3 Series


3 Series is your weekend trail bike, your workday commuter, or both. Versatility, great suspension, smart spec… it's no wonder 3 Series is the world's best-selling mountain bike.

Can't decide between a trail bike and a commuter? Get both, in one bike. 3 Series gives you upright confidence, control, and road-to-trail versatility, wherever you ride.



  1. Light, tough frame

    Trail-ready Alpha Aluminum frame is rack and fender ready for daily practicality.

  2. Perfect fit

    Our extended size range guarantees a better fit, so you get a better ride.

  3. Quality components

    Shimano drivetrains and Bontrager components mean smooth shifting and performance you can count on over the long haul.

  4. Limited lifetime warranty

It makes this rookie feel like a pro! I fell in love with my Trek 3000 Series the day I got it home. At this price, the bike is virtually a steal with all the value that's packed into it. I can't seem to recommend this bike enough. I love it so much.
