Good bike and good value

The delivery was fast, assembly easy with very detailed instructions. My 5yo loves the bike. The bike seems to have good dynamics and is comfortable. There were a couple extras missing in my delivery and were very promptly replaced. Good customer service.

Excellent Bike!

My son turned 6 recently and has only ever ridden a strider bike. I got this bike because of Shark Tank and purposely left the training wheels off to not intimidate my son. The bike was already way larger than the strider bike, so I was nervous for him. But he hopped on and took off and has had no problems! I don 't know what kind of magic this bike has, but it's amazing! My son loves it and feels very comfortable with it. I showed the video regarding the brakes to my husband, and he was very impressed too - he always tells people about the brakes now! It's a really well-made bike and very safe. I am so glad we went with them. The customer service is amazing as well - The bell we ordered with the bike came broken and I emailed on a Sunday and they replied right away and mailed one out the next day! Just outstanding! I will be getting one for my other son when the time comes!

Great bike! Instant success!

This bike pedals easier than my 5 year olds last bike which was a good quality bike by REI. The biggest plus besides this is the handbrake. It activates the back break first and then the front break, which is genius. I am thankful we found this bike!

Great but breaks always seem broken

Bought the bike and things were going well. But after 1 week the front brake is constantly broken. It disconnects from the cheap metal bracket and falls off and is dangling around. Not what I’d expect from 300 plus dollar kids bike. Right out of the box it didn’t stop the front wheel from spinning and it just won’t stay on. It constantly - anytime it’s ridden - falls off the bracket. Anyone want to reach out to me to provide help is appreciated. Couldn’t find a FAQ or troubleshooting section as it all seems geared towards making more sales vs helping existing customers.

Excellent Bike

The bike is very well made and perfect for my two year old grandson. Not only is it well made, it looks great too. Excellent customer service. I highly recommend Guardian. They are a great company.
