How to Choose the Right Kids Bike

Pick the wheel size and fit that matches your child now, and gives room to grow.

  1. Start with wheel size: This model comes in 12, 14, 16, and 18 inch wheels, each aimed at different age ranges.
  2. Measure inseam: Have your child stand and measure inseam. Compare that number to the saddle height range to make sure feet touch the ground.
  3. Check braking options: Look for bikes with both handbrake and coaster brake, so kids can learn braking by choice.
  4. Consider durability: A sturdy steel frame and enclosed chain guard reduce maintenance and keep little riders safer.
  5. Training wheels or balance: Removable training wheels make the first rides easier, then come off to encourage balance and confidence.
