Marlin+ builds off the same platform of our most popular Trek – Marlin. That means you get the same confident handling and versatility as traditional Marlin but with a little boost!
Does your ride keep rolling beyond the trail? Marlin+ is ready for full customization for cruising the town. Rack, fender, and kickstand mounts let you add on all the gear you need on commutes to the campus or office.
Your safety matters on every ride — that’s why we set our standards sky high.
Every Marlin+ is backed by Bosch and Trek, so you can count on it to exceed safety standards. And because every detail on your bike is important, we’re here to get your Marlin+ is dialed for you as soon as it’s unboxed. You never even have to lift a wrench.
