Some people hold up Amsterdam and Copenhagen as great models, but all I see are miserable looking cyclists on 50 pound city bikes in bike lane traffic jams. China is certainly worse, adding in the pollution and the even greater numbers. I remind those who may be interested of the drawbacks, including exposure to the weather, sweating, crashing, flat tires, etc. None of this stuff bothers me, but are "no gos" for the average person.
