I snapped a few pictures of bikes on a recent trip to Taiwan. Folding bikes seem to be fairly popular. The bike that I found most interesting was the "folding triple". This bike looked about the same size as your typical Dahon-type folding bikes in the US. However, it had seats for three. The "adult" rode in the middle seat and reached the far handle bars. A front child seat had a near set of handlebars, and a heavy cushion was on the rear seat for another child (or adult - these must be good racks!)
I did see a mother with her two kids cruising on one of these to the train station. This one looked fairly rusty and had smaller-than-usual wheels. But, they still managed to move at a reasonable pace. (Though they did seem to have a wobbly start.)
The area around the university was loaded with bikes. I saw the train station with its double-decker bike parkers first:
Then I noticed a few bikes around the corner towards the back:
And then it was on to biketopia. The number of bikes parked in close proximity would put Stanford to shame.
