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.
Kid Friendly Gear Shifter Learn more about
Our unique gear shifter is designed to make shifting easy with a simple twist function and a red visualizer that changes its position depending on which gear your child is in.

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 Learn more about
Our bike colors and designs were developed by kids, for kids, to make our bikes the coolest bikes on the block. Our Guardian 20 Inch Large Bike line uses water-transfer decals with a clear coat finish, giving the whole bike a polished shine.
Double-walled Rims Learn more about
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.

great bike for 6 year old
it was very easy to put together, fit and finish is superb, son is very happy with bike

Great bike!
My daughter loves her new bike! It was the perfect birthday gift. It was easy to assemble and we all loved all the color options!

Amazing bike!
Finally found a 20” gear bike that is not too tall so my boy can reach the ground. Gears works smoothly, the brake mechanism is great and love that it’s not heavy at all. It was also pretty simple/fast to put together.

High Quality Kids Bike
This is my son’s first bike with pedals. It is amazing quality and he is almost riding on his own after his first time out. We have been using the towel method to help him adjust to balancing better while he figures out the breaks, etc.

Up and riding in a weekend!
Love this bike. Assembly was straightforward and fast. My daughter needed some help Saturday, and by Sunday she was flying around all on her own on her new two wheeler. The brakes are awesome as is the gear shift. The bike feels so sturdy yet it’s light weight for her to be able to get it moving. We loved it so much we ordered a second one in 24” purple for my 9 year old two days after it arrived! Both bikes arrived within 48 hours from when we ordered too.
