Strider put together all the right ingredients to give your tyke a taste of confidence to successfully shift from riding a balance bike to pedaling like a pro as quickly as possible. The 14x starts off as a balance bike, which helps kiddos who either haven’t been on a bike before or are veteran Strider riders gain confidence and balancing ability on a bigger bike. Once your little renegade is ready to pedal, just attach the Easy-Ride Pedal Conversion Kit (sold separately) and you've suddenly got the most adjustable, most amazing pedal bike in the world. As your little one grows, the adjustable seat and handlebars will continue to fit them. Converting the 14x from balance bike to pedal bike is super quick and easy (wrench included).
