Why Kids LOVE Guardian Bikes
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.
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.

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.
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.

Perfect bike for my 7 yr old Grandson
This bike made learning to ride for the first time a very easy experience.Had a small glitch with the chain but followed the video and resolved it.My grandson was determined to do it in one day and it happened! Thank you
Amazing bike
Our son picked up on riding his new bike within a day. We had practiced with other bikes and he struggled with pedaling and turning. After a few practices with us by his side, he took off on his own. Worth the price!
Worth the price
Great quality, my child will grow with it, and easy to learn how to ride.
Speed demon
My son loves his new bike. Couldn't get any easier to set up on delivery, only problem he has is the shifting is a little tight and hopefully it'll loosen up. He also is not used to it so maybe it'll get easier when he gets the hang of it. But all in all I'm very happy with the purchase and so is he. He's also still waiting for his 100 mile certificate, asks me multiple times a week when is it going to come so hopefully that arrives soon! He rode hard for it
Greatest Bike ever.
I was able to teach my son in 15 minutes. He was so afraid of falling, but this bike gave him the confidence he needed to ride on his own. Definitely recommend.
