Seconding the Penguin Book of the Bicycle - witty, erudite, and humane. Also the Seaton. I enjoyed Bella Bathurst's _Bicycle Book_ a lot - it describes the joys of riding a bike well, and has a section on the building of her custom frame (the builder being Dave Yates OTP).
Some academic history:
*Paul Rosen's _Framing Production_ (MIT Press) is about the rise and fall of Raleigh, so Nottingham rather than Coventry. I remember it being quite dry, but probably worth a look.
*_The Social Construction of Technological Systems_ (eds Biker, Pinch, and Hughes) is a classic in the history and sociology of technology (MIT Press has a 20th anniversary edition paperback), and one of its case studies is on the bicycle's evolution from high-wheeler to safety, and how this affected the social groups that interacted with it.
*The first chapter(s?) of Hugh Driver's _The Birth of Military Aviation: Britain, 1903-1914_ are about the growth of Midlands manufacturing and the Bicycle Boom; early car and aircraft manufacturers were set up by the same socially elite types that had been at the forefront of the bicycle boom. It's been years since I read it, but I do remember it having a fair bit on Coventry. At fifty quid though (go go academic monograph pricing!), you may want to try and track down a library copy.
