    Great 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!

    Great bike

    Our son has never enjoyed bike riding. It’s been a struggle to get him to want to ride a bike. With this bike, he has more confidence and is more willing to ride bike. Very good and lightweight and the training wheels help give him the confidence along with training on self balancing. Happy with our purchase!

    Excellent! I bought this bike for my 7 year old grandson who has been frustrated trying to learn on his bike with training wheels. He complained that the bike was heavy, and he couldn't push the pedals and felt he was going to fall off when leaning on the training wheels. Within an hour he was able to push the pedals while my son wrapped a towel around his waist and ran with him as he pedaled and before you know it, he was riding a bike. It was so exciting to watch. A week later and he's riding all the time. Thank you.

    Great bike but missing items due to overselling

    I bought the bike as a surprise for my 6yo daughter. We brought the whole box with us camping and when I went to open it we were disappointed to find no helmet! Come to later find out that they oversold the helmet and didn't ship us one. They didn't know when they would be getting more in stock, so they issued a refund two weeks later. Bit of a damper on our trip. But once we got home my daughter had zero issues learning to ride her new bike. The bike itself worked out very well and we go on bike rides daily. Would've been 5 stars had the helmet been in the box or if they would've communicated that sooner.

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