I was looking at the same two bikes, and ended up with the Forge (a $200 Amazon Gift Certificate pushed it over the edge). most people on here didn't seem to care for the Diamond Back. (even though I like the looks of the frame, the box design is quite cool looking). The other bike I looked at was the Ibex Alpine 450... which has better components than the Responce (but cost is $100 more). The Forge has even better parts.lawnbike said:bikes Forge 5xx vs. diamondback response(base) Both I can get for <$300.00 locally.Thoughts on decision??
