How to Choose the Right Kids Bike

Focus on fit, braking, and confidence when picking a first pedal bike.

  1. Measure Inseam: Have your child stand barefoot and measure from crotch to floor, then compare that to the bike s saddle height. Aim for a fit that lets the child touch the ground with toes.
  2. Saddle Height Range: This 12 inch model offers a saddle height of 17.5 to 20 inches, suitable for many 3 to 4 year olds. Choose a bike you can raise as your child grows.
  3. Training Wheel Option: Training wheels help build confidence and balance, and should be removed when your child can coast and balance independently.
  4. Brakes and Control: Look for a hand brake sized for small hands, plus a coaster brake as a simple backup. Practice braking in a flat, safe area before heading out.
  5. Tire Type: Pneumatic, air-filled tires offer a smoother ride on sidewalks, paths, and grass. Consider tire type based on where you plan to ride most.
