All i can tell you Bill is a lad i know got one, his idea was to use it as a trike (although it will have 4 wheels) and then when he fancied convert it back to a bike, however, he had some issues with the insurance company as they scratched their heads on what category it came under. In the end they agreed to treat it as a trike but on condition it remained a trike at all times. If you require i can maybe sort out a contact for you, the lad lives over in Cumbria
just remembered as well, when he started using it he found it very daunting as they tip a little, what he did was modify his with 2 bike suspension units to stop it from tilting, acting more like a trike
Sean's dad had one out in America, we rode with them when it was fitted, it did lean a little in bends, but not so much as to be concerned about. In the end he sold it and bought a full blown trike.
I am sure SBinSC will give you more info on what he and his dad thought of it.
My dad had a Voyager kit, like TowPac but bigger wheels. A little fiddley to mount initial hardware, but not too bad, and once fitted easy on and off. It worked fine, but was a bear to steer, as most trikes are unless front end is raked.
Bottom line is, if you want a trike, buy a real trike. Or at the very least, get your front end raked. (EZ Steer kit)
