I have been doing a little research and have come up with the following places here in PA that offer summer mountain biking (according to their website), so you may want to check them out. Some of them I am sure you have heard of before...
PA-------I was reading about Sawmill ski area, it says they have shuttle service but from what I have read they don't... However, they have a road going to the top of the mountain that you can ride up and then ride the slopes down... http://skisawmill.com/
PA--------- 7-springs is over on the western side of PA so you may want to check them out... According to their website they offer lift service for people and their bikes... http://www.7springs.com/summer_bikinghiking.shtml
PA--------- Blue Knob has a downhill course, but it says there is no shuttle service available... http://www.blueknob.com/bike.html

NJ----------Diablo freeride park is supposed to be the sweetest place around... http://www.diablofreeridepark.com/park_info.html
NY---------Another place is whiteface, located in NY, haven't heard anyone whose been there yet but it looks cool and offers lift service... http://www.whiteface.com/newsite/summer/mtnbiking.php
