Will 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.
Upgrade your pedals and love your bike more
Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.
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.
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.

We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.
