Trek Powerfly 4 625Wh Gen 4 Review

Bosch is the major motor manufacturer in the EMTB world, alongside Shimano - and it's no surprise, as the Performance Line CX Smart System shows. The very well-rounded motor control and the dynamic power output characterise the character of the Bosch motor. The well-tuned riding modes cater to bikers of all preferences. The very well-rounded motor control and the dynamic power output characterise the character of the Bosch motor. The well-tuned riding modes cater to bikers of all preferences. Thanks to the good range, longer tours with the Powerfly 4 are no problem.

On rough terrain, the Powerfly 4, with its only average fork, lacks some control. In descending situations, the Tektro brakes require a lot of hand strength or, optionally, courage from the rider. With two pistons, they only brake poorly. At the drivetrain components and the rest of the parts, Trek uses average parts. When it comes to the geometry, Trek does not go completely crazy. The head tube angle and reach values were chosen with care. The result: A balanced riding behaviour with a good combination of playfulness and straight-line stability.
