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 ETHOS line uses water-transfer decals with a clear coat finish, giving the whole bike a polished shine.

Best Bike Ever!
My Grandson was thrilled with his new bicycle! I was thrilled because the quality is outstanding, customer service Guardian Bikes provides is amazing and the products are made in the USA! Win, Win, Win! Just getting ready to order another bike for my other grandson!!!! Thank you, Guardian. Bikes you are very much appreciated.
Great Bike.
The shipping was very quick, the sizing guide was spot on! My daughter went from training wheels to pedaling in about two nights after school. She is so proud of her self and full of confidence riding. Couldn't be happier with the product.
Very good buy
My daughter loves this bike. It's light weight and very comfortable and safe. She is able to learn how to balance in 1 day and was able to pedal the next day. Great service and fast delivery. Couldn't ask for more.
Grandson's bike
He loves it. This is his second bike from Guardian
Super Nice Bike!
This bike was a gift for our Grandson George, it was a tiny bit big as we did choose the "big" model, but George got on his new bike and rode like a well experienced rider, he had just learned to ride a pedal bike. He had a big smile on his face as he rode his new bike, and he loved the colour. OMG, and the service was outstanding, his new bike was delivered in 2 days from ordering. Thanks for making beautiful, safe children's bikes!
