Here in Florida, you can get a Trike endorsement on your license that allows you to ride any three wheeled vehicle but not a two wheeled. You must have a motorcycle endorsement for that. The motorcycle endorsement allows you to ride either. We have a lot of old farts here who want to ride a motorcycle but are unable to pass the MSF test to get the endorsement.... so the state came up with the MSF trike classes and license endorsement.
The local classes use the GZ trikes. We have a couple of local companies that do the conversion. Not cheap, but if you want to ride....and have the cash, I say go for it.
