The Marlin is Trek’s most popular mountain bike and a best-seller here at Bay Cycles. It’s a hardtail mountain bike, so a reliable suspension fork is paired with a simple and well proven aluminium frame. Now in Gen 3, the Marlin 5 has a fully evolved frame that’s packed with neat details.

The Marlin 5 uses Trek’s Smart Wheel sizing. This means with wheel sizes increasing proportionally along with frame sizes, so every rider gets the fit they need. Trek bucks the trend and offers eight frame sizes, so whether you’re under 5’, over 6’5”, or anywhere in between, you’re guaranteed a great fit.

Like all Trek bikes the premium build quality and finish is a notch above many brands and we assemble your new machine with care and precision. Our staff will ensure you get the correct frame size and your bike adjusted and dialled in for a perfect fit.

Our Verdict: The Trek Marlin 5 is a premium hardtail mountain bike that will boost your confidence on off road trails. It’s versatile too, so commuting through rough urban streets, or heading out on a bikepacking adventure are all within the Marlin’s abilities.
