I'm still deciding but I like the idea of a trailer instead of panniers, although as I don't have experience and I don't know the pros ans cons of each. But I like the trailer because you don't put the weight ON the bike so that would allow me to go for a more lightweight bike.
Nice questions Robow I guess my final decision should be after I test ride each one.
Also I noticed that the Scott Sub and Giant Escape are more stretched out in their geometry and has a longer chainstays as Bezalel said. What impact does this geometry has on the ride oppose to the others bikes?
