I don't quite see the difference between metal spokes rotating at moderate RPMs and metal loops rotating at moderate RPMs.

  Spokes must have a much bigger cross-section than those loops, making them less likely to cut you. Otherwise the loop wheels would be WAY heavier.

  Imagine a cyclist riding into someone's leg with one of these wheels vs. a spoked wheel.
