The Guardian Ethos has a lightweight steel frame, making it easy to control while still durable enough to outlast your kid. Like every Guardian bike, it’s kid-tested to be safe and fun to ride.

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.

Overall very positive experience. Assembled the bikes last night. Assembly was very easy. First use was today. One bike was flawless, the other had an issue with chain coming off in shifts to first. Adjusted the “L” screw and I think things are now ok.
It’s a good bike design. I saw the same exact bike by Cannondale, with the only difference being the Guardian has 1 brake lever instead of the traditional 2, and the Cannondale has the quick disconnect for the wheels. The Guardian is priced cheaper, so I’m happy to have purchased this one. The only possible negative I’ve noticed is the chain doesn’t slide back into the selected gear easily when downshifting, but otherwise it’s a great bike and my 6 year old girl loves it.
My son LOVES his bike - it took less than a minute (no joke) for him to master and be a 2-wheeled rider!! When the bike came (it was an early birthday present), there was no seat included, and no protective wrapping/packaging on the bike - I was told the seat would come the next day but we waited 2 days. Not a huge deal, just a little bit of a letdown for my son, who was so excited to ride his new present! WE LOVE the bike though, and will definitely use Guardian for new bikes as he grows.....like so many other reviewers said, I also cannot get my son to come inside. He wants to ride All. The. Time. which is fine by mom! :) Thank you, Guardian Bikes!
Can't Rate it Perfect but
Really it was 4.5 stars, because the bike came without the seat. Customer Service was spot on, very easily accessible to handle the problem and answer questions, and the bike is great quality/easy to assemble. My son loves it.
Very happy with bike. It would have been a 5 start review if the shipping had not been delayed.
