20 Inch Large Ethos Bike

So much to love in one bike

SureStop, Easy Reach Brakes

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.

Lightweight Design

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.

Eye Candy Decals

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.

Kid-specific Geometry

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.

Low Step-over Height

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.

Standard Shifting

Our grip-shift components are simple and intuitive. Shift one way for higher gears, and the other way for lower. Easy, with plenty of range for even the toughest hills.

Double-walled Rims

Our double-walled rims can stand up to the extreme beating of a kids’ bike without bends, dents, or buckles. Even under the weight of a grown man. We tested it. A bunch of times.

Adjustable Seat

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.

2nd guardian bike I have ordered.

My grandkids love the Guardian bikes. Now I need to order another one for the next child’s birthday…I hope they have more colors so they can tell their bikes apart!

First Pedal Bike

Overall very happy with this purchase. The front tire did arrive with a puncture in the inner tube, but they shipped me a new one overnight so I would have it in time for my sons birthday. Thank you Guardian Bikes!

Excellent bike - Stellar Support Service

The bike is excellent and the brake system is second to none. My child is more confident handling this bike than any other tried - and so am I. No adjustment time needed, very safe. That is a huge plus as we can go together biking for more miles and time! But, that's not all. Upon receipt of the bike order, I realized my child would outgrow the bike in no time, and had to return it to pick the next size. Support was extremely responsive and offered to DONATE the bike to the charity of our choice instead of returning it! How great is that? We received the new bigger bike in 2 days! Incredible bike and incredible support! I am recommending Guardian Bikes with absolutely no reserve.
