Powerfly FS 7 Gen 2 - Trek Bikes (IE)

Overview

You want to boost your mountain biking capabilities with a high-end pedal-assist system. You plan to hit the trail often, and want an upgraded parts spec that'll help you push your limits.

A durable aluminium frame that fully encases a long-range 625 Wh battery, a powerful Bosch Performance CX (250 Wh, 85 Nm) motor that helps you sustain speeds of up to 25 km/h and a Kiox controller. Plus, a RockShox Gold RL 120 mm suspension fork, 100mm of rear travel with a RockShox SIDLuxe Select+ shock, powerful 4-piston hydraulic brakes, Bontrager Line Comp 30 wheels, a 12-speed Shimano drive train and a dropper post.

This full suspension e-MTB is a blast to ride. It has upgraded suspension, brakes, wheels and more that can help you reach new destinations on the trail.

For e-MTB, full suspension is a game-changer: it soaks up rugged terrain, so you can ride the Bosch pedal-assist system to its full potential
The dropper post lets you lower your saddle on the fly so it's out of the way on descents
Wide Line Comp 30 wheels provide more tyre support for better traction and control, and they come completely tubeless to save weight and prevent flats
The full-colour Kiox controller displays ride info, connects with your Bluetooth-enabled devices and has a built-in theft prevention feature
Trek's Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame for protection, makes it easy to remove the battery without tools and lets you mount a water bottle cage – even on full suspension e-MTBs

'The Powerfly FS blends sporty handling, efficient propulsion and long-distance comfort into a harmonious overall concept. The result: pure riding fun! '

'The jury was enthralled by the upright and comfortable riding position on long tours while the bike also shines on moderate terrain thanks to its fun ride and intuitive handling.'

Features

The Bosch Performance Line CX sets the standard for eMTB performance with up to 85 Nm of torque and an intelligent eMTB mode with Extended Boost that automatically adjusts the amount of assist based on the terrain.

Trek eMTBs feature a custom eMTB Lite mode in place of Tour mode. It gives you more natural-feeling power delivery and longer battery life.

RIB is a one-piece battery and cover with a built-in handle that can easily be removed and re-installed in the frame with no tools and no hassle. It’s the most convenient way to remove your battery for transport, security or just easier charging.

Bosch Kiox's bright, full-color screen is easy to read in any light conditions and is protected by durable Gorilla Glass. You can view battery life, support level, speed, heart rate, and more. Plus, it seamlessly connects to your phone through the Bosch eBikeConnect app to share ride data, GPS map routes, altitude, cadence, and power output.

The right wheel size paired with your frame size gives you the perfect combination of responsiveness and control.

Use the remote lever to lower your saddle so it's out of your way when you're descending and cornering.

You've got one less detail to sweat with the integrated speed sensor. The chainstay-mounted sensor stays protected while the custom hub-mounted magnet stays secure – no more error codes from mis-aligned sensors.

The bike is already internally wired to accept additional lights. Go to your dealer and simply have them attached to the bike and plug them in.
