Trek Powerfly FS+ 4 Equipped 800Wh Gen 4 2026 electric bike image 01

Overview

The Trek Powerfly FS+ 4 is a capable mountain e-bike built for trail riding, offering strong motor support and a high-capacity battery that provides reliable range for most adventures. Its hydraulic disc brakes deliver confident stopping power, and the removable battery adds convenience for charging and storage. However, the bike's charging time is notably slow, and while the motor is powerful, it may feel less punchy in acceleration compared to some competitors. At 27.41 kg, it's heavier than average, which might make lifting it more challenging, especially when transporting or storing.
