How to Replace a Locking Button and Spring on a Scooter Handlebar

Quick answer

Replace the locking button and spring on your Micro Kickboard scooter handlebar by removing the old parts and installing the new ones. This fixes a loose or unresponsive folding mechanism.

Step-by-step replacement

1. Step 1: Remove the old button and spring: First, fully extend the handlebar to its tallest position. The locking button should pop out. If it doesn't, gently pull it out with pliers. Once the button is out, you can slide the spring off the handlebar tube. Be careful not to lose any small parts. If the button is stuck, apply a little penetrating oil and wait a few minutes before pulling.
2. Step 2: Install the new spring: Slide the new spring over the handlebar tube, positioning it so it will sit against the locking button. Make sure the spring is oriented the same way as the old one (usually the wider end goes against the button). Check the spring orientation before sliding it on; reversing it can prevent the button from locking.
3. Step 3: Insert the new locking button: Push the new locking button into the hole on the handlebar until it clicks into place. The button should sit flush with the handlebar surface. Test the folding mechanism by raising and lowering the handlebar a few times. If the button doesn't click in, the spring may be misaligned. Remove the button and spring, adjust, and try again.
