During the 2020 pandemic, my wife and I both got new bikes and while I got more into roads and multi-use trails, she came to enjoy riding mountain biking trails with friends. The new(ish) trails at Southside Park offer a nice beginner trail and a longer intermediate trail that are both a great getaway for those that enjoy the activity but live in town.
You're looking for a nano here...though not your typical black magnetic type. Enjoy the hunt...and my apologies to the shorter folks out there.
