Its a buff from a quest
You can't play a goblin but you can raise the rep for them and get the trike.
quest reward form azhera
it's from an item called: faded wizard head you have a change to get goblin or any other race when you use it (30min cd, buff lasts 30min, dissapears with dead)
trike is avaible when exalted with blidgewater cartel wich you can bu the tabard off at orgri fp.
