The Marlin 4 is a versatile mountain bike that confidently handles all adventures – both in everyday life and on the trail. Its trail-ready frame with suspension fork, the 8-speed Shimano ESSA drivetrain, and the mounting options for a rack and kickstand make it the ideal choice for trail riders and anyone looking for a comfortable, stable commuter bike that boasts the robustness of a true mountain bike. Does my bike have a curved top tube? Smaller frames have a top tube that curves downwards just before the seat tube. This design results in a lower standover height, making it easier for shorter riders to get on and off the bike. Larger frames come with a straight top tube, as taller riders generally don’t have a problem with standover height. A 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. Lots of technology, attractive price The Marlin not only looks great, but it also rides superbly. It’s packed with features usually found only on more expensive bikes, such as the stylish frame with internal cable and brake hose routing to protect the cables from the elements. Shimano CUES Inspired by riders’ demand for a reliable, durable performance drivetrain, Shimano CUES offers a new level of versatility and resilience for both e-bikes and non-assisted bicycles. CUES features Shimano’s new LINKGLIDE drivetrain technology, which significantly extends the lifespan of wear parts such as the chain, cassette, and chainrings. Shimano LINKGLIDE In 2024, we began phasing out emissions-intensive aluminum from our production and replacing it with low-emission aluminum produced using renewable energy. By October 2025, nearly all of our aluminum bicycles – including this model – had been converted, resulting in a significant reduction in our carbon footprint.
