Differences between quad and triple and other tips ?

[dave soi]

So i am planning to get a quad tandem at some point and was wondering if there is anything different to riding a quad over a triplet ? Anything unique to quads over tandems and triples ? i own both a tandem and a triple just wondering what a quad is like.

A quad like a ZEM 2?

A quad is longer than a triple. You will have to consider how you go round corners.
You will have to train your fourth rider!
