Trek Powerfly FS 9 Equipped in review – A new generation of E-trekking bike

With the Powerfly FS 9 Equipped, Trek have developed a unique concept that looks beyond conventional bike concepts and combines the best features of different worlds instead. Was the Powerfly FS 9 Equipped able to assert itself against the competition in our E-trekking bike group test?

That eBike is part of our big trekking eBike group test . There you can find an overview of the test fleet and all information on the latest generation of trekking eBikes.

Trek Powerfly FS 9 Equipped in review – Is this what the next generation of trekking bikes feels like?

It’s all a matter of balance: with the Powerfly FS 9, Trek have made it their mission to blur the boundaries between bike categories and combine the best of the eMTB and E-trekking bike worlds. Instead of prioritising particular riding characteristics, Trek’s full-suspension ebike was developed to blend supposed opposites and create a balanced and harmonious riding experience, both on- and off-road. To find out whether the concept actually works, we tested the flagship Powerfly FS 9 Equipped, which weighs 27.10 kg and retails for € 6,999. The upright pedalling position allows you to concentrate on the trail ahead and is pleasantly balanced, distributing the weight evenly between the hands and saddle – the perfect prerequisites for a great tourer! At the same time, the balanced weight distribution ensures good control over the front wheel and generates lots of traction at the rear. The Bosch Performance Line CX motor delivers plenty of power in all situations and is easy to modulate thanks to the progressive eMTB mode. Moreover, the Trek has a second progressive mode called eMTB-Lite, which is optimised to provide increased range. The intuitive handling makes it easy to lean the bike into wide corners and take advantage of the wide handlebars to dodge potholes and obstacles with quick and controlled turns. Although it’s not as playful as a trail bike, the Powerfly is great fun and easy to control on easy trails, getting you to your destination quickly and safely even when the route includes unpaved trail sections on challenging terrain.

Specific Features

Supernova MINI 2/E3

Well-equipped for everyday life and excursions

The wide, high-volume 2.4” Bontrager LT4 Expert tires generate plenty of traction and feel predictable both on tarmac and loose terrain, inspiring huge amounts of confidence in all situations and only sliding out in muddy conditions. Shimano XT four-piston brakes with 200 mm rotors provide powerful and reliable deceleration. Even on long descents with a full pannier on the rack, they deliver consistent braking power and good modulation. While at 108 kg the Trek has a relatively low maximum payload, even with a 10 kg pannier on the rack it’s good natured and easy to manoeuvre, feeling significantly more composed than other bikes with a higher maximum payload ratings – i.e., the Kalkhoff Entice 5 Advanced+. The pannier rack features a practical MIK rail, which makes it easy to attach compatible bags and is approved for a 25 kg load. The Supernova MINI 2 headlight and E3 tail light look great and are powerful enough for night riding. Unfortunately, other accessories don’t live up to the otherwise high-quality spec of the Powerfly. The plastic mudguards are too short and can’t prevent mud from flying onto the person riding behind you and the kickstand makes a loud rattling noise.Trek-Powerfly-FS9-Equipped-Trekking-E-Bike-Test-Review-2021-mag-0007.jpg

Tuning tip: Bosch Help Connect plan with fall detection for solo adventurers

Stiff – Riding comfort onboard the Trek Powerfly FS 9 Equipped

The suspension of the Trek Powerfly FS 9 Equipped consists of a SR Suntour Zeron 35 fork and semi-integrated RockShox SID Lux Select+ shock, controlling 120 and 100 mm travel respectively. Although the numbers suggest a high level of comfort, the suspension is tuned for maximum efficiency which translates into a stiff and sporty rear end. On smooth tarmac, this converts each pedal stroke into efficient propulsion, without the rear end bobbing. Small bumps and vibrations are mostly dealt with by the high-volume tires while the suspension takes care of bigger hits, working actively and efficiently. As a result, the Trek is less comfortable than the Riese & Müller Homage but, in return, doesn’t feel as sluggish. The low-slung top tube and 150 mm Bontrager Line dropper post make it easy to get on and off the bike.

Propulsion first! The sporty suspension is tuned uncompromisingly for efficiency and riding fun, not for comfort.”

A smartphone as an on-board computer – The connectivity of the Trek Powerfly FS 9 Equipped in detail

One of the most striking equipment features of the Trek is the versatile Bosch SmartphoneHub. For short rides, this can be used without a smartphone. The basic 1.5” display shows all key data such as battery charge and speed. If you want other functions like navigation or fitness tracking, you can connect your phone to the SmartphoneHub via the COBI.Bike app and Bluetooth. While riding, the smartphone is firmly attached to a spring clip on the SmartphoneHub, where it can be operated via remote and charged via the hub itself. The COBI.Bike app offers a wide range of functions including voice navigation. If you tend to ride a lot on your own, you should take a closer look at Bosch’s Help Connect function (€ 4.99/month or € 39.99/year) with fall detection mode. This can notify your local emergency services in the event of a crash and is currently available in 11 European countries.

Quick off-road blast or long weekend ride? The Trek Powerfly FS 9 Equipped doesn’t say no to either!“

This is what the future of trekking looks like – The Trek Powerfly FS 9 Equipped in detail

Even whilst stationary, the Trek Powerfly FS 9 Equipped cuts a damn fine figure. Particularly striking are the sporty silhouette with its low-slung top tube and the elegant finish with its dark accents. Unfortunately, the chaotic cable management in the cockpit area spoils the otherwise tidy look. The Bosch Performance Line CX motor is neatly integrated into the frame and protected by a skid plate, while the 625 Wh battery is integrated into the down tube and can be easily removed to the side. The battery cover features Trek’s trademark carrying- handle while the battery cover and charge-port cover on the seat tube are both painted to match the colour of the frame. The charge port cover is easy to open and closes automatically – awesome! Not only the frame but also components like the handlebars, dropper post and BontragerLine Comp 30 wheelset, which Trek also use on their other performance-oriented eMTBs, make a great impression. In the smaller XS and S sizes, the Trek Powerfly comes with smaller 27.5″ wheels while all other sizes roll on big 29” wheels.

Trek Powerfly FS 9 Equipped conclusion

The Trek Powerfly FS 9 is exceptionally versatile and covers a wide range of applications, giving the concept of trekking a whole new meaning. The finely-tuned suspension and balanced pedalling position ensure sporty yet predictable handling and top riding fun while inspiring huge amounts of confidence on long off-road expeditions. The everyday equipment makes daily commutes and weekend trips more comfortable. The elegant look rounds off the successful concept of the Trek Powerfly FS 9, which comes out on top in our E-trekking bike group test, securing the coveted Best in Test.

About the author.

Rudolf Fischer

In his previous life Rudolf was a dab hand at promoting innovation, putting his brain behind big-ticket patent assessments that easily ran into six-or-seven-plus figures. These days, the self-confessed data nerd’s role as editor at DOWNTOWN and E-MOUNTAINBIKE is no less exciting. Given his specialism in connectivity, Rudolf’s often placed on the front line of future mobility conversations, but he’s also big into testing new bikes–both on the daily as a committed commuter and intensively for our group tests. The business economist graduate is as versatile as a Swiss penknife, and that’s no hyperbole. Away from two wheels, his background in parkour means he’s a master of front, side and backflips, plus he speaks German, English, French, Russian and a touch of Esperanto. Japanese remains woefully unmastered, despite his best home-learning attempts. Good to know: Rudolf’s sharp tongue has made him a figure of fear in the office, where he’s got a reputation for flexing a dry wittiness à la Ricky Gervais... interestingly, he's usually the one laughing hardest.

Table of contents, trek powerfly fs 9 equipped gen 2 review (2023).

The Powerfly FS range is Trek’s answer to the daily use all-rounder. It’s designed to be a capable bike, which is comfortable on the urban routes, while also a fun ride on the trails. Getting that mix right is a real balancing act for a manufacturer because something has to give if it’s to be adept in both areas.

The Powerfly FS 9 Equipped Gen 2 is the second-highest-spec bike in Trek’s range, so how does it cope in the mountains? And are there any limitations? We’ve put hours into the pedals on this Trek Powerfly FS 9, to get all the answers for you.

Our Verdict

A reliable bike to take on the daily commutes, but vastly overpriced compared with the competition.

The battery and motor pairing are areas to celebrate, offering great range and a strong amount of power to cart the bike’s heavy bulk around.

However, the manoeuvrability is poor and the bike isn’t suited to challenging, off-road terrain.

It’s too cumbersome; it doesn’t offer great handling, and the tyres just don’t have enough bite.

But it’s the price we can’t get over. It’s far more expensive than some strong competitors in the market.

• Range reliability
• Powerful motor
• Manoeuvrability
• Poor on technical terrain

Trek Powerfly FS 9 Equipped Gen 2

Price: $8,330

Weight/frame.

The Powerfly FS 9 Equipped Gen 2 has a heavy aluminium frame, which brings the sturdiness you need on a daily commute. It moves quickly when it picks up momentum, which is ideal when you’re on concrete cycle lanes, but it does come at a big cost.

It weighs in at a very heavy 27.05kg , which means it isn’t well-suited on twisty sections or for more challenging trail riding. It’s adept on forest paths and wide single-tracks, but the minute you throw in some more challenging terrain, it starts to feel like you’re trying to manoeuvre a tank.

Just how fast does the Trek Powerfly go with that weight, though? It can get up to 26km/h comfortably with the assist on, but faster with momentum.

It comes in five frame sizes, from XS up to XL, and has a few extra commuter friendly features, such as decent mudguard so you can keep your commuting clothes clean if you have an off-road section to tackle.

Plus it comes with a kick-stand, which is handy if you need to leave it outside a shop, especially considering its weight.

The Powerfly FS 9 Equipped Gen 2 comes with a sizable 625Wh Bosch PowerTube battery . The PowerTube is a strong selection by the folk at Trek, and gives you a decent range.

We found that we could push out around 90km on one charge, with around 1,000m of climbing, and still had a little bit left in the tank to go on the following day.

These are good numbers for a bike designed for daily use – the last thing you want is constant range anxiety with a bike you need to use on a daily basis.

The Powerfly FS 9 Equipped Gen 2 comes paired with the excellent Bosch Performance Line CX motor . We’re big fans of the Performance Line CX, which can push out up to 85Nm of torque.

It’s one of the best motors out on the market right now, offering intelligent power delivery, reliability and a very powerful kick.

It works smartly with the Bosch PowerTube battery to release the power conservatively and it helps add to that reliability with the range estimation.

Considering the heavy overall weight of the bike, you need a solid motor accompaniment to drag you up challenging climbs and the Performance Line CX is certainly armed for the task at hand.

You could be mistaken for thinking the bike is much lighter by the way it makes easy work of big inclines, particularly on the concrete or hard-packed terrain; it feels heavier-footed on bobbly ground, though.

Motor Display

The Powerfly FS 9 Equipped Gen 2’s display is another fantastic Bosch product. Not only does the motor itself bring reliability, but the display adds to that, offering many different customisable view options, depending on the demands of the day’s ride.

You can switch between four modes of assistance easily using the handlebar-mounted smart controller: Eco , Tour , e-MTB and Turbo . This offers you more than enough options to take on the type of terrain and routes that you’re likely to want to do on the bike.

You can also link all your data to your smartphone, with handy tools such as mapping data, RPM output, along with all the battery information you need to make sure you don’t run out on a ride.

The Bosch Performance Line CX motor and its display are spot-on products.

The Powerfly FS 9 Equipped Gen 2 comes with 120mm travel at the front and 100mm at the rear . It’s set up with SR Suntour Zeron 35, air-sprung forks and RockShox SID Lux Select+ rear shocks .

We mentioned limitations earlier and this is certainly one to note. That suspension setup isn’t made for wild trail riding or even moderate trail riding, to be honest, and it soon comes unstuck on anything more complex than a wide single-track or forest road.

It doesn’t take lumps and bumps well and although it offers a small slice of cushioning, it really isn’t designed for the mountains.

ℹ️ If you’re wanting an off-road-focused bike, this really isn’t the one for you. This offers aspects which can cope in the countryside, but it’s also designed for paved streets. That compromise means that it loses out in certain areas. Suspension is one.

If you’re just looking for some forest tracks or country paths, then this offers an adequate amount of travel to cope with those demands and you switch from road to off-road terrain feeling pretty comfortable. Comfort is what the bike is designed for, but within the parameters we mentioned above.

Wheels/Tyres

The wheel size on the Powerfly FS 9 Equipped Gen 2 depends on the frame size you go for. The XS and S frame sizes come with 27.5in wheels , whilst the larger models come with 29in wheels – both a Bontrager alloy setup, with Bontrager LT4 Expert tyres .

The alloy wheels add to that stability you feel while riding the bike – they’re robust and give you a strong planted feel out on a ride. However, they are heavy and they contribute to the overall heavy bike weight.

The tyres offer you enough bite to cope with a slice of countryside, but also enough shedding ability so they can move quickly on the concrete, too – it’s another balancing act from Trek to be able to straddle both the off-road and on-road worlds, however, it comes at a cost.

ℹ️ The tyres don’t offer enough bite to be flying into technical corners or anything too steep, off-road. With the heavy weight of the bike, you could find yourself on the deck if you tried to push the bike in those settings.

The Powerfly FS 9 Equipped Gen 2 comes with Shimano XT M8120 4-piston brakes . They’re a powerful setup, and do offer a strong bite to contend with that weight and the chunky motor.

We felt like they adequately coped with the job in hand and never gave you any cause for concern – a relief considering the tyre issues

This Powerfly FS Equipped is fitted with a Shimano XT M8100 12-speed drivetrain . A very reliable partnering, a bit like the motor and battery – offering smooth shifting and an ease of use.

The price is upsetting considering the bike’s limitations in quite a few areas. However, a decent chunk of that price is going towards the Bosch motor and battery, which are both extremely reliable and very good products to have at your disposal.

That eases the pain to a degree, but we still think it’s vastly overpriced for what you’re getting.

How Does it Compare?

There aren’t a huge number of manufacturers targeting this area because of the compromises you have to make to try and make the bikes work well in both commuting and trail environments.

However, Canyon has tried to step-up to the mark with its Pathlite: ON 5 SUV , so how does it stack up to our Powerfly FS 9 Equipped Gen 2.

It comes with exactly the same battery and motor pairing, the 625Wh Bosch PowerTube battery and the Performance Line CX motor.

It also comes in slightly under the weight of our Trek, but only marginally at 26.86kg, due to its aluminium frame.

It has 100mm of travel at either end with a similar Suntour forks set-up and comes with 27.5 inch wheels, with Maxxis Crossmark II tyres, which offer a decent bite.

It’s a very similar bike to our Trek, which has the same sort of limitations – good on hard-packed and simple trails, but comes unstuck on anything more technical.

That said, Canyon has managed to keep the price down at $3,605 – nearly $5,000 cheaper than our Trek Powerfly FS 9 Equipped.

It really makes you wonder how Trek are trying to justify that huge difference, considering that the bikes really are very similar.

Final Thoughts

It’s a very overpriced bike, but it does the job it intends to – helping to bridge the gap between the daily commute, with a bit of trail riding.

It certainly has limitations, though.

It isn’t meant for any real degree of serious trail riding and it would come seriously unstuck on anything technical or particularly challenging.

However, it offers a comfortable ride experience for the daily commutes, on simple single-tracks and on forest roads.

It has a top battery and motor pairing, which bring great reliability, a chunky amount of range and a powerful kick to heave its heavy weight around.

We’re pained by the price, though. We just can’t understand the justification for the high price, particularly when you compare it to some competitors operating in this same sphere of the e-MTB world.

There are definitely pros and cons with this one, but it does the job the bike is designed for – reliability being a key theme. If that’s what you’re looking for, then get out there and give it a whirl.

Trek Powerfly FS 9 Equipped

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?

For an overview of the test fleet head to the group test: 9 fully equipped ebikes for trekking and adventure in our test

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.

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.
