    Bike Review

    I don't usually take the time to write reviews, but I had a great experience with customer service. They were super helpful and very pleasant. The bike are built with quality. They go together very easy and the videos are helpful as well. Once assembled, my kids were out riding the bikes that afternoon and learned how to pedal without training wheels in about an hour.

    Brakes issue

    Unfortunately my son has not learned to ride his Guardian bike as we can’t get his brakes to work properly. I’ve noticed that’s an issue others have had as well.

    Great for my tall 5 year old

    I got this bike for my 5 year old for her 6th birthday. She us tall for her age and I was concerned with her outgrowing the bike in a year or less. The bike seems to be perfect in size with room for her to grow. It was easy to put together with the tools that were supplied. My daughter took off with ease and had adjusted better to using the brakes now. Only issue is sometimes her chain is falling off but it's been easy to put back on.

    Very Happy With Purchase

    Purchased for an eight year old girl. Took a little time, but she has mastered riding. She had a smaller bike with training wheels in the past but never felt comfortable. This bike is expensive but very sturdy and well built. Purchased a color that her younger brother can use in the future. When determining bike size, her height indicated the 24 inch. But the 20 inch is perfect. Seat height is low now so has plenty of room to grow.

    Great bike!

    My daughter was up riding without training wheels in minutes! The hand brake is also a great feature for emerging riders. Great bike, will buy another for my son next year.

    Training Wheels Compatible

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

    Compatible training wheels can be purchased here for our 14", 16", and 20" Bikes.
