820

Model 17027

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.

You're ready to try your hand at 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.

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!

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, or both.

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, fender, and kickstand mounts make it easy to accessorize, so your mountain bike can double as a rugged commuter

From transporting on a rack to fixing a flat, sometimes those wheels need to come off your bike. Keep watching to learn how to safely remove and install wheels that use a quick release system.

We reserve the right to make changes to the product information contained on this site at any time without notice, including with respect to equipment, specifications, models, colors, and materials.

Bike and frame weights are based off Trek pre-production painted frames at time of publication. Weights may vary in final production.

The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
