It takes about 5 minutes to assemble it out of the box because all you have to do is attach the handlebars. Mine came about 75% charged up already so we could use it right away.
This thing is pretty sturdy, it's super simple to control, has a headlight on the front, and is just all around everything you'd want from a kick scooter. The upper weight limit is 260lbs so adults can ride it too, meaning a family could share it. It folds down for easy transport too and is not very heavy. It recharges from a simple wall outlet.
So I hope that helps you make a decision. I was pleased with the one we got and if I needed another kickscooter this would be the one I would get.
