With an adjustable seat and handlebar, this bike keeps up as your child grows across the 3 to 8 age range. Choose the wheel size that fits their inseam now, and enjoy plenty of room to raise the saddle as legs get longer.

A hand brake with a shorter grip distance makes braking easy for small hands, while the coaster brake lets kids pedal backward to stop. Together they give new riders more control and give you peace of mind.

Two detachable training wheels keep the bike balanced while your child learns, then come off when they are ready to go solo. Premium rubber tires grip sidewalks, driveways, and park paths for smooth, steady rolling.
The right size is about your child's inseam, not just their age, so they can touch the ground and feel secure.
- Measure the inseam: Have your child stand against a wall and measure from the floor to the crotch. Compare that number to the inseam range for each wheel size.
- Match saddle height: Your child should be able to touch the ground with both feet, especially while learning. Check that their inseam falls within the listed saddle height range.
- Pick the wheel size: This model comes in 12, 14, 16, and 18 inch wheels covering roughly ages 3 to 8. Sizing up too soon makes balancing harder, so choose for who they are today.
- Consider training wheels: New riders benefit from the two detachable training wheels for stability. You can remove them once your child builds balance and confidence.
- Check safety details: Look for an enclosed chain guard, anti-slip pedals, and easy-grip handlebars, all of which help small riders stay comfortable and protected.
How do I know which size to order?
Measure your child's inseam and match it to the size chart. The 12 inch fits inseams 17.5 to 20 inches, 14 inch fits 19.5 to 21.5, 16 inch fits 21.5 to 24, and 18 inch fits 23.5 to 25.5 inches.
Does it come with training wheels?
Yes. Two detachable training wheels are included to keep new riders steady, and they can be removed once your child is ready to ride on two wheels.
How much assembly is required?
The bike arrives largely pre-assembled for a quick setup. A user manual is included, and most parents finish the final steps in a short time.
What brakes does it have?
It has both a hand brake with a shorter grip distance for small hands and a coaster brake that stops the bike when your child pedals backward.
Does the kickstand come with every size?
No. The kickstand is only available on the 18 inch bike. The smaller sizes rely on their training wheels while your child is learning.
How do shipping and returns work?
This bike ships from a US warehouse with free US shipping on orders over $100. We offer 30-day returns and real human customer support if you need help.
