United StatesGreat 20" single speed bicycle and easy!
Having worked in bicycle retail and service for nearly 10 years when I was younger, my expectations were tempered some with these bicycles being ordered online and delivered to your door. However, upon receiving the bicycle, and thinking that I needed to do what I had done while working in a shop, which is basically tune the entire bicycle during assembly, I didn't have to do that with this one. A little brake adjustment was really all it needed, along with a headset adjustment. Everything else was good out of the box. The bicycle looks great. The one we got was a nice neutral color. The geometry is perfect for my daughter who is just over 4 feet tall. As far as teaching my daughter to ride it, the suggestion videos were great. My daughter had a strider bicycle, but never really got the whole balance thing (may have partially been due to the bicycle being too small). Anyway, I was able to teach her how to ride the bicycle in about an hour. Absolutely amazing! The joy we got (both myself and my daughter) has built a great memory for us. Thank you Guardian Bikes. You all are definitely on to something here!

United StatesShould have done it sooner
My daughter was struggling with a bigger bicycle with training wheels. We got her the Guardian and she took off in less than 15 minutes. Two weeks later and she is able to ride miles on her Guardian bike! So happy we bought this bike, just wish we did it sooner!

United StatesBest bike!
This bike is fantastic. You can tell that a lot of time and thought were put into its design. My daughter learned to ride in just a couple of days using Guardian's suggested strategies. Wish I would have had this bike with my oldest child. Will definitely be buying another Guardian bike for my other children

United States6 Yr. Old off traning wheels in 15 minutes
My six year old was off to the races without training wheels in about 15 minutes after pulling her guardian out of the box, very happy with this purchase. Will be purchasing another for my four year old soon! Bike is great quality as well. Thanks!

United StatesGreat bike!
With the help from multiple team members, the correct bike size was chosen for our daughter, and a shipping error on my end quickly corrected. Our daughter freshly 6, 44” tall, and was at the cusp of the 16 and the small 20. Was guided to go with the small 20! She will grow into this incredibly! Very happy with the choice. Originally coming from a strider 14x, with pedals, she transitioned to this bike with grace. For the first maybe 5 minutes she was a touch wobbly and hesitant, adjusting to the new frame size. But then ride away with confidence. We are very pleased with this choice. Color way is great, and she is so impressed with the hot pink wheels on her teal bike. Thank you all!
