Trek Powerfly FS 9 EQ Electric Mountain Bike
Perfect for rugged commutes and weekend single track missions, the Trek Powerfly FS 9 EQ Electric Mountain Bike is a versatile quiver-killer with utility-focused features. This all-road package excels at city, path and singletrack use, ideal for transitioning from the office to the trail. 100mm of rear suspension and 29" wheels provide excellent grip and optimal comfort no matter the terrain, and a top-tier component specification provides an excellent ride quality. Featuring Bosch’s critically acclaimed Performance CX motor, the Powerfly FS offers more than enough power for even the toughest climbs.
For day-to-day ease of use, this Equipped version is pre-fitted with a range of utility orientated features. Mudguards offer puddle and spray protection, ideal for keeping your work clothes dry on mixed terrain rides. The rear pannier is ideal for transporting luggage, while a bike stand is convenient for storage. To increase low-light visibility, bright front and rear LED lights are fitted. These draw their power from the bike's battery, ensuring a simple single charge solution for all the bike's power needs.
Bosch’s Performance CX motor system offers 75Nm of torque for an unstoppable ride experience. The 625wh Bosch PowerTube battery keeps you riding free from range anxiety, with its high capacity tackling even the longest loops with ease. Seamless integration provides clean lines, with the integrated battery being removable for off-bike charging if required. The Bosch SmartphoneHub allows you to stay connected to the bike, allowing for easy navigation and displaying important ride-data.
With a well thought out selection of quality components, the Powerfully FS 9 EQ offers a premium electric bike experience on all terrain. The 12-speed Shimano XT drivetrain and four-piston XT brakes provide a slick-shifting experience, backed up with powerful braking to accommodate the added weight of motor and battery. A RockShox 35 Gold RL fork features a trail-taming 120mm of travel, while the SIDLuxe Select+ rear shock irons out bumps, ruts and potholes.
