Question

Why do people with bikes still insist on taking them on trains in rush hour London? Surely bikes are to ride?

Answer 1

So they don't have to avoid the plonks in the cars who think they have an absolute right to the road, pushbikes be damned!

Answer 2

They are used to ride from the train station to home.

Answer 3

They are used to ride from the train station home.

Answer 4

Because a lot of them are too s****. to take a folding bike (which are allowed on peak trains)

Answer 5

Because, presumably, they use them to ride from home to their starting station, then from their London terminus to their place of work. But do the TOCs allow bikes on rush hour trains - I thought they'd stopped this practise?
