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.

Shiva: Difficult to setup brakes
The assembly process was a bit tedious since the front brake setup was complicated. Unfortunately, I am still not able to setup the front brakes in a safe manner.

Hi Shiva! Oh no, I'm so sorry to hear that the setup didn't go smoothly! I would love to help with this and make sure your new bike is setup in tip-top shape. Would you please email us a few photos of the front of your new bike so we can take a look and give you some assistance? -Laura @Guardian Bikes
Good, except for front brake
The bike was easy to put together, but the left side of the front brake is staying against the tire causing friction. I don’t know what to do about this. I’ve had this issue with other bikes in the past, that’s why I chose this bike. I didn’t think I’d have this issue.

Trouble with Breaks
My son loves the bike but I had a great deal of trouble putting the breaks together. I called guardian and received virtual help but I'm not sure if I fastened the breaks properly. I shuffled a great deal of break wires from the back wheel in order to correct the breaks and it ended up looking pretty sloppy. The bike is expensive and the breaks are the biggest reason I buy guardians but I think having to put the breaks together myself is not dependable and I have no real way to know if I did it correctly. The company gave me a $50 refund for the hassle but I live in NYC and if my 8 year old is unable to stop in the city due to breaks that would be terrible.

Enjoying bike. Problem with gear shifter
My son has really enjoyed the bike. This week we started having issues with the shifter in the back wheel. When he would try to go to the largest spoke, the chain would pop off. When he shifted to a smaller spoke, the chain would get back on and work properly. Now, since yesterday, the pedals will not even rotate. I am frustrated since I know nothing about fixing bikes. I am going to have to take it somewhere to be fixed. Otherwise, we like the bike.

Hi Sarah, We have over 20 years experience between us working on bikes. Please send us some photos to [email protected]. We can help out. :)
Front brakes not working
The bike arrived 20 days after it was ordered. Seems like a king time to get a bike delivered. The front brakes did not work, the instructional video did not help, the "noodle" was installed by Guardian incorrectly. I had to take it to a bike shop and leave it there for a couple of days. I hope they can put the brake together correctly, because whoever tried to do that at Guardian bikes did it incorrectly.
