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.
Chipped Paint
Chipped paint or minor gouges on the bike frame are typical on CPO bikes. Excessive chipped paint will likely result in the bike being rated as “gently used” whereas no chipped paint or minor instances may result in the bike being deemed “like new.”
Scratches and Blemishes
Minor cosmetic abrasions, such as scuffs or small scrapes on the frame, are commonplace among CPO woom bikes. Rest assured, each bike is assessed by our team of professionals to guarantee no structural damage to the frame.
Worn Components
Obvious visual wear and tear on the componentry is to be expected on CPO bikes. However, after a thorough inspection, any parts that are not roadworthy are replaced. Example: flat tubes, balding tires, fully worn brake pads, etc.
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.
