Introducing Gyrobike’s Gyrowheel. Gyrowheel is a revolutionary front wheel for children’s bikes and is a better solution than traditional training wheels. Powered-on, Gyrowheel delivers high stability at low speed to help keep the rider upright. The rider learns correct riding technique and enjoys a safer, easier and faster learning experience. Plus, it’s more fun and effective than training wheels. Learning with Gyrowheel is less frustrating and more exhilarating for parents too! Watching a new rider enjoy the freedom of two-wheeling for the very first time is priceless. Gyrowheel is available in two sizes, 12 and 16 inch, and is designed to fit most standard kids’ bikes. Gyrobike also offers a complete 16 Inch Kids’ Gyrobike that comes equipped with Gyrowheel.
