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.

Best bike ever
This bike is the real deal- I got it for my 8 year old grandson’s birthday. He literally rode this bike within 10 minutes of trying. And within one day navigated turns, hills and the brakes. If you are thinking about a purchase you won’t be disappointed.
Highly recommend
Bought for my son who was giving up on riding a bike without training wheels. Decided to give Guardian a chance after reading the reviews. After about 2.5 hours the rest is history and my son rode the bike for 4 miles non stop with the biggest smiles on his face. Love this product and have been telling everyone about our experience. Great product keep up the great work!
Well worth it
Very happy with the purchase of 20” bike for my grandson. He rode without pedals initially then asked that they be put on and that was it. No more fear and a happy kid
Lived up to the ads
Wonderful! My very reluctant 7 year old was riding on his own in 3 days!
Best purchase ever!
I've already told everyone I know how great this bike is. My daughter hopped on the bike and instantly rode. The joy on my daughter's gave was worth every penny
