I've only recently rediscovered cycling so my knowledge of bikes is rooted in my cycling days as a teenager - and books weren't very often on my activity list in those days. So....my knowledge of bikes is not only very rudimentary but, more importantly, is only about bikes as they were in the 60s - never mind electric bikes. While I know I can get lots of information on line (including youtube etc), I would really like to get a book that I can hold in my hands and flip through the pages. The question is...which one? Anyone have a recommendation? It needs to be up to date, to not assume I know anything about bikes but not be too techy (I'm just a casual cyclist) and, ideally, very readable.
