Once you know the advantages you'll ask why not: effortless pedalling up hills; no-sweat commuting - literally; greater acceleration and so greater safety; and, ever-increasing battery range, with some models achieving 70km plus. ''Electric Bicycles'' covers all aspects of this rapidly growing form of transport and leisure riding, with chapters on history and development, classic models, choosing and using and much, much more.
