Bikes: Nothing special, but it works.
Lots of them. I linve in New York City. There are thousands (actually, I have no idea how many there are, but there must be a lot).
They mostly ride fixies. Some ride single-gear bikes, track frames, but have a freewheeling single cog in the back and a front brake only. Often the frames are completely wrapped in old inner tubes. The seat is usually about a foot higher than the handlebars.
They're amazingly fast.
