Rose, I prefer my Sturmey Archer gears on my 20 year old bike [I bought in Belgium]. In the early 1950s, my friend got a bike and had Sturmey Archer gears which were very impressive. Here are the gears: sturmey-archerheritage.com How much drag is there on the continuously variable bike? I'd have thought the drag from squashing and pumping fluid would get annoying, but perhaps it's trivial compared with other losses. I wonder how often the oil needs changing and how much wear there is on the balls. It looks as though it could be very good. Continuously variable gears would be nice. Beijing is a great place for bicycles, apart from the dirty air. There are so many bicycles there, you can get traffic jams of them. It's flat, which is nice on a bike. Mqurice
