New to china bike

[ttr]

My wife surprised me with an 05 Zongshen for Christmas. I'm planning on riding it to work (2 miles) It looks like a good enough bike. I've tightened just about evey bolt on it, and i changed the oil. It has only 27 miles on it. I also changed the rear sprocket from a 58 to a 48, it came with it so i figured what the heck. What can i expect owning a Zongshen?

I live in N.E. Oklahoma
