Light-weight and well balanced*
Overall happy with the bike. Frame seems solid, very light weight. Easy to assemble. Love the built-in spring loaded kickstand. Appreciate the quick release crank design for converting from a balance to pedal mode. Would recommend!

la compré para mi hijo de 4 años, ya va dejando su bici de equilibrio y por la costumbre la usa actualmente sin los pedales, lo cual es genial, crece un poco más y le pondré los pedales

It’s a gift for me as much for my son!
Why did you pick this product vs others?: See below: Weight: So light, my 5yo loves this bike and it rides like a dream, he is so much more self reliant, and able to pedal up hill on his own. Ease of assembly: The pedals are amazing quick disconnect, all you have to assemble is slide the seat in place, pivot the front wheel, and snap on the pedals. So easy! Ease of riding: My son is so much more confident riding this bike, and I really appreciate it having both a front and rear brake, with a freewheel cassette on the rear wheel. Looks: In a word: amazing. I wish I could get one of these I. A 700c size for me to ride! My son literally goes into the garage EVER CHANCE HE GETS, to just sit on the bike. He is obsessed, and is so much more interested in riding all over the cul-de-sac and along our walking trail.

Truly Lightweight
My 4 year oldMy son outgrew his 14 inch bike and we were looking for a 16 inch bike and this is what caught our attention. Easy to assemble and the seat height is adjustable. Goood bike. We will update this after we take it on non paved roads and see how this performs.

Bad ergonomics for kids.
Handlebars are way too low for the bike size. The rider is hunched over.

great ride,rear wheel designs needs to improve the training wheel accommodations.
Excellent bike, light weight, smooth rides, works great as both a balance bike and bicycle. Comes 90% assembled. One thing I don't like about the bike is the rear wheel screws and housing not designed for training wheels. I bought the training wheel from this same vendor and the training wheel cannot be positioned steadily because of the washer and screw just cannot be tighten enough to prevent slipping, and the Allen screws are starting to deform due to the pressures and frequent I had to tighten those training wheels. Plus the rear wheel stand is also very hard to remove. When i installed the training wheels I'd tried to remove the kick stand screws but those screws (cross) also start to deform! So now the kick stand assembly is still right there, which makes tightening the left side training wheels even harder. The vendor should consider who the users are in their design, it's to be used to by young kids that most likely needs those training wheels. I would give the bike quality and ride a 5 star, but the training wheel accommodations just frustrates me too much.
