Just my opinion about 3G bikes. They were innovators and cutting edge bicycle designers in years past. I think they got themselves into a bit of financial trouble and at some point were not able to/or didn't ship parts/bikes that were ordered. There were some unhappy customers - this goes back to the years of chopperbicycle.net Take a look at the bikes and you will see all the same cookie cutter foreign made bikes you you can buy from Micargi or some similar company. Yes, some of the parts that are company specific might be cool on an RRB, but my opinion is, until I hear different, that I would not send them .02.
Good luck if you order and let us know how you make out.
