    Speed demon

    My son loves his new bike. Couldn't get any easier to set up on delivery, only problem he has is the shifting is a little tight and hopefully it'll loosen up. He also is not used to it so maybe it'll get easier when he gets the hang of it. But all in all I'm very happy with the purchase and so is he. He's also still waiting for his 100 mile certificate, asks me multiple times a week when is it going to come so hopefully that arrives soon! He rode hard for it

    Greatest Bike ever.

    I was able to teach my son in 15 minutes. He was so afraid of falling, but this bike gave him the confidence he needed to ride on his own. Definitely recommend.

    Love this bike!

    My girl loves this bike! She is quickly learning how to ride and feels very secure with the training wheels. we loved that it comes assembled and all we had to do was install the pedals and mount the handlebars. Instructions online were great, and it was very simple and quick. We will be ordering another Guardian bike when she outgrows this one!

    Ava’s new Guardian 20 inch large bike.

    This is my 2nd. bike that I purchased from Guardian and it was a great experience like the first time. My granddaughter just loves her new bike. She had a hand me down bike before. Her new bike fits her nicely and is easy to ride. The one lever braking system makes it so much easier for the young riders to understand how to brake. We use squeeze the lever nice and easy when riding. The little picture of the bike on the gear shifting is a nice tool to teach a young rider how and when to shift gears. So Guardian folks keep making and improving your bikes.

    Great Bike for Learning without training wheels

    Although it cost more than those you get from a big box store, this bike has been a great investment. I used the Guardian fit guide and it was accurate. This is my 6 year old's second bike and the first without training wheels. She seems to be getting the hang of it thanks to it being light weight and the brakes and gears being intuitive. I'd highly recommend this bike for any kid learning how to ride. Seems like the size will last her a few years too!

    Training Wheels Compatible

    We recommend using the balance bike method when teaching your child to ride a bike, but understand all children learn differently.
