Both the saddle and handlebar height adjust as your child gets taller, so the bike keeps fitting through growth spurts. That means more seasons of riding from a single purchase.title.set.

The removable training wheels give beginners the stability they need to feel safe. When your child is ready, take them off and let them practice balancing on their own.

A hand brake sized for small hands works alongside a rear coaster brake, so kids can stop quickly however they instinctively react. The fully enclosed chain guard keeps little fingers away from moving parts.
Getting the size right matters more than age alone, so here is what to check before you buy.
- Measure rider height: Rider height is the most reliable guide. This bike comes in 12, 14, 16, and 18 inch wheel sizes covering roughly 31.5 to 59.1 inches of height.
- Check the inseam: Measure your child's inseam and compare it to the saddle height so their feet can reach the ground comfortably while learning.
- Look for training wheels: Removable training wheels let a beginner build stability first, then transition to balancing on two wheels when they are ready.
- Prioritize the brakes: A hand brake sized for small hands plus a coaster brake gives kids two intuitive ways to stop, which is reassuring for new riders.
- Plan for growth: An adjustable saddle and handlebar stretch the useful life of the bike, so you are not shopping again next year.
What age and height is the 12 inch bike for?
The 12 inch size suits children about 3 to 4 years old with a rider height of 31.5 to 41.3 inches. Larger wheel sizes are available for taller and older kids.
Does it come with training wheels?
Yes. Removable training wheels are included so beginners can build confidence, then come off easily once your child is ready to balance on their own.
How much assembly is required?
The bike arrives 85% pre-assembled and includes a guide, and no extra tools are needed. Most parents finish the setup in just a few minutes.
How does the braking work?
It has a hand brake with a shorter reach for small hands and a rear coaster brake that stops the bike when your child pedals backward. A fully enclosed chain guard protects little fingers.
Does it have a kickstand?
The 12 inch bike does not include a kickstand. A kickstand is included with the 18 inch size for easy parking.
How does shipping and returns work?
This ships from our US warehouse, and orders over $100 qualify for free US shipping. We also offer 30-day returns and real human customer support if you need help.
