Quoting rowman :
the want of a better name a bike. What is it about Cambridge that leads
the average cyclist to never use oil, change brake pads, make any
attempt to look around at road junctions

Anywhere in Cambridge is ten minutes away by bike and during most of those
ten minutes your speed will be limited by factors other than the
efficiency of your machine.

and never wear a cycling helmet?

Because they have the wit to know the things aren't any good.
