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.
Guardian bikes never have coaster brakes. Period. New riders backpedal to keep their balance. If a bike has coaster brakes, this stops the bike, just when they were getting the hang of it. Our brakes stop faster, with much more control.
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.

Well Built, with Easy Assembly
These bikes are great and the assembly was very intuitive and easy, especially compared to another kids' bike we bought at a retail store. Sturdy, well made, and all-around excellent.
Love at First Ride
We bought two 16" bikes for our 4 year olds. The bikes were very easy to put together. The boys practiced without pedals for about an hour to find their balance (They were previously on balance bikes from 2 yrs to 4 yrs old). They both took off so quickly once we put the pedals back on. Our guys can load their bikes into the van themselves. They are not nearly has heavy as other bikes found at Target or Wal-Mart. We get compliments on them all the time. I have nothing but good things to say about Guardian Bikes and recommend them to everyone who asks. I'm so impressed with the quality of these bikes!
Guardian Delivers On All
Delivery on time, well packed, no damage, easy to complete assembly of the bike. The brakes were all set up and adjusted, and granddaughter really likes the hand brake versus backpedal, and found it easier to use, and so much smoother and quieter than her bike she outgrew. Best of all it looks great, paint job high quality finish and nice colors/ patterns, all good, zero issues to have any concerns about.
Simply brilliant product, congrats to the engineering team!!!
Our son loves his bike
Excellent customer service. We had several questions prior to ordering a bike for our son. He was between sizes so we went with the larger one. He has had a great time learning to ride and although he hasn’t mastered it yet he’s almost there. Would definitely do business with Guardian again (and I’m sure we will in the short future). Thank you
