    Default Interesting development for bicycle wheels

    Obviously not for competition level but interesting development none the less.

    It looks good.

    But ... People have been reinventing the wheel since the first person used a fallen tree trunk as a roller. Some of the reinventions catch on, most of them don't. Anyway, I'm sure I've seen a variation of that idea before.

    What an irritating tit he was.

    Nice idea, but i'm guessing it'll be more expensive, so people probably won't pay to 'upgrade' as they'll be happy enough with what they've got. Wonder if they'll work with 'larger' rims? Guessing that the majority of bikes have larger rims than the test bike.

    In true dragon's den style. I sighed when the inventor announced that he'd ploughed 'ALL' of his money into the development. Hence the need to ask the public for money.

    But I'm no expert so may well be the invention of the century (but i won't be holding my breath, maybe jml will pick it up)

    The wheel as a self contained flexible unit makes sense, but its the lateral movement I think causes the problem. But on city commuter bicycles for your average cycling Joe I think that could work very well.

    As I said, people have been reinventing the wheel for millennia. The "new" wheel looks like a development of this idea from the 30s: Latest Developments in Automotive Field | Modern Mechanix

    It's CNN so it's probably just pandering to what the yanks expect all Brits to be like.

    That wheel seemed to be all over the place and it also seems limited to small rim size, any bigger and they'd need to re design the thing. Nice idea but I don't see that chap making any of his money back.

    Yes, any larger diameter and the flat spokes would have to be correspondingly wider. My seat of the pants guesstimate is a non linear, almost exponential scaling, so double the diameter, four times the width required sort of thing. It already looks wobbly even at the smaller diameter.

    It has also just occurred to me, with a larger diameter there is a much bigger unsupported span for the rim. Even this small rim must be a LOT stiffer than a spoked rim needs be because otherwise if you bump it up a curb, it will buckle in the gap between mounting points. A large rim would need to be unfeasibly strong from a cost perspective.

    Thing is, these kind of inventions tend to go round in circles.

    I don't have any problem with spokes tbh, reliable enough, easy & cheap to fix. It's rather late in the day to be finding solutions for that 'problem' of riding over cobblestones FFS.

    as someone said a normal spoked wheeel works by keeping area either side of the impact in place and this doesn't really have that. given that this would seem only suitable for brompton type bikes, and how light, strong and quick their wheels are i'd be very surprised if this took off

    Weeeelll....with my seat of the pants thinking here, I don't believe that's true.

    A normal wheel loads the spokes only in tension, indeed you can make a bicycle wheel with string spokes. The very fist ones were string spoked AFAIK. Therefore they don't offer any support to the area of the rim which gets walloped when you hit a curb.

    The bigger concern with this funky wheel would be fore/aft/otherwise radial float of the hub relative to the rim I woulda thought.
