1. yes the reviews are good, the bike is a very good trail centre machine, but considerable cash is spend with the magazines on advertising, so read into this yourself
2. it is quite active if you run a lot of sag, not a problem with a pro-pedal or swinger shock, but its a 5.5inch FS'er and not a anthem, any bob i get doesn't bother me
3. i reckon around 66 to 66.5 for the 2010 frames, the geometry for the Five AM is on the webshite
4. about 30-31 lbs
i don't work for orange BTW but ride several different ones, ultimately you should test ride one, don't make an expensive purchase off the advice from a webshite…
