Keep in mind that folding bike forks come in at least two different fork OLD (Overnut Lock Distance): 74mm and 100mm.
74mm wide wheels can be installed on 100mm wide forks with an adaptor, but obviously not the other way around.
Ditto for the rear. OLD can be 130 or 135mm. On steel frames it kinda won't matter as you can compress or expand the material 5mm, but this is a no-no on Al alloy frames.
