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.

Bike isn’t functional The breaks are interfering with the wheels
Hi Christina, Oh no! I'm so sorry to hear of the issue with the brakes! We can definitely help with a fix. First, would you mind sending over a photo of the front of the bike? -Laura @Guardian Bikes
Delivery disaster & missing bolt
The experience was really poor. The delivery driver backed into our fence and broke several parts. They drove away but my neighbors witnessed it. The other issue was a missing bolt on the bike tire. We had to go to 3 different hardware stores / bike shops to try and find one that was the same so we didn't have to order it all over again and wait

Hi Neil, We're so sorry for the trouble! My teammate Adam followed up with you via email, and we'll definitely get this fixed. Thanks, Kaitlin @ Guardian
Late and Grips
The delivery was late and the hand grips on the gear switch handle slide off.
Horrible service. Bought the bike for a birthday present and waited months to receive my order. Each company email update was nothing more than a strategic delay excuse.
