Nice bike- mine took about a week and a half from the time I ordered it to arrive. Assembly is easy, but adjusting the brakes and shifters can take some time. Once adjusted, it works very well- it shifts smoothly, and rides fairly easily. My complaints are these:
1) Comes with cheesy pedals- I replaced them with these (9/16" threads): http://www.amazon.com/Diamondback-Sound-Pedal-Black-Alloy/dp/B001C3GJ22/ref=sr_1_1?ie=UTF8&s=sporting-goods&qid=1284868963&sr=8-1
2) Brake levers are plastic, and the pivot point is a rivet, not a bolt. They feel a bit flimsy, but work fine.
3) The seat height is a bit low. I'm fairly average-sized (5'8"), and I have to raise the seat to the absolute maximum to be comfortabe.
4) The front wheel is ever so slightly warped- doesn't really affect anything, really.
Overall, a good bike for the price.

I didn't have much money for the summer so I figured I'd buy this bike. What a poor decision. Both wheels are not at all true, so using it is already hard enough. The grips on the handlebars will also slide off halfway overnight, every night. And the worst thing is just this last week, when I was biking on the road to work, the right pedal just came clean off, stripped, and I nearly got run over by the passing cars. How does that even happen on a bike. I will never skimp on paying a more for a bike from now on. I have only had this bike for 2 weeks and it has not been treating me well at all.

No problems with shipping. Installation was simple. The only parts needed to be installed was the front wheel, handlebar, pedals, and seat. Brakes also needed adjustment.

As for the bike, it is what you would expect for a hundred dollars. Cheap plastic parts, squishy suspension, heavy frame, very cheap looking derailer, and teeny-tiny handlebars covered in rubber.

Ride is ok. So far no chain issues with gear changes. Given how cheap everything looks, I don't know how long it will last. I have some buyer's remorse already, i am sure that for the money, I could have gotten a better bike used on craigslist or something.
