Here is David at a typical Bixi station.
And here he is on the Bixi bike. The seats are adjustable up and down, and there are front and rear lights that come on as soon as you start riding. There is a little basket-type thing in the front with a bungee, so you can put your bag there.
And now, David is at another Bixi station!
The stations are very close (only a few blocks apart), so in the section we were, it was always easy to find a Bixi station. Bixi seems to solve some of the problems of mass transportation, so here's hoping it catches on, and maybe we'll see Bixi's in other cities!
