Our new "Generation 3" PreWheelz packs a ton of changes for 2021. Starting with the re-designed, larger-sized, handle-equipped carton, this version comes almost fully assembled. It also features a lightweight, newly designed 6000-series alloy frame with a molded footrest platformas well as an all new one-piece bar/stem combination, further simplifying the assembly process. What traits does it share with its predecessor? How about the scuff-resistant tubeless tires, adjustable bar height, fully sealed hubs, high-impact mag wheels, and of course, our industry-leading limited lifetime warranty. PreWheelz by Haro; your child's gateway to fun and freedom.
