Yes, that's the assembly 73537.
I couldn't verify exactly, but seems this was made from 1985 to either 2001 (Metroliner Re-Release) or 2007 (Cafe Corner).
There were also a couple Educational/Dacta sets with bicycles during that era, but since those even changed motorbikes for trikes (amongst other parts), I wouldn't count these as "reliable source".
The wheel indent sounds logical - I assume then this is 33485/4719(b) from 2009 (First seen in Set 7639)?
