Trek Powerfly+ 4 800Wh Gen 5 Dark Star/Supernova

Season:2027

Brand:Trek

Code:79355BLK

Powerfly+ 4 is an adventure-ready electric mountain bike that does not break the bank.

It is built to explore anywhere from rugged commutes to light singletrack with a durable aluminium frame, bump-smoothing SR Suntour suspension fork, and smooth-shifting 10-speed Shimano CUES drivetrain. A powerful Bosch motor and long-range 800Wh battery give you the support and confidence to go farther.

The RIB 2.0 removable integrated battery makes it easy to remove the battery for more convenient charging or travelling, and you do not have to worry about dropping it thanks to a secondary safety catch. You can also pair a 250Wh PowerMore range extender with your bike to chase your most epic adventures.

Bosch's Performance Line CX motor has 85Nm of torque out of the box but can be tuned up to 100Nm or 120Nm and 750W of power using the Bosch eBike Flow app. The all-new Bosch CX motor is lighter, quieter and more powerful than ever without wavering on natural-feeling support. The 800Wh battery provides enormous range, or you can swap to a 600Wh option for a lighter-weight ride with more nimble handling. Customise your ride with mudguards and a rack designed specifically for Powerfly, so you can customise your setup for everyday needs or epic exploration.
