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. Decision. EVER!!!
Well, maybe not “ever” but certainly up near the top. Our 7 yo son was incredibly hesitant about riding a bike, for fear of falling. He’s had a little Schwinn for over a year now & rode it maybe a handful of times with the training wheels. And even then was only a few minutes at a time. He just did not enjoy it. A friend told us their kids’ Guardian bike did the trick so we pulled the trigger & got one. I put the pedals on right away & he tried riding it but got instantly frustrated because he couldn’t balance & ride it. Then, ding!, I remembered he needs to learn to balance first, so I removed the pedals. He scooted around like that for 4-5 days, maybe 10-15mins at a time. Then, on went the pedals and off he went!!! My heart nearly exploded with pride. :’) Our first family bike ride is something I hope none of us forget. Now he rides every day after school. I honestly think the surestop break system is incredibly key here because the breaking on the Schwinn (pushing pedals back in order to break), messed with his head. Also, the design looks waaay more comfortable for him. Perhaps if he had a Strider when he was little, he may have learned to ride quicker. But because of the design of the Guardian bike, and the break system, Guardian would most likely still be in our lives. It really is a game changer. Cannot recommend enough!!
Blessings to Guardian Bikes!
My eight year old grand daughter was struggling to learn how to ride a two wheeler. I went with the recommendation of the 20inch large. I was able to assemble the bike myself. My granddaughter got on the bike and was comfortable with the quick response of the brakes. She also liked how she could lift the bike herself. We adjusted the seat height easily so the balls of her feet touched. She started on her own and was able to balance so much better! She said the bike made all the difference! She has been riding now and more confident each time. Thank you!
Extraordinary Customer service/Exceptional Quality
I bought GB for my grand daughter-7 yrs. I had purchased 3 second-hand bikes. She loves to ride but skiddish and awkward so rides together were stressful. I searched and found Guardian....WOW. Customer service is impressive. I can text, call or email and I get response even if to say we will address asap. Guardian bikes cost more than typical kids retail bikes ...BUT the manufacturing is in USA, detail has been researched and implemented specialized to childrens' needs, size and abilities. Then to seal the deal the company supports and advises you with sizing/purchase. This is the type of customer service that my parents told me existed and we so rarely see in our society that values profit above people. Its seriously exceptional. Our kids are priceless and bike accidents can happen but Guardian has created equipment and service that matches the value of our children. They ask if exchanging bike that you donate rather than return. Like who does that in 2024. I cant say enough good about Guardian. Oh and she rides with less stress. She took a hill in the neighborhood reluctantly at first but I explained how the brakes worked. I ran along side first try. She got to bottom of the hill and looked up at me smiling proud and said, "I can do this. I'm going again by myself." Thanks to Guardian for commitment to safety and for allowing my Ava to be proud of herself!!
Amazing bike!
We were on the fence for my daughter’s 7th birthday about getting this one but went for it. We trusted the sizing guide and it was perfect! It arrived quickly and was super easy to put together. We set it up as a balance bike and she practiced twice. On her third try we put the pedals on and off she went! On her old bike she was always terrified but right away with this one she had tons of confidence and pride! Thanks for a memorable birthday!
We love guardians bikes!
My 5 yro son upgraded from 16inch to 20 inch and my 3yro just sat on the 16 inch bike and rode!!
