Powerfly+ 4 800Wh

Removable Integrated Battery (RIB 2.0) makes it easy to remove your battery for more convenient charging or travelling, and you don’t have to worry about dropping it thanks to a secondary safety catch.

Wanna take your ride even further? Pair a 250 Wh PowerMore range extender with your bike to chase your most epic adventures.

Bosch’s Performance Line CX motor has 85 Nm of torque out of the box but can be tuned all the way up to 100 Nm and 750 W of power using the Bosch eBike Flow app, the all-new Bosch CX motor is lighter, quieter and now more powerful than ever without wavering on natural-feeling support for crushing epic rides.

Bosch’s new 800 Wh battery gives you enormous range for chasing down your greatest adventures – or you can swap to a 600 Wh option for a lighter-weight ride with more nimble handling.

Get more utility and sleek integration with mudguards and a rack designed specifically for Powerfly, so you can customise your setup for everyday needs or epic exploration.

Starting in 2024, we began removing high-emission aluminium from our manufacturing and replacing it with low-emission aluminium 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.

The new eBike Flow app turns your ride into a personalised experience. Use it to customise your motor's assist behaviour, track your ride stats and integrate your data with apps like Strava and Apple Health. There's even handy features like navigation and service reminders.Bosch eBike Flow app and associated features are not available in all markets. Check with your local Trek retailer for details.

Inspired by rider demand for trouble-free drivetrain longevity and performance, Shimano CUES offers a new foundation for versatility and durability across a range of both electric and standard bikes. CUES features Shimano’s new LINKGLIDE drivetrain technology for significantly increased life on wear items like chain, cassette and chainrings.

LINKGLIDE technology has been specifically engineered for incredible durability while still delivering smooth and decisive shifting – along with a great pedalling experience. Available exclusively on Shimano CUES drivetrains.

This bike doesn’t come with pedals because you’ll have a better time on your new bike if you choose your own. See the pedal guide to find the best pedals for your riding style. We recommend clipless road pedals for control and efficiency.

Weight limit

This bike has a maximum total weight limit (combined weight of bicycle, rider and cargo) of 136 kg (300 lbs).

To measure your height, stand up straight, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.

How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inside leg measurement. Your inside leg is very important to your final bike size so please measure carefully.
