I bought a Thruster at Walmart for $79. adjusted and greased everything. Rode it for almost 2 months. I am 6'3" 210#. The frame was a little small but, every thing was fine. Zero problems. I just do not like 700c tires. I want to like 700c...but I cannot convince myself. Trust me, I have tried over and over.
Sadly, I returned it. It is still there and I look at it every time I am in the store.
