This seems like it might work well for wheelchairs, where performance is not a large issue. For bicycles though, it's turning a component that was once static into one that's rotating. This means the rider will have to overcome a whole new set of forces just to get the wheel moving. There's a reason people pay such a huge premium for very light rims and tires, and go through the trouble of not having inner tubes.
- Someone 12y agoIs performance really not a large issue for wheelchairs? I would think the elderly would not have the strongest arms, and younger, powerful riders would in many cases prefer speed over comfort. Yes, it might be useful in rough terrain, but that is precisely the terrain where the loss of power due to inefficiencies in the wheel might mean the difference between getting over that bump or not getting over it. I think there is little room between this and just mounting (much) wider tires and using less tire pressure.
- lizzard 12y agoPerformance is a huge issue. A better performing wheelchair makes a difference in our independence and range we can go on our own. It also makes a big difference in the wear and tear on our shoulder joints and hands.
