Hase Ketts can be hooked in tandem as shown in this photo. There is a connector which links the fork of the second trike to the frame of the lead trike. It is a terrific alternative for people who enjoy riding together, but want the flexibility to ride separately. Think of the possibilities.
We are stocking the Ketts so come take a test ride. We'd need some extra notice if you want to test ride with the trikes hooked in tandem. If you can imagine, the Hase people hooked 63 Ketts to establish a world record. Let's see a Kett is probably five foot long so 63 would streach the length of a football field. Think of the organization to get all those Ketts connected and all the riders on them at once. I don't want to think about it.
