It appears that your knowledge of bikes exceeds your knowledge of parachutes by several orders of magnitude. I wonder what JSM would say about your use of that fine intellect.

Surely the rear tyre is far too wide for a machine with less than 30bhp ? The ideal proportions should be that of a 125cc racer (albeit beefed up to take the extra weight).

re Luca Bar I like you ideas very much and I am glad to see someone thinking outside the box in a good direction.you are so right lightweight motors are very close along with high output for size.People like yourself are the future for our sport,keep up the great work.

With perimeter discs as a structural part of the rim, a dual set up, the weight difference is reduced. If a race bike say like this was designed with a wheel of some sort of carbon-ceramic compund(assuming it could be used as a structural material) I imagine there would be huge weight savings. Admittably there is still a larger moment to deal with when the weight is concentrated at pretty much the farthest point from the axle. I’m assuming that is why Buell’s have always used 6 or 8 pot callipers with their perimeter setups. But they must be doing something right because I have heard nothing but praise for the Firebolt and Lightning in regards to their handling.

Hi Everybody,
it’s always nice to read comments on “the kneeslider” because I can read opinions of people who really rides and work with motorcycle.
In this project I tried to rethink about motorcycles from the beginning, I really wanted to design something far from conventions but still “on the ground”.(no wings or magnetism flights) That was the challenge.
I agree with most of you about the hub motor today, but in my opinion in 5 to 10 years the tech spec of electric motors will be very different from now, different materials will be experimented and weight will be reduced, the same will be for the swing arm torsion and so on. Nothing to say about the riding position, but who knows how you’d better sit with this strange wheels??
What you are seeing and writing about is just a vision of the future from a designer who believe that humans will always race and will always take risks to be the first.
The big deal will be to increase the emotional and the ecological factors.
Thank you all for spending time to discuss on my work.
