This Marlin 5 Gen 3 mountain bike is rated as an Excellent Grade, which reflects that the bike is in very good condition and can be considered to have been 'pre-pedalled'. Having been lightly used, there are some signs of use on the bike. The only minor visible marks are on the drive side top tube and on the kick stand mount.

To ensure this bike meets our high standards for quality, it has undergone a thorough inspection by our professional mechanics. As with all our bikes, it comes with a 12-month Tredz warranty, plus any additional manufacturer warranty which may apply.

It features a trail-savvy frame with a suspension fork, 9-speed Shimano CUES shifting and mounts for a rack and kickstand that make it an ideal choice for trail riders or anyone looking for a comfortable, stable commuter with the ruggedness of a real mountain bike.

Will my bike have a curved top tube?

Smaller frames have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frame sizes have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.

Fit for every rider

Marlin comes in seven frame sizes to suit riders of any height, and Smart Wheel Size ensures you’re on the fastest wheel that fits. The smallest sizes even come with short-reach brake levers and narrower handlebars that give smaller riders better comfort and control.

High tech, high value

Marlin looks and feels great. It’s packed with features usually found only on more expensive bikes, like a stylish frame with internal shift cable and brake hose routing, which can help your cables last longer by protecting them from the elements.

Shimano CUES

Inspired by rider demand for trouble-free drivetrain longevity and performance, Shimano CUES offers a new foundation for versatility and durability across a range of both electric and standard bikes. CUES features Shimano’s new LINKGLIDE drivetrain technology for significantly increased life on wear items like chain, cassette and chainrings.

Shimano LINKGLIDE

LINKGLIDE technology has been specifically engineered for incredible durability while still delivering smooth and decisive shifting – along with a great pedalling experience. Available exclusively on Shimano CUES drivetrains.
