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.

Great bike and great customer service

I came across Guardian Bikes when I was researching bikes for my 7 year old grandson. I found cheaper bikes, but no other bike that was developed with kid safety in mind and that had consistently excellent reviews. The bike was a Christmas gift and it only took dad and granddad a short time to get the bike ready to ride. My grandson rode was very excited and started riding it immediately. The only problem we have had was that my grandson hadn't ridden a bike with gears before and jammed the gears when he tried changing them when the bike was stopped. We contacted customer service and they couldn't have been nicer. They immediately sent us the upgraded shifting mechanism which is easier to shift and told us to send them the bill for having a bike shop install it. Wow! I highly recommend the Ethos 20"large bike! An oh yes, my grandson loves it too!!

Easy process, great results!

I loved the ride finder tool. I was a bit skeptical about buying a 20" bike for my 4 year old, but it fits him perfectly. Set up and building the bike was so simple and the videos were great. Best of all, my son was able to skip training wheels and was riding his first pedal bike within 15 minutes of first trying it out.

16 inch Ethos

Our son, who is on the petite side for his age (5 going on 6), needed an upgrade from a 12 inch to a 16. We wanted a light-weight, smartly designed, well-priced, and high quality bike. After a lot of research, we went with the Ethos and are thrilled with this bike. Our son has a blast when he’s riding, and we love the safety features! Shipping and install was a breeze. Highly recommend!
