The Best Bikes of 2015-2016 >>>. There are plenty of ways to enjoy a warm spring afternoon, but riding a bike is one of the most active ways to spend your leisure time. According to NutriStrategy, a relaxing bike ride (<10 mph) burns more calories than an easy walk (2 mph)—281 calories versus 176 calories per hour. Challenge yourself by powering your way up hills and pushing your speed over 10 mph, but even keeping to a leisurely pace is a great way to supplement an active lifestyle.
