You need protection between the steering wheel and where children sit. You don't want them to get their hands on the bars and lose their fingers. Other than that, I think it's an extraordinary production. I've always manipulated old bikes and scooters to create electric vehicles. It is an interesting idea and will bring many fun moments with the family. The seats are removable so you can take the bike apart for painting and easier maintenance. It is important to put protection between the seats and the tire to prevent accidents.
