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.

Broken :/
The process of putting together the bike was great with the videos until I went to attach the handlebars. I unscrewed the bolt to be able to insert the handlebars and now it will not tighten. Not sure if something is broken but this has significantly delayed us using the bike. I have sat there trying to figure this out for way too long and now the bike is sitting waiting to be put together in the garage.
20” large bike
Easy to put together! Made very well! Beautiful bike! Grandson loves it! Chain has come off several times as he rides. Is there something I should adjust?
Good Bike a little too big
Quality of the bike is great. I ordered online and followed the instructions for both height, leg height, and age. Recommended bike arrived a bit too large. Decided to keep the bike as my kid will grow into it likely in the next 6-12 months, and I didn’t want to go through the hassle of returning it. I bought a second bike for my kid in the mean time, different brand, that we tried out in person at a store. This second bike will get passed down, so not a big deal in my situation. Quality of bike I’d rate 5 stars, deducted a star because fit was too large following online ordering instructions. Obviously, getting the right fit would not be a problem if you first get fit for a bike in a store before ordering. I didn’t do this, because I wanted it to be a surprise. Oh well…
New bike
Outside of the fact that the front tire inner tube was defective, would not hold air, and needed to be replaced, we are very pleased with the bike.
Gift for Grandson
Overall an excellent experience involving the purchase, the shipping, the assembly instructions, and the product quality. The only problem was that the handle shifter was too hard to upshift for my grandson.
