The bike path along the river is flat, enjoyable ride but there are some road intersections to watch out for. Pauwlins road is two lane road, the shoulder varies but not much traffic so that should be fine. Pickering Rd two lane not much of a shoulder in places but not much traffic either -passes through some nice farmland some short hills. Rt 23 out of Phoenixville more traffic, generally a shoulder and straight road so you should not have any problems. You can also take Rt23 through Phoenixville not much of a shoulder in places but the lanes are well marked. I think Pickering Road is the better option. No experience beyond 23 west.
