Learn how to replace the axle set on your Strider balance bike with this step-by-step guide. Includes tips, common mistakes, and what to check.
Quick Answer
To replace the axle set on your Strider balance bike, you'll need a new axle set (one per wheel), a wrench, and a few minutes. Follow the steps below to remove the old axle and install the new one securely.
Why Replace the Axle Set?
The axle set is a small but critical part of your Strider balance bike. It holds the wheel in place and allows it to spin smoothly. Over time, axles can bend, rust, or wear out, especially if the bike is frequently used outdoors or in wet conditions. Replacing the axle set restores proper wheel function and prevents wobbling or uneven wear on the tires.
The Strider axle set fits all Strider 12” Ultralight Wheels. It includes two acorn nuts, two tabbed washers, two flat washers, and a rod to hold the wheel in place. If you need to replace the axles for both the front and rear wheels, you will need to order two axle sets.
Step-by-Step Replacement Process
- Gather Tools and Parts: You'll need a new Strider axle set (part number 603803), a 10mm wrench (or the appropriate size for your bike), and a clean work surface. Make sure the bike is on a stable surface and the wheel is off the ground. Check that you have the correct axle set for your wheel size—this set fits 12” Ultralight Wheels only.
- Remove the Old Axle: Loosen the acorn nuts on the existing axle using your wrench. Slide the wheel off the frame, then pull out the old axle rod and washers. Keep the old parts aside for comparison. If the old axle is bent or rusted, dispose of it properly; don't reuse it.
- Install the New Axle: Insert the new axle rod through the wheel hub. Place a flat washer, then a tabbed washer on each side, with the tab pointing toward the frame to prevent rotation. Slide the wheel into the frame dropouts and hand-tighten the acorn nuts. Ensure the tabbed washer's tab fits into the dropout slot to stop the axle from spinning.
- Tighten and Check: Tighten both acorn nuts evenly with your wrench. Spin the wheel to check for smooth rotation and ensure there's no side-to-side wobble. The wheel should spin freely without rubbing the frame. If the wheel wobbles, loosen the nuts and re-center the wheel before retightening.
Product Facts
