Why Kids LOVE Guardian Bikes
Award Winning SureStop Brake System
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.

Return Made
Either the pedals or the crank didn’t pass QA/QC checks as both threads for the pedals stripped the crank. Got a useless bike on my kid’s birthday.

Hi Jack, We are so sorry about the issue with your first bike. We hope they are enjoying their new Guardian!
Can’t use out of the box…
For the price of this bike, I should be able to assemble it and my child ride. The brakes are so tight that neither wheel can spin freely. That would be alright if there was an actual instruction manual not 1-5 minute videos to watch on assembly. Spent an hour trying to google what to do to loosen the brakes and wasn’t successful. Now here I am taking a brand new bike to a repair shop in order to even be able to use it at all.
Order I completed, can’t provide a positive review
They still haven’t delivered all parts of the order, and other orders …. Months

Hi Jose, Thank you for pre-ordering. It looks like everything has been delivered. We hope you are enjoying your bikes. Please reach out if you have any questions. We are here for you. :)
Have been having issues with the tires of this Bike like forever. Would not buy this again or recommend to anyone
Since the day we bought this, we had to keep pumping air into the tires forever and after few days, we just gave up and put it aside. For the cost we payed, we are extremely disappointed.

Hi Ravi, Adam here at Guardian bikes. Sorry to hear you are having issues with the tires. There is a tube inside of the tires that holds the air and likely that has a small hole in it. Our bikes come with a 1 year warranty for these instances and we can help you get the tube replaced. Please let me know if you want to move forward with this and sorry for the trouble! Thanks, Adam
