Specifications
Brand

Powerfly+ 4 is an adventure-ready electric mountain bike that won’t break the bank. It’s designed to explore any terrain, from demanding commutes to easy singletrack, thanks to a durable aluminium frame, an SR Suntour suspension fork that smooths out bumps, and a smooth-shifting 10-speed Shimano CUES drivetrain. A powerful Bosch motor and a long-range 800 Wh battery give you the support and confidence to ride even further.

New RIB 2.0 battery
The removable integrated battery (RIB 2.0) is easy to take out of the bike for more convenient charging or travel. With an extra safety catch, you don’t have to worry about it dropping to the ground.

Extend your ride
Want to go even further? Then equip your bike with the 250 Wh PowerMore range extender battery, so you can take on even the biggest adventures.

Light, quiet, powerful: can be increased up to 100 Nm
The Bosch Performance Line CX motor has 85 Nm of torque, which can be increased via the Bosch eBike Flow app up to 100 Nm and 750 W. The all-new Bosch CX motor is lighter, quieter and even more powerful, while still delivering natural assistance for tackling very demanding rides.

Huge range for epic rides
The new 800 Wh Bosch battery delivers massive range for taking on the biggest adventures. Or it can be swapped for a 600 Wh option for a lighter ride with more agile handling.

Customise your bike to your needs
Powerfly-specific rack and mudguards integrate neatly and boost practicality, so you can tailor the bike for everyday needs or demanding expeditions.

A better way to make aluminium
In 2024, we began replacing high-emissions aluminium in production with low-emissions aluminium made using renewable energy sources. Since October 2025, we’ve been making almost all of our alloy bikes, including this model, using this new method, resulting in a significant reduction in our carbon footprint.

Bosch eBike Flow app
The new eBike Flow app makes every ride exactly the experience you want. Set the motor support level, track ride data and connect it with other apps like Strava and Apple Health. It also includes handy features such as navigation and maintenance reminders.

Shimano CUES
Shimano CUES is the answer to riders’ demands for a hassle-free drivetrain with long life and high performance. It’s versatile and durable, and designed for a wide range of electric and standard bikes. The CUES drivetrain features Shimano’s new LINKGLIDE technology, which significantly extends the lifespan of wear parts such as the chain, cassette and chainring.

Shimano LINKGLIDE
LINKGLIDE technology, with incredible durability plus smooth, positive shifting, guarantees a great pedalling feel. Available exclusively with Shimano CUES drivetrains.

Don’t forget the pedals
This bike doesn’t come with pedals, because you’ll get a better ride on your new bike if you choose the pedals yourself. Check out our pedal guide and pick the ones that match your riding style. We recommend road clip-in pedals for better control and performance.

TREK is headquartered in Waterloo, Wisconsin. The family-owned business was founded by Richard Burke in 1976, starting out in a small steel bicycle factory with just five employees. Within a few short years, the company caught on to bicycle trends and continued to grow. In the early 1990s, it began producing bicycles in a then-new material - Carbone.  Today, TREK sets the trends in bicycle development and is also considered a leader in the processing of Carbone. Its proprietary processing technology, called OCLV, has been applied in production with many innovations for more than 17 years. TREK bikes have celebrated success at major world races and have been associated with names such as Lance Armstrong, Alberto Contador, Chris Lieto, Roland Green, Chris Eatough, Andrew Shandro and Travis Brown. TREK is a premium brand you can always rely on.
