I only spent one night in Amsterdam last year and in the 10 or so hours that I was there it felt like I encountered more bicycles than I had in my entire lifetime (a teeny bit of an exaggeration but you get my point). Now I'm in no position of authority to comment on Cape Town's bicycle culture, I don't spend nearly enough time in the city centre, but I think it's slowly catching up to that of European cities.
Cycles Lady is run by Moscow native and photographer Alena Chendler and is a little side project of hers where she documents all the stylish ladies on bicycles around her city. I definitely think Cape Town needs something like this. Maybe we have something similar already and I just haven't heard about it?
