Durable pneumatic tires roll smoothly over sidewalks, driveways, and park paths for a steady ride. The two included training wheels give beginners the balance they need while they build confidence pedal by pedal.

Grows Alongside Your Child
Grows Alongside Your Child

The height adjustable handlebar and seat mean this bike keeps fitting as your child gets taller. On the 16 inch size, the seat adjusts from 21.5 to 25.5 inches, so it works for many riders ages 4 to 7.

Two Ways to Stop Safely
Two Ways to Stop Safely

A hand brake sized for small hands pairs with a coaster brake for reliable stopping in any situation. A fully enclosed chain guard keeps little fingers and pant legs away from the moving chain.

CPSIA Certified
Meets CPSIA safety standards with an enclosed chain guard to protect curious little hands.
Adjustable Fit
Handlebar and seat raise as your child grows, extending the years you get from one bike.
Mostly Pre-Assembled
Arrives largely put together, so setup at home is quick and labor-saving.
Soft Padded Seat
A cushioned saddle keeps longer rides comfortable for growing riders.
How to Choose the Right Kids Bike

The right size and features make the difference between a bike your child loves and one that sits in the garage.

  1. Measure by inseam: Have your child stand and measure their inseam, then compare it to the bike's seat height. They should be able to touch the ground while seated for safe starts and stops.
  2. Match wheel size to age: Wheel size matters more than age alone. This 16 inch fits suitable heights of 41.5 to 51 inches, roughly ages 4 to 7, while 12 and 14 inch bikes suit younger, shorter riders.
  3. Look for training wheels: Removable training wheels let beginners build balance at their own pace. Note that the 20 inch size does not include them, since it is meant for confident older riders.
  4. Check the braking system: A hand brake teaches modern braking habits, while a coaster brake offers an easy backup. Both together are ideal for new riders learning to stop reliably.
  5. Consider extras that matter: A storage basket, chain guard, and adjustable parts add real value. Keep in mind only the 18 and 20 inch sizes include a kickstand.
Frequently Asked Questions
What size child fits the 16 inch bike?

The 16 inch bike suits a height of 41.5 to 51 inches, roughly ages 4 to 7. The seat adjusts from 21.5 to 25.5 inches, so measure your child's inseam to confirm they can reach the ground.
