Purchased the bike for my son's 5th birthday. He is tall for his age but the low standover height makes it manageable for him.
Shipping was quick, bike packaged well, and not many adjustments at set up. Also, the fact that they ship direct is a plus in and of itself as many manufacturers will only ship to a bike shop. And if you live in Texas the number of LBS's that carry legit kids bikes are very few and far between.
Shifting is smooth and after only a couple of rides, my son has started to figure out how to shift. Now that he can climb, it has become is favorite thing to do which makes me proud, a little perturbed and very winded. Ha!
The brakes are definitely an improvement from cable v-brakes. There was enough adjustment in the levers to allow for 1-finger braking by small hands and he's taking to the technique after slapping the binders on a couple of times when grabbing a handful of brakes.
All around a great bike that we will get a lot of use out of. Our family rides a lot and if you are looking for a quality bike that will allow your child to progress their skills and confidence on the bike when moving up to 20" look no further.
