Honestly, it's a matter of bolting the front rotor to the wheel, attaching the wheel to the fork, and bolting the brake caliper to the fork. A total of like 8 bolts which it took me all of 15 minutes in my dining room to get it assembled. The derailleurs and everything already seem to be set right so very little adjustment is required.
A couple of things to watch out for:
1. In an effort to save weight, motobecane uses a 10 speed cassette from a road bike and it has 11-28 gearing. This is not ideal if you plan on going up anything fairly steep. I noticed i was having trouble climbing hills and thought it was because I was out of shape, but then i saw the 11-28 in the specs. I AM out of shape, but the gears dont help. I already purchased a new 11-36 cassette to swap in.
2. The tires are some super lightweight, skinny, low rolling resistance, treadless things that really offer no traction in anything but dry hard-pack. I unboxed the bike, saw the tires, and bought a set of 2.25" Maxxis ardents before I even rode the thing because you could tell they will suck in all but ideal conditions.
