What is the minimum legal distance (altitude) to fly VFR under a Class B

Whatever the floor is.

CLE has a 1900 ft floor at the north side by Lake Erie and I
have flown at 1800 to go around CLE.

You could fly it at 1900. Hit a bump and go to 1901, however, you're illegal, but the
controller won't know it. The typical mode-C transponder reports altitude in 100'
increments and changes readings at about the 50' level; that is, at 1949', your
transponder should report 1900' and at 1950' it should report 2000'.

Dunno about you, but my encoder isn't that accurate. Still, it won't be precise
enough to get me busted at 1' over the floor.
