These push buttons fit most Micro 2-wheel scooters. They are the same diameter, so you can pick the colour you like best.

Assembly instruction: Use a bahco or suitable size wrench. Move the steer to a 45-degree position backwards and tighten the push button.

Also check whether the pins in the folding block still go in and out  smoothly. If desired, spray some WD-40 to the pin and in the hole at the back, then move the pin back and forth 10 times.

PLEASE NOTE: Not suitable for the Micro Suspension and Micro Light
