My 4 year old is above average height for his age and is ready to transition from his kick bike. The bike would be an excellent fit except he can barely tiptoe with the seat post dropped to the clamp. A kid learning to pedal should be able to flat foot to be confident and comfortable. This seems like it would be an easy fix for specialized as there is an extra 2” above the weld on the seat tube and at full extension the seat height is ridiculously high. Otherwise excellent bike quality for a super price, I would have given 5 stars if my kid wasn’t discouraged from the stand over. Last suggestion, this is a kids bike maybe some fun colors?

My 4 year old boy was 40'' tall on his birthday. With the seat all the way down, and the handle bars adjuted in, the bike fits hime perfectly. This is our second premium 16'' "mountian bike." My older boy had another brand. This bike is light years ahead of our old one. Aeronomical frame lets him in and out of cockpit easily. Nice length to the crank allows him to go fast enough and easily ride uphill, and you can tell the pedals are for a kids bike. They are bigger than his first bike and smaller than mine, perfect. The handlebars have multiple settings to pull the bars closer to the rider and the brakes! Awesome brakes! It is so hard to walk the line of tiny hands being able to pull them, and still deliver enough stopping power. This bike does it. He made the transition from coaster brakes to hand in 30 seconds. He is actually much better at the hand brakes then coaster. Then the Specialized Logoed tires are so cool. This bike made my boy a better rider. Just buy it!

My 3 year old is 40 inches tall with a long torso and shorter legs and can rip around on a Strider, but the Jett is still to tall for him to sit on the seat and touch the ground with his feet even at the lowest position. That makes learning to ride it nearly impossible in our experience. I'm sure it will be better once his legs are taller than 19-20 inches. With only a 16-17in stand over with a diaper in the way we probably need a few weeks to learn to ride or to wait for a leg growth spurt.

Cool bike. Seems like a good middle ground which has good features, decently light weight and at a good price. I would recommend, but for other bikes in this category the seat height is a bit tall for a new rider which is about 19.75 inches at the lowest. My son was in the recommended range at about 39 inches tall, but would not be able to touch the ground. No body can learn how to bike if they can’t touch the ground. I bought a mini pivotal race seat and post and with that it’s 18 inches off the ground. With being advertised as a beginning bike that will grow with your child, it seems to lack the capability for the earlier riders. Again nice bike as long as you know the most important part of a first real bike is if the seat can go low enough to learn how to bike

Prompt delivery and everything as expected

Perfect bike for my 4 year old grandson. The quality is top notch and he will get a couple of years on it as he grows, the the little sister will get it and he will move on to the 20 inch Specialized. And did I mention he loves it.

Great bike, very nicely made. But too big for my 4 year old that is 39". His feet do not touch the ground. Now we have an expensive bike that can not be used.

Was a little bit smaller than I anticipated but still a very well built bike. The components and quality are exactly what you would expect from specialized and the price point made it a no brainer. The kid LOVES it as her first bike without training wheels.

This is a nice little bike but I have been frustrated in finding a pair of training wheels that easily fit. I'm here to save you the headache ... just order the Wald 10252 set.

This one here fell from Heaven! BD (((Random Act of Kindness))) My neigbors boyfriend gave me this bike brand new with tools & tags attached! My 6 year old grandaughter learned how to ride on this bike. Had it over s year now with no issues. Peddling is easy & handles great! She's outgrowing it and will be time for the little cousins to learn & share this beauty! I highly recomment this bike.
