Sorry Dr Sam, but your pun makes it sound like it is not a Bike but rather a Railway Train we are dealing with - you know, one of those ought-to-be-obsolete, primitive machines that a certain kind of boy plays with models of; an ancient mode of travel that some slightly more grown-up little boys, in places like the House of Clowns or the Senate (after the Seniles that sit there!) seem to want to preserve, and try to force travellers to use still, despite the sad fact that they never go from where one actually is to where one wants to get to, and never ever go at a time one would like to have travelled, and that charge far too much for a fare, and often don't even provide a seat so the passenger has to stand the whole way, despite the ridiculous fare charged.
