I dunno about elsewhere but in Ontario the legality of a bike being on a sidewalk is based on wheel diameter to permit kids bicycles. So there ends up being kinds of adult bikes with intentionally tiny wheels, and it creates a real menace to pedestrians. Some municipalities also have age restrictions to combat this.
What are the more legitimate reasons for little wheels on bikes? I guess the goal like with this one is to have the least amount of bike as necessary?

There is no Ontario-wide law, per the Highway Traffic Act, §185(2):
> (2) The council of a municipality may by by-law prohibit pedestrians or the use of motor assisted bicycles, bicycles, wheelchairs or animals on any highway or portion of a highway under its jurisdiction. R.S.O. 1990, c. H.8, s. 185 (2).

Nothing about diameter/radius.
Naturally, Ontario is just Toronto and London.
Yes. Hence the folding.
