can't say much about the frame, but looking at the components, I'm not impressed.
I would sooner pay a few hindred more and get a good alu frame/cf fork with 105 stuff and a decent wheelset.
My guess is that wheelset will function until you get to 3K miles and then it'll just start coming apart.
Crankset/BB is lower level stuff, below Tiagra.
If you don;t plan to ride it much, it would prolly do.
But for a fact, any of the branded CF stuff (Spec,Trek,Cannondale, Jamis, etc) used, would prolly far out last this.
For $1100, this is like their $600 bikes with a CF frame...
The list of $2900 is a total joke - at best it's a $900 bike being sold for $1100
EDIT: Not knowing yoursize, My bet is that something like this will be heads above the Motobecane

and will prolly sell for way less than $1100, even with shipping
I'm sure there's prolly a bunch of nice stuff out there...
or this...
