Julie Long May 7, 2014 07:46 PM Amazing. Daishi May 7, 2014 11:53 PM It's interesting how inventions spark at around the same time. Loopwheels and ShockWheel are also pretty recent. This idea would not have made sense back when bicycles still used rim brakes but tis possible with disk brakes mounted on the hub. I'm not a mechanical engineer but the biggest problem I see is that the outer rim must be made much more rigid to retain its shape without the support of rigid spokes or mags inside it. Even after that is factored if one of these shocks had just a slight difference in tension it would feel like driving on a bent rim because the hub wouldn't be purely centered. This would cause the effect of "high spots" and "low spots" almost like using a slightly oval wheel that would absorb some momentum. I think the net result is probably heavier than fork shocks with a lot more cost. The only real benefit I see is that it has potential to shock absorb in multiple directions but unless you smash into a lot of curbs and stuff vertical shock absorption seems fine. I see it as a gimmick that people might notice and point at as cool/different but I don't see it as an improvement over the existing design. SumoDes May 8, 2014 04:13 AM Good point there Daishi, Also there is another issue that will pop up during taking a sharp turn. The banking forces will try to induce axial force trying to incline the wheel.But nevertheless a beautiful idea,does have potential. Mel Tisdale May 8, 2014 05:59 AM SumoDes makes a valid point when they say that side forces will present a problem in keeping the wheel rotating in the same plane as the bike frame. This will become more pronounced as the suspension system loosens with wear. I am not at all sure that this is a sensible solution to the problem of shock absorption when one reads that it only comes into play "...when the wheel takes particularly big hits." A normal bike suspension operates on all surfaces, from the smooth to the "cor blimey." Seeing as you are asking for votes, mine goes to the Loopwheels design. It is simple, durable, low/zero maintenance, rigid outside of the designed plane of rotation and, I suspect, a lot cheaper. hawkinspeter May 8, 2014 07:58 AM This idea is completely retarded. When you are driving a wheel from the hub, you need the wheel to be as stiff as possible to transfer that energy to the rim and the tyre and thus propel you. If you try to put any kind of springs or dampening between the hub and the rim, then you are losing energy compressing/decompressing with every single pedal stroke. So, for only $2000 you can get overly heavy, poorly performing wheels that probably require a lot more maintenance than normal bike wheels. You'd be better off just putting a big cushion on your saddle. However, this idea can work well on a wheelchair as you are providing the driving power from the rim, so shocks between the rim and the hub won't be a problem. Just don't ever put these on a bike. wle May 8, 2014 12:52 PM these have been ''invented'' over and over again for at least 100 years. expensive weak heavy energy-wasting \no road bike needs shocks, period\ wle SLB May 8, 2014 01:00 PM SumoDes and Mel -- in normal operation, the wheels on a two-wheeler (unless it uses gyroscopic stabilization) don't experience much sideways force. There's a little bit when entering and exiting a turn, but during most of the turn, the bike's lean exactly compensates for its lateral acceleration. The force on the wheel is strictly radial. If this were not so, the bike would fall over! I agree, though, that the dampers in this design would have to be made to very tight tolerances. The advantage of using dampers over springs is that dampers can have a nonlinear response, where they don't move much at all up to a certain level of force; it's hard to do that with springs. These do seem to be a lot more expensive than the Loopwheels, though. Michael Logue May 8, 2014 01:05 PM Looks like another case of a solution looking for a problem....... Mirmillion May 8, 2014 01:37 PM Bound to be a little loopy after loosening up but a nice design nonetheless. Maybe best on small diameter or slower moving wheels where torsional play and centripedal forces won't cause a sort of self-steering phenomenon. I'd be happier if this design had used a spiral array of carbon fiber blades which flexed from any angle of impact but also provided protection against side forces due to high lateral rigidity. Bruce H. Anderson May 8, 2014 04:38 PM I wonder about the distance between the hub and the wheel, and what forces may be applied to the shocks. Longer distance equals greater forces. Loopwheels are 20" and made with folding bikes in mind. On the video the Softwheel doesn't look much larger so maybe it won't be an issue. Taller Loopwheels are a possiblilty, and Sam Pearce said he might have something new in 2014. I would favor the Loopwheels based on simplicity.
