Italtrike Tandem Tricycles

I love these red and orange tandem tricycles from Italtrike, makers of the fantastic looking OKO bike. The Carry tricycle has a slightly retro look, while the Pilot 200 sports a more contemporary design. Both can accomodate 2 riders. Now I don't know if these trikes would cause power struggles between kids who prefer to pedal rather than sit back as passengers, but in a perfect world where kids like to share and take turns, it would be a fun way to share a bicycle ride with siblings and friends.
