I have been arguing with friends on this. Is it right to say 'go by a bus' or 'go on a bus'?

Either are quite understandable, and even grammatical.

Idiomatically one would usually say I shall go by bus (the indefinite article is out of place in this context).

In some situations if you wanted to stress that you were going by bus, as opposed to walking or some other transport mode, it might be appropriate to say I shall go on a bus (indef. article essential).

  • WS2 that help was great and i think i concur with you. I had not noticed the effect of using an indefinite article versus not using one. thanks a lot and God bless you. – Fred Odida Oct 20 '14 at 11:51

Using the preposition on is due to the fact that when a bus is on motion, one inside is on it but in it while it's not on motion. Going on a bus of course refers to a moving bus.
