How to Choose the Right Kids Bike

Start with fit and function, not just age, to pick a bike your child will use and enjoy.

  1. Measure Inseam: Have your child stand barefoot and measure from crotch to floor, then compare to the bike saddle height range.
  2. Check Saddle Height: Saddle height must allow your child to touch the ground with feet for safe starts and stops.
  3. Pick Wheel Size: Choose the wheel size that matches your child’s height and inseam, then use training wheels if needed.
  4. Look for Brakes: Dual brakes, hand plus coaster, help kids learn controlled stopping as their skills improve.
  5. Plan for Growth: Adjustable handlebar and seat keep the bike usable across seasons, extending how long your child can ride it.
