Transporting. It is not coupled. I have a suburban and plan to transport inside car. I have thought about an extended top rack but will first try inside my vehicle.
One of my main reasons for the triplet is the MS150 and some other local rides. The MS150 do not allow the trailer bike to make a triple out of a tandem. My 10 yr old wants to join with daughter and I for the ride. I figure with 5 kids down to two years old, I hope to have many years enjoyment.
Interesting side note: Mel said that typically a triplet is used by a famliy about 5 to 7 years and then sold. I hope I can beat that mark by about 5 additional years.
