Welcome to C&V. I apologize for my comment. Of course a troll could be a brutish or ignorant beast. In English trolling is also a method of fishing, typically dropping a line in the water from a slowly moving boat and seeing what bites. That's the usual meaning in a forum, someone tossing out a piece of bait for sport and waiting to see who bites.

Speaking of biting, it is good that you didn't bite at a bike which doesn't fit. You have a limited budget, but neither of those bikes would be especially high performance. They would be good for utility transportation, but you might eventually wish for something better. Good luck in your search.
