woom 4 SRAM Certified Pre-Owned (Like New)

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.

As of the Fall of 2022 in the US, woom has transitioned from SRAM to microSHIFT components, just on our woom 4 bikes.  

Supply chain issues brought about by the coronavirus pandemic have resulted in limited bicycle component availability on a global scale. As a result, in 2022, we decided to switch to a suitable alternative for the future production of our woom 4 bikes. 

The microSHIFT groupset has a few minor differences from the respective SRAM components. While the previous SRAM groupset featured 8-speed gearing, the microSHIFT features 7-speed gearing. The overall gear range remains the same (both feature 11-28 teeth cassettes). 

With one less cog in the cassette, the microSHIFT groupset is lighter than the previous SRAM equivalent. The microSHIFT shifter also features crisper shifting, less chain travel, and offers more ground clearance than its SRAM predecessor. 

Whether you own an existing woom 4 with SRAM components or a newer woom 4 with microSHIFT components, rest assured that woom experts have carefully considered its functionality and compatibility with your child’s bicycle.
