Electric stateboards (e-skateboards) typically cannot go over the same types of terrain that a onewheel can. Onewheels have large go-kart tires that overcome most obstacles. On a skateboard, even small rocks on the street can cause you to fall over your board. Its not necessarily called a nosedive with a traditional board however because of the smaller tires, there's potential to getting caught up on some object which can send you off the board. Get a Onewheel and enjoy the added terrain possibility along with the incredible float like feeling you get from riding.
