Man, that's nasty - not sure I'd have the resolve to take that route tbh!
Ahh yes; I've found a couple of those too. Didn't know it was a thing until I found one and googled it..
Following this evening's ride this post appears particularly timely. I decided to treat myself to a beer; the first off-license I visited was departed empty-handed thanks to their incorrect / extortionate pricing, so I journeyed further across town and scored a few treasures on the way.
Firstly we had a nice fully functional Clipper lighter (I usually keep these even if they don't work as they're usually serviceable) - always useful for a variety of fire-based tasks. Next up was another probable smack-chariot; a nice (if of gas pipe construction) old ten-speed steel Raleigh road bike.. abandoned because it'd been ridden until the rear tyre literally disintegrated and jammed the rear wheel by interfering with the brakes
Tomorrow's job will be to give it a closer inspection and check the frame number against the Bike Register website. If I don't get any hits I'll look towards fixing it and either keep it as a pub bike or punt it on.
I also went back for a second serving as I'd seen another abandoned cheapo hybrid that looked worth fixing. Unfortunately the chain was stuck between the cassette and spokes, attempts to sort it on the spot failed and I managed to wheel it for about half a mile before it jammed completely and I grew tired of looking reet shifty to passers by so left it for someone else to "enjoy"..
A good score nonetheless
