Mine is a Golden Buzzaround Lite, one of the really little ones. Its a 3 wheeler and breaks down into 4 pieces, the heaviest of which is only about 20 pounds, and it fits into a very small (Toyota Matrix) trunk or hatch space. I have an auto-immune arthritis, which is degenerative, and if I have to, I can assemble it myself, as can my 11 year old.
I use mine pretty exclusively at the parks - sometimes at the malls, or Home Depot, or if they have me teaching in a building on campus that is not where my office is located, for instance.
It does have a smaller battery, but it is very, very easy to charge. I plug it in when I stop for lunch (just ask me, I have a list of about 25-50 locations per park - someday I should probably write them up formally, huh?). Last week, though, I was there for the Food and Wine Festival and thus didn't stop for lunch and the battery didn't start flashing till I was at SE on the way out of the park - needless to say I made it to the car with no problems!
It comes with a front basket, but mine kept coming loose, so for $15 I got a back basket, and I like it SO much better! It holds much more, and I have much better vision! I mounted a light where the front basket used to be and now getting out of the parks after dark is easier as well.
I do have a spare battery, but for some reason, the original one is still running strong, and I've never needed the other one, but we do keep it regularly charged and use it from time to time, just to keep it fresh.
I don't know what other information would help you, but if you have any specific questions, please let me know and I'll be happy to answer them!
