Book excerpt: Beer and bikes: can they ever mix? What's the best way to cycle in a summer dress? How much bike do you get for £70? Or £10,000? The Guardian bike blog is one of the most vibrant sections of the newspaper's website. Here, a cycling community from around the world gives their views, rants, complaints, and every clever tip available - from keeping warm in winter to beating the bike thieves. Along with brilliant advice there are also plenty of biking tales, from the sublime (a ride by moonlight on the summer solstice) to the ridiculous (the mysterious world of naked rides). Cyclebabble is the truest, funniest and most useful collection of cycling voices there is.
