Here's my new-to-me folder.
It's a
Halfords Freewheeler from around 1980.
Good bits: it has new tyres, brake blocks and folding pedals; seatpost is not stuck. There is no rust. it cost £25.
Bad bits: I haven't checked the 3 speed gears. Steel rims. The seatpost is very odd - its diameter seems to vary. It has cotter pins.
