>I fixed about 3 broken spokes per year. Almost always on the drive side of the rear wheel. This hints at one less obvious advantage of the drive system described in the article: no need for asymmetrical wheel dishing. Rear wheels for conventional derailleur systems have to be built asymmetrically[0]. This makes the wheel weaker than a symmetrical one, because the drive side spokes are under higher tension. I ride a hub gear bicycle with symmetrical wheels as my primary form of transport and I've never broken a spoke. Electric drive would allow the same wheel strength.
