I think the problem of removing the rear wheel with IGH hubs is exaggerated. Each has a very specific but simple way to disconnect the cable or cables, it just has to be learned. You do need to carry a wrench in your kit since they're not QR. I could do it when I was 8 with an SA 3spd,and now that I am...ah...more mature,I can do it with a Nexus or Nuvinci hub. They're just not QR.
