looking for some time someone who could build me a custom carbon fibre design. You’ve achieved very close to what I want to build.
Please let me know if you are interested.

I made those (and a few more) bikes for myself, never meant to offer them to customers, so dimensions suit me only. But starting next month, August 2012, I open business making custom frames, any shape imaginable upon customer’s request, from classic diamond shapes to ridable artwork. Will be located in Minneapolis area, feel free to contact at 610-515-5229. Thanks for interest!

What would be the dimensions of this cycle ?

Thank you so much and sorry, I do not have website, but James Thomas added a link (see last “update” text after pictures) to my Picasaweb photo gallery, where you can find my email address.

I want a quote for the oval, brilliant!

whats your website?

I would add that using FEA to analyse carbon fibre designs is significantly more complex than metals or non-reinforced plastics (not to mention the thousands of dollars of computer equipment and software) The amount of energy wasted here by using too much material in the lay-up (if any) would also be significantly less than the electrical energy used to design the frame in a 3d CAD package and carry out computer-based FEA.

thanks Carbon, not using energy was not my goal, just an interesting challenge among many others during the whole process.

the designs are great, very beautiful indeed.
However you do not end up being green by not using electricity to use computers to design. You can find optimum amount of materials needed by FEA methods and use less carbon fiber/epoxy, in turn using much less energy. Carbon fibers are quite energy intensively produced.

Thanks Logan, within month or two I hope to finish couple of downhillers with unique suspension and instant gear change under load, very light and strong frame design, tested already. In the cases above construction methods were invented for the particular seamless (one piece) carbon frame, process is too detailed to explain here.
