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.

My autistic son couldn't be happier! He learned how to ride this bike in less than a day. Very lightweight, good proportions, and the braking system is unmatched. Can't wait for the adult sized bikes to come oit so I can purchase one for my oldest son. I would recommend this product to anyone struggling to learn how to ride a bike.
Guardian makes great high quality bicycles. This is my second bike from them and both kids love their bikes.
Amazing Company and Outstanding Customer Service!!
Guardian is an excellent company with an outstanding product. They stand behind their product and their customer service before, during and after purchase was so easy and pleasant to work with!! Great overall experience!
Great bike, greater company!
My 6-year-old loves riding his bike, and after getting an inexpensive two-wheeler with terrible brakes and a tire that popped, I decided to splurge on a higher quality bike for his birthday. I saw recommendations for Guardian Bikes, and I don’t regret my decision to pay a bit more for their level of quality and customer service! When the bike arrived, it was easy to put together (with extremely user-friendly online video instructions) and it just looks like a very high-quality bike. My son was thrilled, learned to use the one-handed brake quickly, and loved his new bike bell, but I was worried it looked a bit too small for his long legs. I contacted customer service, and they sent me an invoice for the price difference for the larger size bike and immediately arranged for an easy exchange. Rather than asking for me to send the smaller bike back, they told me to find a child in my community in need and donate it to them instead. What an incredibly kind and generous way to handle a tricky return! The new larger bike arrived within days of sending them confirmation that the original bike was donated, and I am still in awe of this company. If you’re wondering if it’s worth spending a little more on a kid’s bike, the customer service, safety, and quality of Guardian is worth it!
Just purchased a second one!
We’ve been so thrilled with our first Guardian bike that I just purchased the next size up for my youngest daughter. I have three daughters so I’ve purchased many bikes over the years. I always do a lot of research because safety and quality are important. This has been the best bike by far! Love the customer service too. It’s easy to put together (not much to do) and they are quick to help with any sizing questions.
