They are heavy as I don't know what. 1 piece crank. That being said, it feels like the adult version of the cheap bmx bike your parents bought u when u were a kid that u rode the tires off of. I wish it came out pre-winter because for 200 bills isn't too bad for a winter/bad weather beater but in Chi, the winter's over but we still have plenty of bad weather to look forward to. But that's all that I would use it for. This is definitely not a main ride bike. Personally I like the fact that it's heavy, it has that feel that u could just dent and ding the heck out of it.
