Busy bees and budding riders will love REI's Novara Stinger 16 in kids' bike, thanks to its removable training wheels, intuitive rear coaster brake and fun styling.  Sturdy high-tensile steel frame is almost as tough as they are and is designed to stand up to demanding use.  Rear coaster brake is easy and intuitive to use; simply backpedaling engages the brake.  Removable training wheels and built-in full-length chainguard help kids learn to ride without fear of tipping over or catching pants in the chain.  BMX-style handlebar is comfortable and fun; pads enhance safety and the front mud guard helps keep things clean.  Convenient handle is integrated into the back of the saddle for easy carrying or control
