We goggled at a concept 39er bike just a few weeks back, but DirtySixer make actual 36er bikes for very tall riders. Such as, Shaquille O’Neal:
They’re currently running a Kickstarter campaign, which is already fully funded.
The reason they’re using 36 inch wheels is proportionate sizing for tall riders. Shaq riding a 27.5 wheeled bike would probably look a little like me riding the bike of a small child, or Barney on a 26er (proportionate wheel sizing is the very reason Barney wants to throw 26 inch wheels in room 101). They’re not weeny rims either, 36 inch ones usually hail from mountain unicycling and a single rim will be designed to take the whole weight of a (average-ish) person by itself.
Of course, up (down?) to a certain point tallness isn’t obligatory for riding a 36er. You might just want to go up stairs:
