Hey guys, new to this forum. I just picked up one of these bikes for $20. I am looking to get into trail riding (nothing extreme) and I didn't want to drop a few hundred bucks on a bike to find out if I liked it or not, so I bought this (at the time not knowing it was a folder). My question about this bike is.. If I do get into it like I feel I will, would it be worth upgrading this bike with better components or just buy a newer one and be done with it? I would mainly ride this on packed dirt/grass paths that have some rough areas and also some pavement. The frame seems to fit me pretty well so thats why I'm asking, but if this frame just isn't worth upgrading I don't want to waste the time/money when I could buy something newer.
