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.
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.
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.

Christmas gift
First class experience. My daughter wanted this specific type of bike for her daughter. I ordered it and it was delivered to my house in 2 days in good shape. The instructions for assembly were very clear and the bike was mostly put together anyway. I hope my granddaughter likes her new bike!
Changed My Kids Confidence
My daughter is 9 and has not been able to ride a bike. We had tried everything. In 1 day she was riding with ease. Week two she is riding 10 miles a day. It has completely changed her self confidence and she asks to go out first thing every morning. Thank you for making this bike.
Great bike and easy to assemble
It was just 5 min to place the handle bar , rest was pre-assembled and my son started enjoying the pedal-less balance bike for now. I f I knew how to remove the pedal bar that came pre-attached it would have been awesome, but he is managing balancing aspect even with the pedal attachment bar.
I haven’t opened the bike yet, and I know I love it
I received my daughter’s bike a couple days ago, but won’t be opening until Christmas. I will say just customer service and shipping alone gets 5 stars. I was trying to place my order and use the code for the bike lock and pump but it wouldn’t work. I just ordered the bike without, I then received a different code but the code only works when purchasing the bike. I sent a question asking if there was anyway to add it. Within a minute of sending the request I received a confirmation email for the lock & pump. Within hours I received emails saying my items had shipped. Most companies would have said no to my request because it should have been done at point of sale, I wasn’t even going to ask because of this. And shipping within hours blew me away. I know I will receive plenty of help if needed trying to teach my daughter to ride a bike or if any problems arise. I look forward to Dec 25th when we get to unbox her.
Fantastic Bike
After struggling with trying to teach my 7 year old grandson how to ride a bike using training wheels to no avail, I found Guardian Bikes online and remembered them from a Shark Tank episode. After watching the videos on the site and measuring my grandson, I decided to take the plunge and purchase a bike. 48 hours after receiving his bike, my timid, nervous grandson is now a proud, confident bike rider. Thank you Guardian! This was a great purchase and worth every cent.
