Marlin 4 is the perfect gateway to trail riding. It’s ideal for new riders who want a mountain bike with knobby tyres, that can double as a rugged commuter. Disc brakes, front suspension, 21 speeds and mounts for a rack and fenders make this a great bike for new trail riders and campus commuters alike.

Will my bike have a curved top tube?

Smaller frames (XXS, XS and S) 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. The larger frames (M and ML) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.

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.

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.

Rack mounts
