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.

Learned in 30 min's
Grand daughter 6 years old LOVES her PINK 20 in gaurdian bike!! She was very frustrated trying to ride a bike! She coukdnt coast on coaster bikes cause the peddles move... to bike for a strider bike. This was the answer, didn't out on the peddles, she could balance! She said grandma count to 15 like in your video! I said yeap, she said put on my peddles. Put them on and she took off riding!! The smile on her face couldn't get any bigger!! Brakes are awesome, she could reach it and they WORK!!! She will be learning the gears next. But it's a bike she can grow with for a couple if years!! Thanks Gaurdian for the BEST bike out there!!
4th Guardian bike!
I purchased two 20” large bikes for my 6 1/2 year-old granddaughters to replace their 16” guardians. I was apprehensive because I didn’t think they’d be able to shift gears at their age, but I went ahead and ordered them and they hopped on & took off with zero issues. Great quality, fast shipping, great customer service - can’t say enough good things!
The perfect bike
My son started on a balance bike when he was younger and excelled at it. I thought the transition to a “big kid” bike would be easy, but it was ANYTHING but. We tried training wheels but it seemed to make things worse as he started to rely on them too much. Enter the Guardian bike. We let him get comfortable on the bike for about a week before putting on the pedals. Now he’s a pro! Highly recommend, especially for nervous/cautious kids.
But be like me and wait to buy!
I was having a little struggle getting my five year old riding. She never liked her balance bike and wasn’t fond of her store bought bike with training wheels. We tried for a few days without training wheels with no luck. I kept debating on ordering a guardian bike for way too long. The bike came fast and we waited a few days for warmer weather to test out. I don’t review things. However, I was so impressed with the results I must. We took the pedals off for a little and before I knew it she was balancing. We put the pedals back on and no joking, she was riding the bike on her own within 30 minutes. She has become a bike enthusiast and wants to have her friends over to teach them how to ride. We have recommended these bikes to all our friends and people who stop us on the bike path. Seriously, don’t wait..you won’t regret it.
