In Patch 11.0.5, players can earn a Fel Reaver Motorcycle mount during the 20th anniversary event!
Blizzard has added two Fel Reaver Motorcycle mounts to the mounts database file in the initial Patch 11.0.5.
20th Anniversary Event Mount?
The mount you can get form the 20th anniversary event is called 
Incognitro, the Indecipherable Felcycle. It has existed in the game files for quite some time, but only now, Blizzard added the mount as an entry to the associated database file.
Upcoming Promotion Mount
The second mount added in 11.0.5 is 
Hateforged Blazecycle and the current source says it will be available via a Promotion. No further details beyond that have been specified, and we can only guess where it will come from!
