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 line uses water-transfer decals with a clear coat finish, giving the whole bike a polished shine.

Ultra-rigid Construction

Our Guardian AIROS are built with a threadless headset for a much more secure assembly, especially over the long term. The bottom line? That headset—and the handlebars attached to it—won’t ever start to wiggle on your kid.

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 cross bar makes our bikes easy to get on, and a lot safer if your kid comes off their seat in a hurry.

Premium 7-speed Shifting

Our easy twist shifters are simple and intuitive. Shift one way for higher gears, and the other way for lower. Easy, with plenty of range for even the toughest hills.

Double-walled Rims

Our double-walled rims can stand up to the extreme beating of a kids’ bike without bends, dents, or buckles. Even under the weight of a grown man. We tested it. A bunch of times.

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.

Smooth Welding

Toughness is built into every Guardian AIROS, but we smooth the roughness out—of the seams, that is. Our AIROS frame welds are reinforced for extra strength, then polished to perfection, without a single abrasive edge to mar that stunning paint job.

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.

Lightweight Design

The Guardian Ethos has a lightweight steel frame, making it easy to control while still durable enough to outlast your kid. Like every Guardian bike, it’s kid-tested to be safe and fun to ride.

Low Step-over Height

Standard Shifting

Our grip-shift components are simple and intuitive. Shift one way for higher gears, and the other way for lower. Easy, with plenty of range for even the toughest hills.

Double-walled Rims

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.

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.

Excellent Bike!

My grandson was so happy when we presented him with the 24' Ethos Bike for Christmas. We weren't sure it would be delivered in time as I ordered so close to Christmas. The customer service with Guardian Kids Bikes is unbeatable. They delivered it in time for Christmas. My grandson who just turned 9 said he had done some research and was hoping he would get this brand! It is everything they advertise it to be.
