New Trek Powerfly FS 2021 – introducing Trek’s brand new tour-oriented allrounder with the new Bosch Performance CX motor

Trek have just released their Powerfly FS, a brand-new bike aimed at eBikers with a penchant for touring. With a 4th-generation Bosch Performance Line CX motor and 120/100 mm travel (f/r), the Powerfly FS was designed to suit a wide range of applications, from daily commutes to epic trail adventurers.

The Trek Powerfly has been an integral part of Trek’s eBike portfolio for several years now. The LT version (Long Travel) was replaced last year with the new Trek Rail, which already came with a 4th generation Bosch Performance Line CX motor. Tour-oriented eBikers, however, had to make due with the outdated FS version, which had 130 mm of travel and, unfortunately, still the old Bosch motor. With the new Powerfly FS 202, Trek are addressing the touring segment more specifically, while maintaining the Rail model as part of their trail-bike segment. The new Trek Powerfly FS 2021 starts at € 3,898 and is now available from your trusted Trek dealer.

New motor in a new frame

Hardcore Trek fans have a reason to celebrate. Finally, the Powerfly FS, which still had an old Bosch motor last year, is available with the latest 4th generation Performance CX drive. To make it compatible with the new motor, Trek redesigned the frame platform of the Powerfly FS 2021 from scratch. The engineers moved the shock behind the seat tube and adjusted the travel of the whole bike, with 120 mm at the front and 100 mm out back. The fully integrated 625Wh battery slides out of the frame sideways, without the need of tools. As its predecessor, the battery can be charged both on and off the bike and features a very clever carrying handle on the top of the housing.

On the new Trek Powerfly FS, the shock sits behind the seat tube.

From trail adventurers to everyday commuters – all spec options in detail

As mentioned before, the Powerfly FS 2021 was designed to be the true all-rounder in Trek’s eBike portfolio, which explains the five different spec options. Alongside three traditional, trail-compatible models, there are two more models, which go under the name of ‘Equipped’ and were designed to suit the needs of tourers and commuters alike. They come with a front and rear mudguard, a powerful lighting system, a kickstand and a pannier rack as standard. While the Trek Powerfly FS 4 features a Bosch Purion on-board computer, all high-spec models come with a Bosch-Kiox display or Bosch SmartphoneHub. As you’d expect from Trek, all models are available in a wide range of colours.

The Trek Powerfly FS ‘Equipped’ is set to become the new all-rounder in Trek’s eBike portfolio

The geometry in detail

To cover the widest possible range of applications, Trek release the Powerfly FS in 5 different spec options and just as many frame sizes – XS to XL. While the smaller XS and S sizes come with 27.5″ wheels , all other sizes feature 29″ wheels. A quick glance at the geo tab suggests an upright and thus comfortable riding position, which offers the ideal conditions for long rides – the high front-end and the slack seat angle are mainly responsible for this.
