1. Ensure the saddle is properly aligned with the frame (A in image below) and the stem and handlebar are properly aligned with the front tire (B in image below).

  2. Check the saddle height is correct and that the minimum insertion line on the seatpost isn’t visible.


  3. Nuts, bolts, and other fasteners: Ensure the bolts are tight on seat collar (C in image below), stem (D in image below), and wheel bolts (E in image below). Also ensure the secondary retention devices (safety washers shown in green below) are securely engaged in the frame and fork’s dropout holes. 

    You can check the tightness of the handlebar, stem, and seatpost by securing the balance bike between your legs and trying to forcefully twist the handlebar and saddle. It should take a significant amount of force to twist these components. If either moves easily, realign the part, check the bolt tension and try again. Repeat as necessary until there is no movement.

  4. Wheels: Ensure the wheels spin freely and are centered in the frame and fork.

  5. Tires: The tires must be inflated to 20-30 PSI. Periodically check and re-inflate the tires. 

  6. Headset: The headset and stem should be pre-adjusted and aligned out of the box. If the headset is loose or the stem is misaligned, please visit your Authorized Specialized Retailer.
