I grew up in Lyndhurst on Sanford Avenue just a short walk from the Lyndhurst Diner. Not much riding in your area, but if you're on the ATV, I'm sure you're hitting up the Meadows. I used to rip it up there on my dirt bike back in the 80s. I've tried it on the MTB but it doesn't quite cut it. Most fun I had on a bike in Lyndhurst was the BMX track we used to have down in the park by Riverside Ave. We used to make killer double jumps, tabletops, huge turns. On a good day we'd have 20 kids there dicing it out on the track. Good times. Good luck on the MTB.
