Buying kids' bikes as they grow can get expensive. This GYMAX 4-in-1 trike solves that by growing with your child from about 2 to 4 years old. It cleverly converts between four modes: 1) A push trike where you control it with the adjustable handle, 2) A standard kids' tricycle, 3) A baby walker for support, and 4) A balance bike by removing the pedals. The seat height has two settings (33cm and 37cm), and the handlebars can be turned for easy gripping. Safety features include a 135° steering limit to prevent sharp, risky turns, and anti-skid handles. The EVA wheels are quiet, shock-absorbing, and work on various surfaces. The carbon steel frame is sturdy and holds up to 30kg. Assembly is pretty straightforward. A fantastic, versatile gift that provides years of play and development.
