The Marlin 5 is an everyday trail bike that’s excellent for daily adventures on paved and unpaved roads. It features a trail-ready frame with a suspension fork, a 9-speed Shimano CUES drivetrain, and mounts for a rear rack and kickstand. That makes this bike the ideal choice for anyone looking for a comfortable, stable commuter bike with the toughness of a real mountain bike. Does my bike have a curved top tube? The smaller frames have a top tube that curves downward toward the seat tube. This design creates a lower standover height, which is handy for smaller riders because it makes it easier to stand over the bike. The larger frame sizes have a straight top tube because standover height is usually not an issue for taller riders. Fits every rider The Marlin is available in seven frame sizes, so people of every height can find one that fits. Thanks to Smart Wheel Size, you get the fastest wheel that fits. The smallest sizes even have shorter brake levers and narrower handlebars, so smaller riders experience more comfort and control. High tech, attractively priced The Marlin looks great and rides great. It has all kinds of features you’d normally only find on more expensive bikes, such as a stylish frame with internal shift cable and brake hose routing, which helps your cables last longer because they’re protected from the elements. Shimano CUES Inspired by riders’ request for a drivetrain with worry-free long life and quality, Shimano CUES lays a new foundation for versatility and durability across a range of electric and traditional bikes. CUES features Shimano’s new LINKGLIDE drivetrain technology, which makes wear items such as the chain, cassette and chainrings last significantly longer. A better production method for aluminum In 2024, we started phasing out high-emission aluminum in favor of a more sustainable alternative based on renewable energy. As of October 2025, almost every aluminum bike we make is made from low-emission material, resulting in a huge reduction in emissions. Shimano LINKGLIDE The LINKGLIDE technology was specially developed to keep shifting incredibly smooth and decisive for a very long time. It also lets you pedal comfortably. Exclusively available on Shimano CUES drivetrains.
