Valley forge park has some trails, not the paved loop but some that go through the woods. Of course an hour from center city gets you about 15 miles away, right. French Creek state park, near the morgantown exit of the pa turnpike has some good trails, that might be 1.5 hours.

I'm relatively new to MTB'ing and have never biked up at Wissahickon (although I've been meaning to get up there) but there are quite a few trails to ride near Brandywine Creek State Park and Woodlawn Nature Preserve in Wilmington (about 4 miles from me). This area is about 35 minutes from Philly too. Let me know if you'd like a more detailed description and/or help finding the trailheads.
French creek is great. There are a lot of trails and I have gotten lost there before. Find some trail maps if you can. Its definitely worth the drive and you can check out some other things in the area, like st. peters village, just east on rt 23, which also has some trails, and the creek is full of boulders that you can climb on.

Has anyone else ridden by the Delaware river (where Girard meets with the river) back behind some of the industrial buildings? Its where everyone rides their motorcycles and ATVs. I think its pretty fun.
My response would have been something along the lines of: "Does your bike have computer controlled suspension? Then shut your piehole, this baby is from the future!"
to many to list
Im gonna have to go there and have a look as I know exactly where that is gonna bring my friend Kimber though, might be some zombies around those parts theres a bike shop right around there called the "Bicycle Stable" 1420 Frankford Ave. the guys there are alright, and Im sure they wouldnt mind giving you the location of some sweet spots in Philly their#s 215 634 0633
