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.

Ultra-lightweight Design

The Guardian AIROS is made of ultra-lightweight, aircraft-grade aluminum. It’s exceptionally durable and extremely easy to control, making it both super 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 AIROS use a matte black frame with glossy heat-transfer decals, for a popping contrast that will blow your kid’s mind.

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 top tube makes our bikes easy to get on, and a lot safer if your kid comes off their seat in a hurry.

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.

No Coaster Brake

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.

Very happy

5 yr, coasting on her prior bike (woom 2). I initially thought this bike was too big, but an hour later, she was riding a bike for the first time. The braking system works great. I did reach out to the company when I thought it was too big... they emailed immediately. Great customer service & love the bike.

Ethos 20in Small

The bike came in earlier than expected. Easy to install. My only problem was that the bike wheels were not properly inflated..Luckily I had a pump on hand. The bike was light enough for my son . My 7 year old son really enjoy Riding the bike. Him and his older brother enjoy racing each other now. To me that’s what’s really matters.

16" and 20" small Guardian bikes

Our 5 year old had been riding a 16" Liv bike for about a year but was having trouble progressing beyond the petal brakes and training wheels. We purchased the 20" small Guardian bike and removed the petals. After a few weeks of balancing we added the petals and she took off like a rocket! The handbrakes have given her such confidence when she rides. They really are a game changer. We loved it so much we bought the 14" for our 3.5 year old. She started on a cheap Walmart 12" with training wheels but tipped over because of the short wheel base. After about a month on the Guardian without petals, we put them back on and she was riding on her own, first try! The 14" Guardian was perfect while she was learning to balance but with petals it was a bit small. So, I contacted Guardian and they sent us a 16" as a replacement, free of charge, and asked that we donate the 14". Guardian's customer service is remarkable and their bikes are by far the best purchase we've made. We get compliments on how gorgeous the bikes are all the time. We are so excited Guardian helped us get both of our girls riding without training wheels in time for summer. Thank you!

High hopes for success!

We got this bike for our granddaughter, who is turning 5 in July, and had just learned to ride a bike. Unfortunately, when she tried out the Guardian bike, we hadn't adequately prepared her and she crashed. Our fault, not hers. She's currently refusing to get back on it, but we are confident her fears will be overcome and that she will be riding it this summer! We have no qualms about the bike, which still seems an excellent choice!
