This Certified Pre-Owned (CPO) model is ready for a new home. All CPO woom bikes are Certified Roadworthy by our bike technicians and then rated as “like new” or “gently used,” depending on a holistic assessment of the bike’s condition.
Both classifications of our CPO bikes have been fully quality-checked for safety (i.e. grips, brakes, steering limiter, tires, saddle, kickstand, and wheels) and adjusted accordingly. Parts are replaced as needed to ensure a safe riding experience for your child. Each bike may come with its own quirks—think blemishes to the paint—but is nonetheless ready for the road.
Certified Pre-Owned woom bikes with a “Like New” rating exhibit no signs of outdoor usage. They may have been assembled, but contain no visual indications of extensive riding. Paint, grips, saddle, and tires all appear in good condition.
All Certified Pre-Owned (CPO) bikes are final sale. While each CPO bike is non-returnable, our qualified Customer Service team is ready to assist with any questions or concerns post-purchase.
