Because of the metal skin they have to add airbags and now a radio because without wind noise, everyone gets bored. Eventually they realize that the bike has become to heavy for just 1 person to hold up so they offer 2 additional wheels to help distribute the weight and stabilize the bicycle during turns and we have the latest rendition ...

The renamed, re badges 4 wheel bicycle, which they call the car, because it is still fresh in the consumers mind ...
