Trek Powerfly FS+ 4 Gen 4 2026 electric bike image 01

Overview

The Trek Powerfly FS+ 4 Gen 4 is a capable mountain bike designed for trail riding and off-road adventures, offering smooth motor support and confident braking for varied terrain. Its front and rear suspension provide good comfort on rough roads, while the removable battery adds convenience for charging and storage. However, the bike's charging time is notably slow, and its battery efficiency means you may need to plan more carefully for longer rides. Weighing in at over 24 kg, it's not the easiest to lift, but its strong motor and hydraulic brakes make it a solid choice for serious trail riders.
