Power to the pedal

Built to perform 

Since 1886 (you read that right) Bosch has been building technology based around two driving principles — precision and quality. Today, they make some of the most revered motors in the e-bike world. They deliver powerful, natural-feeling assist that’s backed with a global network of support that’s there for you no matter what.

Intelligent assist 

The Performance Line CX motor gives you 85Nm of torque to get you up steep climbs and accelerate to top speeds.
Choose from 4 ride modes depending on the level of support you want. The Tour+ and eMTB modes automatically adjust the assist based on your pedaling input and the terrain so you get predictable, natural-feeling power.

Our Removable Integrated Battery (RIB) system lets you pull your battery off quickly and easily. No awkward reaching under your downtube or digging in the toolbox necessary. 

Built to elevate your e-bike experience, Bosch’s eBike Flow app lets you take control of your ride. It works with both iOS and Android phones, auto-updates your remote and display with the latest features, and the home screen gives you a quick overview of your most important ride data like battery status and range. 

Customize your assist

Fine-tune assist modes to your liking. Get the most support on your climbs or stretch out the miles on longer rides with more efficient power use.

Set your record

Tracking starts as soon as your foot hits the pedal and pauses automatically when you take a break. Plus, your data synchronizes with integrated apps like Apple Health in real-time.

Tech built for Trek

Trek-exclusive integration means the eBike Flow app automatically recognizes your Trek e-MTB, provides service recommendations, and will even help you find your local Trek shop.
