Oh god yeah. Take Bells Line of Road, then navigate your way onto Wiseman's Ferry Road. Take the old road down into Woy Woy (turn right at the Shell Servo on Kariong Hill). About 5 hours of pure driving pleasure. Once you get to Woy Woy there's only desolation I'm afraid. And a few wild boar.

BUT If it's bike shops you are going to have a look at use yellowpages new map based search before you go. Click on 'Map-based Search' tab, enter Suburb: Woy Woy Business Type: Bike, then pick the right options. On the map you can hover over each shop to get details. Very cool.
