Trek Powerfly+ 4 800 Wh Gen 5 E-Mountain Bike in Gloss Dark Star/Matte Dark Web

Season:2026

Brand:Trek

Code:61707BLK

The Trek Powerfly+ 4 800 Wh is an adventure-ready electric mountain bike featuring a rugged aluminium frame and a powerful Bosch Performance Line CX motor.

This bike provides a full-assist ride that is both versatile and powerful. The Bosch Performance Line CX motor delivers plenty of torque for steep, punchy climbs and is easy to control with the Purion 200 remote. You can customise the motor settings in the eBike Flow app. The motor has 85 Nm of torque out of the box but can be tuned 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 more powerful than ever, offering natural-feeling support for crushing epic rides.

The massive 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. The RIB 2.0 Removable Integrated Battery makes it easy to remove the battery for more convenient charging or travelling, and a secondary safety catch prevents accidental drops. The bike is compatible with Bosch PowerMore booster batteries for extending your ride even further, allowing you to pair a 250 Wh PowerMore range extender.

A bump-smoothing SR Suntour suspension fork boosts confidence on any trail. The 10-speed Shimano CUES provides clean shifting. The 2-in-1 remote and display provides all the information and control you will need in a compact, full-colour handlebar controller with intuitive controls. The Bosch Purion display features a fully-functional speedometer with a backlit display, service interval indicator, and battery range indicator. Its thoughtful design allows riders to scroll through functions or choose the right level of support while maintaining contact with the handlebars.
