Otherwise the 1982 second edition is available second-hand for under a fiver, at which price it's worth a punt. Tbh the third edition is mostly the second ed with a couple of extra bits stuck on rather than a rewrite; OTOH the older material is still mostly valid, even if there are probably newer references available.
Huh, sure there was one on eBay for under that last night. This copy on German Amazon's about a tenner: https://www.amazon.de/gp/offer-listing/0262731541?condition=used&tag=bf-de-b-21

On that note, Archibald Sharp's Bicycles and Tricycles is from the 1890s, but is still worthwhile for its description of basic cycle engineering mechanics (see e.g. the pages reproduced here: https://www.peterharrington.co.uk/blog/archibald-sharp-the-greatest-of-the-victorian-bicycle-engineers/ ) . It's available in any number of cheap reprint editions.
