This bike was designed to be ridden on pavement. That's how you can go 15 MPH. I don't have pavement where I live so I am forced to ride it in my backyard. It still runs well on grass, gravel and rough surfaces.
This bike is easy to make portable. It weighs about forty five pound and can be put inside of a car trunk. I do that sometimes. To ride it on pavement to really get the adrenaline pumping.
Inside the box, the bike comes with the bike (Of course). And with the front fender. It needs to be put on before riding. I think now it comes with that assembled already. It comes with decals too. It has a charger and it needs to be charged twenty four hours before use. The handlebars must be fixed before too. Move them to any position that you like and tighten them.
