When you were a kid, the first day of Spring-like weather probably meant it was time to dust off your bike and take a spin around the neighborhood. But we’ve come a long way from those carefree days. As cycling becomes more popular, especially in big cities, it brings with it some unexpected downsides, many of which Grant Petersen takes on in Just Ride, his book about opting out of racer culture and into enjoying your bike the way you did as a kid. Petersen is the founder and owner of Rivendell Bicycle Works, and a well-known figure in the bike world. His argument? “A lot of the advice you’ve been getting ever since you became a bike rider is flat-out wrong and is actually bad for your health.” Just Ride is against all of the following: helmets, carbohydrates, biking as a way to lose weight, and wearing silly riding outfits. Well, he’s not exactly against those things, but Petersen has some unconventional opinions about them. If you’ve ever ridden in the bicycle lane, rode in a charity race, or watched the Tour de France (or, as Petersen calls it, the BORAF, for Big Old Race Around France), you’ll want to read what he has to say. The book comes out in May, and until then, the Atlantic has an excerpt to tide you over.
