With the Powerfly FS 9 Equipped, Trek want to unite supposed opposites and send standard bike categories into a well-deserved retirement. With its great all-round qualities, the Powerfly FS 9 Equipped has already secured victory in last year’s trekking ebike group test. But what does Trek’s ebike do better than other e-trekking bikes?

Trek Powerfly FS 9 Equipped | Bosch Performance Line CX/625 Wh | 120/100 mm (f/r)
27.10 kg in size L | € 7,299 | Manufacturer’s website

The € 7,299 Trek Powerfly FS 9 unites supposed opposites and covers a wide range of applications. It’s equally suitable for commuting as for touring, both on and off road. Trek’s full-suspension ebike boasts a stylish aluminium frame, sporty silhouette and high-quality workmanship, all topped off with a flashy paint finish. The powerful Bosch Performance Line CX motor packs a punch in all situations, making it easy to negotiate steep ramps. This draws its power from a 625 Wh battery, which can be removed from the side of the down tube and carried to a charging point using a practical handle.

With the Powerfly FS, you can replace the linear Tour support mode with the progressive eMTB Lite mode, which is optimised to provide increased range but still churns out plenty of power when needed. In times when almost everyone has a smartphone on them at all times, the Bosch SmartphoneHub allows you to use yours as a display for your Powerfly FS. This enables many clever functions such as a navigation, music player and call management, which can be controlled remotely via a bar-mounted remote.

Behind the colour-matched cover hides a 625 Wh battery that can be removed from the side of the down tube.
On long tours, you can attach a smartphone to the spring clip on the SmartphoneHub and use it as a display. On shorter rides without a smartphone, the small display on the hub provides all important riding data.
Trek provided the Powerfly FS with powerful Shimano XT four piston mountain bike brakes – awesome!

While the pannier rack with 25 kg load rating and practical MIK adapter makes it easy to attach panniers to your Trek Powerfly FS 9, the low(ish) permissible total weight of 136 kg calls for prudence when packing. A Supernova MINI2 headlight and E3 tail light ensure excellent visibility. Not as excellent is the rest of the everyday equipment, including the short plastic mudguards and flimsy kickstand. The Trek delivers plenty of riding fun and intuitive handling on long tours and yet is easy to maneuver even in more demanding riding situations. The 2.4″ Bontrager LT4 Expert tires ensure good traction and comfort both on hardpack and loose terrain but tend to clog up easily in muddy conditions. Bigger impacts are taken care of by the sporty and efficient suspension, which controls 120/100 mm travel at the front and rear, respectively.
