    Great bike

    Great bike, only took a couple of hours learning balance without the pedals before we put them on and she was off. She had resisted riding a bike for the last few years, now she loves it!

    Love it!

    We purchased the 20” large for our 5, almost 6 year old, who was already very comfortable on a 16” woom 3. The transition to this bike was seamless. The ride is smooth and he loves going for miles long rides around the neighborhood. He picked up the gears right away. It’s a pretty intuitive system. My only qualm was upon unpacking there was some type of adhesive where it looked like a sticker may have been removed. I still have been unable to get all of it off. But overall, the value for the price cannot be beat!

    It really works!

    We've been trying to get our 7 year old to ride a bike for years. He was successful on a balance bike but when we bought a brand name bike off of facebook marketplace he could hardly pedal it, even with training wheels. It was causing him a lot of frustration. After debating it for a good 6 months, we decided it was an investment that could be returned so we went ahead an ordered him a guardian bike. He spent 1hour on day one as a balance bike, and 30 minutes on day 2 as a balance bike.... then begged for the pedals. We attached them and he has been on the bike non-stop since. It was quick to ship and very easy to assemble. I would highly recommend this to everyone! Thank you!

    Wonderful product

    We love Guardian bikes. My 6 year old mastered the 20" small super quick and noticed he was really needed to be on a geared bike. He LOVES LOVES LOVES the bike. I highly recommend Guardian bikes. My son struggled to learn to ride on another bike. After few 30 minute sessions with Guardian, he made more progress than over a year trying on the other bike. Now he asks to ride as much as we can. Also, there is an amazing "return" policy. I am very pleased with this product and company.

    Kiddo loves it, easy assembly

    Aside from me forgetting my left and my right...great assembly process, videos and online instructions were solid. Kiddo loves the bike and I am confident it'll last to the next two...shifting is a learning curve, but the braking system is awesome and should probably be on every bike out there that's not considered a "performance" model.
