    Now this is one for the engineers amongst us Steve but I seem to remember reading that shaft drive bikes were heavier & lost efficiency to their chain driven versions.

    On the surface, it seems those belt-drive systems are pretty neat. I don’t know how practical they would be on a trike though, considering the distance from the front crank to the rear axle.

  3. This is more a shaft drive, don’t you think…? I had looked in to shaft driven bicycles a long time back, and at that time it was a design that was not in kit form but could be bought as a fabricated bike from a manufacturer.. Now there are kits made to up grade a bicycle, a little pricey, but made from aluminium and not to hard to put together… As for this design I think the concept to be pure, but worry as to the possibility of mechanical failure while on the road.. I mean what could ya do, it’s not like ya can go down the road a ways and find a replacement part on the shelf, you would have to call your trip, and go back to the drawing board and figure a new way down the road again… Right…? Well what the hell do I know…?

  4. Even hollow aluminum shaft drives are too heavy for the amount of torque a human being can produce. Plus, the supports for the bearings add more weight and complexity. I do like the folding mechanism, though.

    Aluminium wouldn’t never be my first choice for an drive shaft. A simple CroMo steel tube would be stronger at similar or even lighter weight. My first thought was to use carbon fiber tubes as drive shafts. It works in the wings of the Airbus A380 to move the outer flaps, for instance ;)

    Yep, I agree. Give me stainless steel or some other tough metal that will last several generations of human life! Lightweight drive shafts are of little use if broken in the middle of nowhere.
