Hoofddorp Barn, BSA folding Bicycle

[Bill Miller]

HI Keith, sounds like you have a BSA Mk.IV. Unlike the folding bike it came with push rod brakes and the westwood rims (concave profile). I have never ridden a bike a with that type of brake (not at all common in North America) but supposedly it is pretty effective brake system and easy to adjust/repair. Though issued in WW2, I believe the Mk.IV design dates back to the First World War, maybe earlier? Push rod brakes fell out of favour some 50 years ago.

Are you sure it uses a 28" tire? The Airborne bicycle that Alex and I have uses a 26 x1 3/8? I know that 28" tires & tubes while scarce, can still be had as last year I restored 28" rims on another bicycle I have.... getting 28" rims/spokes and rear hubs... that's another matter.
