My nephew loves this bike! I bought this bike to him for his birthday gift.We assembled the bike together.It was very intersting.You need to assemble 3 parts by yourself:front wheel,pedals and handlebars.We met some problem while we assemble the handlebars, I ask the customer service and they sent me an instruction video,we watched it and finally solved the problem!The bike looks cool when we finsihed it! When my nephew rode it, his friends are also excited and want to try it!Anyway the bike worth the money,at least it is better than the one you can get from walmart??????The bike came in an complete box but the box is a little damaged by UPS.Fortunately there are protection pieces and cardboards works so the bike is not damaged.
