I have one. Bike E was a good brand, innovative and extraordinary for their time, the 1990's to early 2000s. They kept cuttting prices to sell more units, and worked themselves into insolvency, IIRC. Good well featured bike. The AT is the best model to own, because of the rear suspension. That is a Cane Creek (Dia Compe?) unit that is an air shock. I filled mine with a tire pump, although you should use an air shock pump. I'm also thinking about getting a 20" fork and taking that 14" wheel to 20". I might also suggest casting about for a converter stem, a unit made for this bike, so you can use any old handlebars as the gerbil bars welded to the original stem are simply too short for the sort of handling you would want on such a cycle. It has a threadless headset (Ahead), so check that plastic bushing that comes down atop the stack. Very few proprietary parts on this, so it is easy to service. This bike is no speed demon, nor would you want it to be, with that 14" front wheel. It is heavy, but not inordinately so. Worth the trouble at a bargain price. Let me know if anything comes up.
