The Powerfly is based on the concept of a trail bike with either 130 or 150 millimetres of suspension travel. The bike is based on this concept down to the last detail. For example, the battery has been moved down significantly compared to the previous year, resulting in a lower center of gravity. The sturdy Bontrager rims with 32 spokes and 27.5-inch diameter are fitted with 2.8-inch Schwalbe tires. The Fox forks are specified as 34 mm models, which provide extra stability especially for e-mountainbikes. And for the gears, the EX1 drivetrain from Sram is used - also an e-bike-specific accessory choice. And finally, the stoppers, where the four-piston Sram Guide brakes do their job - with metallic brake pads, of course. The 2018 Trek Powerfly may not seem like a major revolution. Nor is it, but rather an uncompromisingly well thought-out e-mountainbike - which is often not found to the same extent on comparable competitor products.

In the first ride test, the Trek Powerfly keeps its promises - a solid and versatile e-mountainbike. The new MTB mode from Bosch has already been implemented, making many things easier for the rider. The constant switching between the motor stages is actually superfluous. Switch on, ride off and concentrate on the tour. The Powerfly may not be the most agile of its kind, but it is very stable. The suspension kinematics, which are basically modeled on a Trek Remedy, are excellent - a safe bet for singletrack. The only thing that could be improved are the Nobby Nic tires from Schwalbe, which don't provide enough grip on the ground in the 2.8 version. However, Trek has announced that it will fit grippier tires on the final production bike.
