I have the bike and it's all put together. I was supposed to get it Tuesday, but there was nobody home by the time the UPS driver got here, so I didn't receive the bike until Wednesday.
The bike and its parts were all very well packed by the people at BD. Plenty of foam and plastic protecting everything, and even a piece of plasic protecting the front fork. Spent 15 minutes just removing all the stuff.
The pedals, the seat, the front wheel, the handlebars, and the brake cables all came unattached. The pedals went on with no problem once I realized the left one had to be screwed on counter-clockwise! The seat was difficult to install and get just right with only two hands. The instruction manual that came with it was very vague, and I had difficulty interpreting how the handlebars were to be installed, but I figured it out. Also, the handlebars were twisted in the wrong direction in that the brake levers were facing towards me instead of away from me and down at an angle, so I had to loosen the top bracket and adjust the handlebars that way. Note: If you need to do that, be damn sure none of the housings are in the way and are getting pulled too tightly.
I was learning on the fly, so the total installation took an hour and a half. Also, the wheels were not trued, so I took them by the LBS to have them done professionally and picked them up yesterday. The guy at the LBS told me when I picked them up that a few of the spokes were as tight as a drum from the factory. Keep that in mind as far as BD goes, the wheel-builders could pay more attention to detail.
I finally have it all put together. The only thing missing are my lights for right now. Over the nest few weeks, I may also install a rear rack, a camera mount, and possibly a bike computer if I can find a bargain on one somewhere. I consider that a luxury, so until then, I will just continue to track my rides on my MapMyRide app.
In summary: Was it worth going the BD route? So far, I can say yes. I'd recommend brushing up on the mechanical skills and watching YouTube videos beforehand on the installation of the parts I listed above.
Costs so far: Bike (with tax, since it was an intrastate transaction): $423. Truing of both wheels: $32. Water bottle/cage/two Presta adaptors: $18. Total: $473
I'll post another review once I get a few miles on the bike. I snapped a few pics as well.
