This owner’s manual contains details of your Flyer™ kids’ bike including instructions 
for assembly, operating, and maintenance. To ensure safe use and prevent injury, 
please carefully read all information in this manual before use. Take time to familiarize 
yourself with your Flyer™ kids’ bike before use.

While this owner’s manual is meant to introduce you to your Flyer™ kids’ bike, it is 
impossible to guide owners on every possible scenario when using a bicycle. There 
are inherent risks using any bicycle and it is the owner’s sole responsibility to ensure 
safe riding. Always take responsibility for you and your child’s own safety.

Please keep this manual for future reference. If you have any questions about your 
bike, contact the Radio Flyer Customer Service Team. Our award-winning service 
team is committed to providing you with world class support, right from Chicago.
