Sir; yes. Park and Rec. built two riding areas; that I'm aware of. One is at the corner of Camp Stewart and ??? I don't remember the name? I'll add; if I remember
► Renaissance Park, 8 miles of intermediate to advanced trails
1200 West Tyvola Road
There is a place in Concord I stumbled across. If you exit 85 at Poplar Tent (Exit 52) and go west the first street you come to is Goodman. Go north on Goodman. Back in there on the left is a park for mountain biking. I haven't been there but it looks pretty cool from what i have seen.
Lot's of good MTB in Charlotte, and the surrounding areas. My favorite place is Sherman Branch - almost 11 miles of fast, flowing single-track with many technical options. It's on Rocky River Church Rd., just off of I-485 & Albemarle Rd.
How hardcore are the whitewater center trails? I ride a cyclocross bike and am thinking about checking them out, but the thinner tires aren't a good match for some places.
