Just out of curiosity, I weighed it just now. Fully assembled, components, wheels, and all (including my saddlebag mount that I added) is 41 pounds. So yeah, that's pretty heavy. It's better than walking for sure though. I guess that explains the comfortable ride on rough trails.

Drivetrain is Shimano, everything else is generic. Nothing's broken yet. (but I'm getting worried about the chain's condition.{stretched about 1/16" per 12 links now. Due for a replacement after this winter, I think.)
