BikeRide finds and shows you the best prices of the bikes you want to buy. Prices constantly change and it’s impossible to compare them all yourself.

We search for prices on over 120 bike retailers to guarantee that we find the lowest prices – to save you time and money.

It’s a promise we stand behind: If you find a lower price on a bike elsewhere, we will sell it to you for 10% less. For example, if you find a bike for $480 that we have listed at $500, we will offer you to buy it for $432 through BikeRide. The bike must be the same color and size, sold in the US and not include the use of a coupon.

If you find a lower price, email us at [email protected] with documentation of the price. We’re committed to making sure that the cost of a bike does not keep you from cycling!

Summary of Reviews

We have read all expert and user reviews on the Trek Marlin Gen 3. In summary, this is what cyclists think.

9 reasons to buy

  • The Marlin comes in four builds, one with SRAM 1x12 (Marlin 7) and three with Shimano (1x8, 1x9, 1x10).
  • Highlighting the roomy frame and balanced riding position, experts agree the Marlin Gen 3’s XC geometry is its biggest strength versus other budget MTBs.
  • The long reach, short stem, and slack front end inspire confidence when descending, while the neutral riding position boosts traction on climbs.
  • Testers commend the Marlin's stable steering and ability to hold speed through tighter sections for a bike at this price point.
  • The Marlin 4 comes in seven sizes, and the other builds are available in six.
  • Reviewers praise the shift quality of Shimano’s CUES drivetrain (Marlin 5 and 6).
  • Experts applaud the thick rubber chainstay protection.
  • The Bontrager XR3 tires (Marlin 5) are durable, and the chunky tread provides plenty of grip, according to experts.
  • The Tektro hydraulic brakes (Marlin 5, 6) have plenty of stopping power.

4 reasons not to buy

  • The basic suspension forks and quick-release axles on all Marlin builds limit the bike's capabilities.
  • A tester of the Marlin 5 laments the SR Suntour XCT 30 fork’s sloppiness and poor performance.
  • Upgrading to a fork with a tapered steerer would require changing the headset bearings.
  • Without thru-axles or rear Boost spacing, upgrade options are limited.

Bottom line

The Gen 3 Marlin enhances Trek’s venerable budget MTB with solid XC geometry. Though the off-road performance can be impressive for the price, especially in the hands of skilled riders, all builds suffer from “underwhelming” suspension forks. The XC geometry works well on flowing trails and when descending, setting the Marlin apart from most budget MTBs. Trek’s new Marlin is a solid option for commuters keen to tackle trails on weekends, mountain bike newbies, and anyone seeking to sample off-road biking without investing too much up-front.

I really can’t understate how much the modern trail inspired geometry improves its performance on singletrack trails.

Test – Trek Marlin 7: Is It Enough to Have Fun? [Italian]

The Trek Marlin 7… surprised us in terms of geometry and construction, but a little less so in terms of its features. It’s… capable of accompanying you on your most adventurous and technical challenges… It’s a “cheap” bike, but with big-bike features!
