It was relatively warm, and I took my xmart bike out today for a ride. Not bad at all. I did abuse it a bit off-road, but the rough handling didn't seem to bother it. It handled it quite well.
However, I did notice a knocking noise coming from the bottom bracket. It only happens under pressure or when going uphill. I am guessing it may have a bearing or two missing. i need to open it up when i get the chance. Other than that, it handled great.
