"Look fast, feel fast, go fast."
"Unlike some bikes on the cheap end of the spectrum that cater to the recreational user, this one is aimed firmly at entry-level riders who want a bike that's affordable yet capable of riding and racing hard."

Load up. Or not.
Whether you're after a lightweight singletrack shredder or sticking to the pavement on your commute to work, Marlin is compatible with all the gear you need to have a great ride.
Shop nowWill 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.
Suspension lockout
Locked suspension means your fork remains inactive, increasing pedalling efficiency. Perfect for extended road sections where efficiency is more important than bump absorption.
Rack mounts
Going for a long ride? Rack mounts make carrying accessories a breeze.
Blendr stem
Bontrager stem technology lets you clip your gear directly to the stem for clean looks and maximum user friendliness.

Internal cable routing
We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.
Rear kickstand mount
Chainstay mounts make it easy to install a rear kickstand that stays out of your way and supports bikes of all sizes. No more laying or leaning.
