Why Kids LOVE Guardian Bikes
Award Winning SureStop Brake System
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.
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.
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.
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.
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.

Amazing Bike and Customer Service
Well, first off, my 4 year old granddaughter jumped on her bike and took off...just like that...singing "look at me..there is no one like me...I am happy..." More importantly, the reason she was able to do that was because of your customer service. When the first bike was delivered, someone stole it off the porch! I called customer service the next day to explain our situation and without asking, a new one was put in the mail that day. Oh my! there are some good companies and people out there and you are one of them! Thank you so much for restoring some faith in humanity and ....... for making a great product! Denise Tompkins
Grandson loves it
The short videos on how to put it together was fantastic.
Decent bike, and terrific customer service
I’m a longtime cyclist and a decent bike mechanic, and I’ve been critical of kids' bikes for years. The drive to the lowest price has put kids on the road in thousands of shoddy, unreliable, unsafe rides. I bought two 16-inch Guardians for my grandchildren in an attempt to avoid that, and so far I’m impressed. Assembly, the first hurdle, is a snap. Absolutely anyone who can hold a tool could do it. The instructions are clear, everything fit, everything matched, and the tools were provided. The two bikes were ready to ride in minutes, and the extra seat posts—one short, one longer for when the kids grow—were a welcome bonus. Quibbles? None to speak of. Children's bikes always seem heavy to me, and these do, but that's hard to avoid. Components for a tiny bike aren’t much lighter than those for my large adult bikes. The extra couple of feet of tubing in my frame probably don’t add much. And while I’m not sure Guardian's "Surestop" brake system really makes the bike safer (I’ve gone over the handlebars just once I 50+ years), it works fine and can’t hurt. Rs
Overall great bike
It is a great bike! Came with an air pump to attach but no where to attach it which was weird. Overall a great quality! Would purchase again!
So happy with the purchase
We got this bike for my daughter after measuring her leg length and doing the find my size quiz and it fits perfect! She had been riding a small balance bike and took off immediately on this one adjusting to the pedals and hand brake perfectly. I was going to wait to get my toddler a bike but now he wants one from here too!
