Two removable training wheels keep new riders steady while they find their balance. As your child grows more sure of themselves, you can take the wheels off and let them ride solo. It is a gentle path from wobbly first tries to proud independent laps.

The dual brake system gives little hands more than one way to slow down. A hand brake with a shorter grip distance is easy for small fingers, and the rear coaster brake lets kids stop simply by pedaling backward. That extra layer of control brings real peace of mind.

The solid metal frame stands up to daily riding, tip-overs, and driveway adventures. Durable rubber wheels roll smoothly over wood floors, brick, asphalt, and cement. A fun bell, anti-slip grips, and non-slip pedals round out a bike made for real kids.
The right fit matters more than anything, so measure before you buy.
- Measure the inseam: Have your child stand and measure from the floor to the crotch. Match that number to the saddle height so their feet can touch the ground while seated.
- Match wheel size to age: This bike comes in 12, 14, 16, and 18-inch wheels covering ages 3 to 8. The 12-inch suits kids roughly 31.5 to 41.3 inches tall, while larger sizes carry taller riders.
- Look for real brakes: A hand brake teaches proper braking habits, and a coaster brake offers a simple backup for beginners. Having both is ideal for young riders.
- Plan for training wheels: Removable training wheels let a nervous rider start steady and progress at their own pace. Choose a bike where they come off easily when your child is ready.
- Check the weight limit: This model supports up to 145 pounds, so it can comfortably last through the years your child fits the frame.
What age and height is the 12-inch bike best for?
The 12-inch size fits kids about 3 to 4 years old and 31.5 to 41.3 inches tall, with a saddle height of 19.5 to 20 inches. Always check your child's inseam against the saddle height to be sure their feet reach the ground.
Can the training wheels be removed?
Yes. The two training wheels are removable, so you can leave them on while your child builds confidence and take them off once they are ready to ride on two wheels.
How does the braking work for young riders?
There are two brakes. A hand brake with a shorter grip distance is easy for small hands, and a rear coaster brake stops the bike when your child pedals backward.
Does it come assembled?
The bike arrives about 95% pre-assembled with the needed tool included, so you only have a few simple steps to finish before your child can ride.
How does the seat adjust as my child grows?
A quick-release lever lets you raise or lower the seat without extra tools, so the bike keeps fitting as your child gets taller.
How do shipping and returns work?
We ship from a US warehouse with free US shipping on orders over $100, and offer 30-day returns. If you have questions, our human customer support team is here to help.
