โš™๏ธ Tips for Choosing the Right Size

  • Measure inseam: The most accurate sizing is based on your childโ€™s inseam โ€” the seat height should allow the balls of their feet to touch the ground.

  • Adjustability: Choose a bike with adjustable seat and handlebar height so it can grow with your child.

  • Balance bikes: Great for toddlers under 4 โ€” they teach coordination before pedals.

  • Avoid โ€œtoo bigโ€ bikes: Itโ€™s tempting to buy a bike theyโ€™ll โ€œgrow into,โ€ but oversized bikes can be unsafe and discourage riding.
