I wonder if you could actually make money providing secure bike lockers, shower, maybe snacks or something
Probably not 10 years ago, but presumably (and I'm not being factious) the installation of some $10 million worth of bike lanes brings exponentially more bicycles into the downtown core as people cash in on our somewhat mild weather (at least "mild" in cycling terms).
I'd pay for the perks in your post, if it was offered.
The only negative might be the high cost of square footage in the downtown core, which tends to lend support to the concept of the COV offering flat, covered, staffed, somewhat secured parkade space ... even if they offered that space through a private business - the "PPP" formula as it were... but applied to a very secure cycling facility with showers and change rooms.
