Trek Powerfly FS 9 LT 2018 Electric Mountain Bike

As demand for pedal-assist mountain bikes continues to surge, Powerfly stays ahead of the competition with a performance-packed lineup that integrates Bosch’s industry-leading pedal-assist power with Trek’s proven mountain bike technology. The lineup still includes the 130mm Powerfly FS (Full Suspension) and the 150mm Powerfly LT (Long Travel, as well as a full line of hardtails, including Women’s models.

Bosch’s off-road Performance CX system returns with the battery now integrated into the downtube. Integrating the battery isn’t just about the clean, cool looks. With the weight of the battery resting lower in the frame, integration provides better ride quality. Additional upgrades to all models include the low-profile Purion display, a new intuitive e-MTB ride mode, and long-life 500Wh battery.

These updates include Powerfly 4, which uses a carry-forward frame to offer pedal-assist with excellent value. The new hardtails also get Boost hub spacing for increased tire clearance, and even the ability to accommodate plus-sized tires, which come stock on the 9 model. All of the 9-level Powerfly models get maximum electric-assist performance with an optimized e-MTB spec package that includes SRAM’s e-bike specific eX1 drivetrain, Guide RE brakes, and Fox’s e-optimized Float forks. Of course, the full-suspension models feature the Trek technologies that make for the best-handling bikes around, including ABP, EVO Link, and Straight Shot downtube. Both Powerfly LT models also get our exclusive RE:aktiv shock for additional responsiveness and control over more demanding terrain.

The fascination of eMountain biking

Pure riding enjoyment in every situation – whether uphill or downhill. This takes eMountain biking to a new level. The perfectly delivered power of the Performance Line CX motor and the new eMTB mode introduces a completely new riding sensation.

Key Bosch features on the 2018 Trek Powerfly FS 9 LT:

Bosch Performance CX

Bosch’s Performance CX line is made for rugged off-road use with a maximum torque of up to 75 newton meters, sustained into the high cadence range for sporty acceleration and a sleek mid-mount motor for ideal weight balance and obstacle clearance

With a maximum torque of 75 Nm, the Performance Line CX is the ideal drive for ambitious and demanding eBikers. In eMTB mode, you always receive the required power – from Tour to Turbo. Up to 300% of perfectly delivered support, incredible dynamism and unique grip provide the best possible support on all terrains, as well as improved start-up behaviour. The progressive motor support automatically adapts to the individual’s riding style, so there is no need to change support modes in eMTB mode.

The highlights

Direct flow

Perfect support as soon as you step onto the pedals means that starting on steep slopes is significantly easier.

No trigger

Thanks to the new eMTB mode, there is no need to change support modes, so the rider can concentrate fully on the trail.

Trail Control

Enables effortless riding and optimal traction thanks to improved control, even on challenging uphill sections or when encountering difficult obstacles.

Maximum momentum

A torque of up to 75 Nm ensures sporty acceleration even in alpine terrain, without changing gear.

More walk-assistance power

Stronger support up to speeds of 6 km/h makes pushing your bike much easier. Available from autumn 2017 and backwards compatible for all Performance Line CX systems.

eMTB mode

For a powerful start uphill and in rough terrain. Improved moving-off behaviour guarantees optimal support in all terrains and on any trail. Noticeably easier, sporty starting as soon as you step onto the pedals.

Bosch Power Pack 500

The premium Bosch lithium-ion battery features 500WH and a guaranteed long lifespan. The battery not only ensure long distances, but is also easy to remove and take with you.

The Bosch PowerPack 500 is the same size as and only slightly heavier than the PowerPack 400 but extends the range. The Lithium-ion battery requires about two hours to charge 50% and the PowerPack 500 takes approx. 4.5 hours to charge with the Bosch Standard Charger. In favourable conditions, charged and with the Performance Line Cruise in the mix, tours of up to 90 kilometres are possible. The PowerPack 500 is available for all product lines as a frame or rack battery.

Bosch Purion Display

Bosch’s Purion display features a fully-functional speedometer with a backlit display, service interval indicator and battery range indicator. It’s thoughtful design allows riders to scroll through functions or choose the right level of support while maintaining contact with the handlebars

The highlights:

Clear display-

Charging status, speed, riding mode, range, trip distance, total distance

Optimum legibility-

The display without play lighted from behind enables recognising all riding data.


The optional service interval display reminds you about fixing the next service appointment for your eBike with the specialist dealer.

Easy diagnosis-

The specialist dealer can monitor the status of your Bosch eBike System via the micro USB interface.

Focus on the essentials-

Five support steps, safe operation with thumbs, neat handle bar.


No support, Purion continues to provide all important information.


Effective, but gentle support, designed for maximum efficiency for long ranges.


Uniform support for long stretches, with clear focus on long ranges.


Immediate, powerful support for sports riding on natural terrain and even in city traffic.


Direct and maximum powerful support up to the highest pedalling rates for sports riding.

*The eMTB mode, specially designed for the Performance Line CX, dynamically varies between the Tour and Turbo riding modes, progressive motor support for maximum performance on the trail.

Key features on the 2018 Trek Powerfly FS 9 LT over other brands on the market:

Alpha Platinum Aluminium

Our premium lightweight aluminium is continuously cold extruded and butted at multiple points, and hydroformed into sophisticated tube shapes for maximum strenght and minimum weight

Motor Armour

This unique protection shield made of lightweight yet robust aluminium protects the motor against stones


Wider dropouts (110mm front, 148mm rear) gives you the stiffness of a 27.5″ wheel with all the benefits of a 29″ wheel, and Boost 148 at the back lets you run wider tyres and a larger chain ring without affecting Q-Factor and pedaling efficiency

Straight Shot with Knock Block

Trek’s all new Straight Shot frame design featuring Knock Block frame defence optimises stiffness-to-weight ratio for a more responsive ride

ABP (Active Braking Pivot)

Our patented Active Braking Pivot allows your suspension to work freely whether you’re on the brakes or off. It’s smooth, controlled suspension that’s at its best all the time

G2 Geometry

Advance frame geometry and a custom offset fork give our 29ers (and plus) precise handling at low speed without compromising high-speed stability. We call it G2 Geometry and it’s why our 29ers (and plus) handle better than anyone else’s


RE:aktiv brings Formula 1 technology to mountain bike suspension. A Trek Exclusive.

Better flow, better ride:

Any mountain biker understands the bliss that comes with zeroing in on the trail and nothing else. No outside distractions—including inconsistent suspension performance. That’s what it’s all about. More flow is RE:aktiv’s greatest gift.

You’ll accelerate as aggressively as you can without losing efficiency to pedal bob. You’ll confidently take gnarly, technical lines knowing that your rear shock will provide an instant, supple response. You’ll feel the difference of a shock that immediately transitions from soft to firm as you fly out of corners. You’ll experience the beauty of simply being in the moment.

RE:aktiv does exactly what you need it to do, exactly when you need it to. No more adjustments on the trail, no more choice between efficiency or control—pure confidence and enjoyment no matter what the trail brings you.

Set and forget:

RE:aktiv was designed to complement existing suspension settings, such as climb and trail modes. RE:aktiv can function effectively in all three settings, allowing you to simply pick the proper setting and let her rip. Wouldn’t it be nice to no longer interrupt your flow to flip between suspension settings during a ride? It simply makes the shock better all the time.
