820 is an excellent entryway to a world of off-road adventures. It's the most affordable mountain bike in our lineup and the ideal choice for beginners who are interested in the MTB life but also want a hybrid bike that's as equally suited to light trails as it is to potholed city streets.

It's right for you if...
You're ready to try mountain biking to see if you fall in love, and want a bike you can ride wherever you choose. You plan to ride all types of terrain, from city streets to gravel paths and light singletrack.

The tech you get
820 has a strong steel frame, a reliable 21-speed Shimano drivetrain, 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, and more.

The final word
820 is a great bike for anyone testing the waters of off-road riding. It's versatile, durable, and works well on rough pavement, light trails, and more.

Why you'll love it
- 820 is a great bike at an even better price, and it lets you explore off-road riding without the giant price tag that comes with higher-end mountain bikes
- The high-volume mountain bike tires and suspension fork take the edge off rough roads and trails
- Rack and fender mounts make it easy to accessorize, so your mountain bike can double as a rugged commuter
