I bought my Motobecane Bistro 8V a couple of years ago. I was apprehensive because the price seemed to low to be the real deal. Happily, it is the real deal and I'd buy another bike from them in a heartbeat. It was shipped quickly and was delivered undamaged. I recall contacting their support team and had no problems with them at all.
I'm pretty handy with tools, so setup and adjustment were easy. I'd say that the only downside is that assembly and adjustment. If you're uncomfortable doing that you should consider buying from your local bike shop or find a bike mechanic to do it for you.
