Just spending a few days in Copenhagen on business and have been impressed with the amout of bikes in usae. Bikes every where and of all shapes but mainly 28" wheel. Interesting to note the amount used for commuting, more so than I've seen in London, nice wide and safe cycle paths make it easy to get about. Many bikes seem to be upright giving a relaxed cycling style, very few 'racer' types and only one or two mountain bikes. All seem to use rigid forks and lots and lots of womens bikes in use, maybe more than mens or at least parity. Also like the use of axle mounted LED flashing lights activated by rotating magnets. Just found a really old Kalkholf, no locks but still in active use it seems. No sign of an E-bike though.
