Why Trek?

Bosch

Simplicity is key

Electric bikes are the most fun when you’re focused on the ride and not the controls. Marlin+ is built around that idea – the bike is loaded with technology that disappears underneath you when you’re riding, so you don’t have to fuss with settings and can just enjoy the ride.

AUTO mode adaptive motor support adjusts assistance level automatically while you ride to help you stay in your flow. It recognizes speed reductions and tweaks support to match, so you’re always riding with just the right boost.

An internal Bosch CompactTube 400 watt-hour battery is fixed in the downtube, where it’s clear from the elements. Its high energy density allows for a slim and sleek profile, while an easy-to-use charge port makes topping it up a cinch.

The Purion 200 remote gives you all the data you want with a bright color display that clearly shows your battery life, range, and speed. Simple controls let you change display data and power up your ride.

Your favorite bike goes electric

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!

Take on the rough stuff with a 120mm suspension fork, dropper seatpost that lets you move around, and stiff front and rear thru axles that keep handling precise. Button that up with trail-ready MTB geometry and you’ll be ready to cut loose on the dirt.

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.
