So much to love in one bike

SureStop, Easy Reach Brakes

With SureStop, there’s only one brake lever, so your kid can’t get confused when things happen fast. Our patented brakes won’t ever flip the bike, and the lever is in just the right place for kid-size hands.

Ultra-lightweight Design

The Guardian AIROS is made of ultra-lightweight, aircraft-grade aluminum. It’s exceptionally durable and extremely easy to control, making it both super safe and fun to ride.

Eye Candy Decals

Our bike colors and designs were developed by kids, for kids, to make our bikes the coolest bikes on the block. Our Guardian AIROS use a matte black frame with glossy heat-transfer decals, for a popping contrast that will blow your kid’s mind.

Kid-specific Geometry

Kids don’t just need smaller bikes. They need different bikes. With all the right proportions. They need smaller grips. They need less distance between the pedals. They need shorter crank arms and a low center of gravity. All Guardian bikes are designed for kids, from the ground up.

Low Step-over Height

The low top tube makes our bikes easy to get on, and a lot safer if your kid comes off their seat in a hurry.

Adjustable Seat

Every Guardian bike seat is both easily adjustable and easy to lock down. You can adjust the height to fit your kid as they grow up with the bike.

No Coaster Brake

Guardian bikes never have coaster brakes. Period. New riders backpedal to keep their balance. If a bike has coaster brakes, this stops the bike, just when they were getting the hang of it. Our brakes stop faster, with much more control.

Our bike colors and designs were developed by kids, for kids, to make our bikes the coolest bikes on the block. Our Guardian ETHOS line uses water-transfer decals with a clear coat finish, giving the whole bike a polished shine.

Awesome company

5 stars. Bikes shipped quickly, were easy to unbox and assemble. Ordered the wrong size (my fault) and a replacement is already on the way. Kids love the bikes too! Happy I went with guardian.

She just learned how to ride bicycle in less than 10 minutes

My 7-yo daughter never used balance bike and she did not take any cycling lessons. She likes to be among her neighborhood friends who can cycling and she chose the color of Aqua Pink. The next day we get the bike, her dad spent a few minutes with her, and then we all got to see her cycling video. Just that easy!! I could still remember the whole afternoon my parents held my bicycle and ran loops and loops to let go and I fell terrible once I found out on the day I learned to cycle. My husband and I later found out we even forgot to pump the bicycle.... We were just that prompt and did not expect she could learn. Now she is cycling almost every day after dinner with her neighborhood friends. In addition, we received a few tools in the package and we lost them all on the trash day when we throw out the box .... I believe these are all general tools and we might be able to find replacement. But I tried to contact Guardian customer service. They responded in a short while and promised to send me some replacements. It was so nice experience. The price is not cheap and we got the best design, product and service! DEAL!!

Best Bike and World Class Customer Service

My daughter who is five years old took off on her bike after 5 minutes of balancing. She loves her bike so much she refuses to ride in a car to go to nearby places. Their customer service is exceptional. All is all I am so grateful for our experience with guardian. And we will definitely be back to get a bigger bike when she outgrows the one she already have.

In almost an instant

Our twin girls we're struggling with big box store bicycles but that all changed once they received the guardian bikes. Literally, within 10 minutes, they were riding around the cul-de-sac like they've been riding for years. Purchase was easy, shipping was extremely fast, and a quality product.
