This Trek medium/large Mountain Bike 820 is an entryway to a world of off-road adventures. The ideal choice for beginners who are interested in MTB Life but also want a hybrid bike that's as equally suited to light trails as it is to potholed city streets. 820 has a strong steel frame, semi slick tires that roll well on pavement and trails, durable alloy wheels, and a suspension fork that takes the edge off bumps. Plus, it has mounts so you can accessorize with racks, fenders, lights, a fitness tracker, a kickstand, and more! It's versatile and works well on rough pavement, trails, or both. Backed by Trek's lifetime warranty.
