Actually, the bike came with "your" FanFest-ticket - its a bonus/reward for those who are visting the FanFest.
So, this mount didnt went on the mogstation straight away, its there as a courtesy for all the people who cant/dont want to attend one of the FanFests but still want the bonus ingame item that comes with the tickets.

But obviously SE cares about money - they're a buisness, not a non-profit that cares only about our wishes and well-beings.
I'm not a fan of the mogstation myself (and I got the mount because I purchased a ticket for the FanFest in Paris, that I'm very much looking forward to), but I'm also not a fan of people whoe crying and cicking each time they put something on the mogstation, without educating themself first and while ignoring the mounts/pets/glamour we are actually getting ingame for our sub-money.
One could get the impression that all those (optional) items are only on the mogstation now, when thats clearly not the case - we're still getting mounts, minions and glamour ingame and sometimes there is even a reason why stuff is in the mogstation rather than right in the game, promotions like this one or the butler/maid-outfit amongst them.
