To be a little more specific and clear:
all the accessories that you added after purchasing the bike, i.e.
stuffs that were not on the bike when you bought the bike. This should be less ambiguous now.
(Since it didn't come with the bike, it's likely it's not absolutely necessary. In case you bought a bike that did not have, say, a seat, and you bought a seat for it, then that does not count, because the seat is necessary.)
