20 Inch
From WikiPedalia
There are two common "20 inch" wheel sizes:
- ISO 406 mm - 20 x [decimal] This is the common size used on most BMX and folding bikes, many recumbents.
- ISO 451 mm - 20 x [fraction] -- used on non-folding Raleigh Twenties, British juvenile bicycles, and sportier folding-bike models from Bike Friday and DaHon.
