Easy to assemble and convert.Came with Chrome handlebars not the black ones also had no tire valves Schwinn needs to step it up With their quality control it's poorGot this for my 3yr old and he loves it! Very sturdy and easy to ride.This toddler bike is beyond cool. It’s pretty lightweight and very sturdy.PROS: Sturdy. Lightweight. Durable. Pretty Easy to assemble. Easy to change from tricycle to stride bike.CONS: My only complaint is that the instructions are terrible. The bike comes with bolts and screws and Lugnuts. I had left over screws. However, nowhere in the instructions does it tell you where any of these pieces go. Thankfully this trike is similar to my sons. So I was able to figure it out and to put it together pretty quickly.We bought this bike for my moms house as that’s where my son goes every day. It’s so easy to put together and rides great. We then went and got a second one for our house.Great bike. The stickers I was not expecting it to come with were cute for my son to participate with the easy build. The stickers came off though. It’s an easy way to transition from a tricycle to a bicycle. Definitely buy if you want your child to independently learn.This multi bike is really nice. To assemble is easy, didn't need the instructions but we had an issue with the seat falling down when say weight was placed since the clamp was not securing. Customer Service provided a new part and it has worked out great. The color is vivid, the feel of it seems sturdy so I can see our little one enjoying this for a while. My only complaints are minor....1) the bell is terrible. I would have much rather the one with thumb trigger you press then it retracts back. This one is a little frustrating for a toddler to try and concentrate while riding. 2) the wheel caps stick more than I care about.This trike is way too large for a two year old toddler! There is not even close the adjustment to lower seat so pedals can be touched let alone pedaled. By the time my grandson is able to reach the pedals with seat all the way lowered he will be riding a bicycle! Poor adjustability! Very disappointed that you list this as fitting a 2-4 year old !
