How to Choose the Right Size Bike

Wheel size and fit matter more than age, so measure and match before you buy.

  1. Measure Inseam: Have your child stand and measure inseam length from crotch to floor. Use the bike saddle height to confirm a comfortable, safe leg extension.
  2. Match Rider Height: Use the suggested ranges: 20 inch wheels suit about 48 to 60 inches tall, 24 inch wheels suit about 56 to 66 inches tall. If in doubt, choose the smaller size for easier handling.
  3. Check Brake Reach: Make sure your child can comfortably reach the handbrake with one or two fingers. Many kids benefit from the shorter reach design on this bike.
  4. Think About Terrain: If you plan to ride trails, choose the suspension and knobby tires for better control. For mostly smooth sidewalks, either wheel size works depending on fit.
  5. Plan for Growth: Look for adjustable seat and handlebar height so the bike grows with your child, extending usable years.
