SureStop, Easy Reach Brakes
Learn more about
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.
No Coaster Brake
Learn more about
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.
Kid-specific Geometry
Learn more about
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
Learn more about
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.
Adjustable Seat
Learn more about
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.
Eye Candy Decals

What an amazing little bike!
Wow...so impressed with the delivery and assembling of this bike. So excited to give this to my daughter in a couple weeks. This will be her first bike. So amazing.

Best bike on the market
Guardian bikes ordering and shipping process was flawless. As soon as the bike arrived the minor installation was super easy. Within a few days of my daughter who is 6 fave her the confidence to ride a bike without training wheels.

Love it!
My daughter loves her bike!

Amazing!
After 2 years of trying to get my 8 year old to ride his bike, he rode this bike in 24 hrs or less! Unbelievable. He is now cruising all around!!

A solid choice.
My daughter is a tall kid. Bikes that fit have been too tall for her comfort. We started her off with a strider style balance bike. She mastered that but quickly became too tall for it. She inherited a training wheeled bike from a cousin but was too tall. She was jammed up on it and couldn't smoothly pedal. I ordered the guardian and she loves it. We started without pedals for a couple sessions. Saturday we installed the pedals and within minutes she made her first solo run. There's work to be done but we're well on our way. The guardian is designed to actually fit the kid without the awkward lack of leg room associated with most kids bikes.
