20 Inch Large Original Bike

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 Original 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 Originals use a matte black frame with glossy heat-transfer decals, for a popping contrast that will blow your kid’s mind.

Ultra-rigid Construction

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

Shimano Shifting

Our Shimano 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

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

Amazing bike & service!

We are so happy to have a safe new bike for our daughter. Trust the ride-sizer on the website. I thought there was no way our petite 6 year old could fit on a 20 inch bike, but she does. And it’s perfect! We will only buy Guardian bikes for our kiddos from now on!

Awesome bike

Purchased a boy’s 20” Guardian small bike for my grandson. He thought it was awesome. He loved the red and black colors, the brakes, the kickstand and especially the smooth fast ride. But most of all, his dad loved that it Only took five minutes or less for him to assemble. Awesome bike that appears safe too!
