Looks like the 2 model uses large tubing and a different tire or fender. I have the original model and read many of the posts about it a couple of years ago. Many of the people that wrote about it were of the (yeah I put to much weight in it but it shouldn't have failed variety), never overloaded mine and never had any problems. it seems that the 2 model has a higher weight capacity 50 lbs as compared to 35 lbs. If full price 199 was the only option I believe paying 100 more for a BOB would be a better deal. It kind of depends what you are going to use it for and how often.
