"T(hr)andem" or "Modular Triplet"
This Triplet has a bit of a twist, it has S&S couplers so that it can be separated into sections, and it has a low standover height for an adult front and rear with a child in the middle
S&S couplers are fairly expensive, and all the kit on this bike is pretty high end. The nature of of children is that they change size very quickly, and won't always want to ride with their parents... so there is a bit of a two nang bikes for the price of one element to this bike, in that the middle section can be removed, to make a tandem!
This makes it idealy suited to the customers (very specific) needs and should prolong the usefull life of the bicycle by many years!
