Lightweight, quiet, powerful: Upgrade to 100 Nm possible
The Bosch Performance Line CX motor delivers 85 Nm of torque as standard. Using the Bosch eBike Flow app, this can be increased to 100 Nm and the power output to 750 watts. The new Bosch CX e-system is now even lighter, quieter, and more powerful, supporting you on your most challenging adventures with natural propulsion.
Enormous range for epic rides
Bosch’s new 800 Wh battery ensures that your most exciting adventures don’t have to end prematurely, while the lighter 600 Wh battery option reduces the overall weight of the bike and allows for more agile handling.
Customize your bike
The mudguards specially designed for the Powerfly and the seamlessly integrated luggage rack increase the practical value of the bike and allow you to customize your setup to your daily needs or epic discovery tours.
Bosch eBike Flow App
The new eBike Flow app transforms your ride into a personalized experience. With it, you can adjust the motor’s assistance to your needs, track your ride statistics, and integrate your data with apps like Strava and Apple Health. It also offers practical features such as navigation and service reminders.
Active Braking Pivot
Active Braking Pivot allows our engineers to fine-tune how the suspension reacts independently to acceleration and braking forces. This gives you more confidence in critical situations.
A better method of aluminum production
In 2024, we began phasing out emissions-intensive aluminum from our production and replacing it with low-emission aluminum produced using renewable energy. By October 2025, nearly all of our aluminum bicycles – including this model – had been converted, resulting in a significant reduction in our carbon footprint.
Shimano CUES
Inspired by riders’ demand for a reliable, durable performance drivetrain, Shimano CUES offers a new level of versatility and resilience for both e-bikes and non-assisted bicycles. CUES features Shimano’s new LINKGLIDE drivetrain technology, which significantly extends the lifespan of wear parts such as the chain, cassette, and chainrings.
Shimano LINKGLIDE
LINKGLIDE technology was specifically developed for outstanding durability and both smooth and precise shifting performance – and of course, for a great pedaling feel. Exclusively available on Shimano CUES drivetrains.
