- Confident disc braking means bad weather doesn't have to keep you from enjoying your ride

- It's easy to accessorize with racks, a kickstand, fenders, lights, and more!
- Like every Trek hybrid, it's backed by a lifetime warranty and supported by a wide network of retail partners
A better way to produce aluminum
Starting in 2024, we began removing high-emission aluminum from our manufacturing and replacing it with low-emission aluminum made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.
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.
