Erm hate to say... there’s stairs for building code reasons and elevators for accessibility reasons. They’ll forever exist. Interesting concept, but no one will want to bike down a building on fire or when they have no legs.

You're going to have to have same numbers of stairs & elevators for OH&S, emergency & disinterested/unfit/disabled users anyhow Nice idea. Never going to be installed widely. Just adds to maintenance costs to keep a few adrenalin junkies happy
