I bought an adult tricycle on Friday, and have been using it every day since to get around.
It's got 7 speeds, and I typically go up to 4th or 5th gear for cruising purposes. And once I get it paid off, I'm going to get an electric assist conversion for it. It especially helps me out since I can't get a driver's license and honestly don't want to get something I could easily kill someone else with.
