Trek Powerfly 2019 Review – now with a carbon frame and fully-integrated battery

The Trek Powerfly has become a true eMTB classic and has undergone several updates over the years. To keep up with the competition for the new season Trek equipped the latest version of their popular bike with an integrated battery and also introduced two fine carbon versions of the Powerfly LT. Here you’ll find all the details!

A few years back Trek did a great job and gave the Powerfly a well thought-out and very well balanced geometry — which once again fully convinced us in our latest test . Sure there are more nimble bikes on the market but the new Powerfly strikes a great balance between uphill and downhill performance. For the new season Trek sticks to the proven geometry and rear-end of the previous version but ads a fully integrated, removable battery. On top of this the new model is available in two carbon versions and the spec has been optimised too. All Plus models are now rolling on sturdy, grippy Bontrager XR4 tires and all Powerfly LT models feature powerful four-piston brakes.

Here are the highlights of the 2018 Powerfly line up at a glance:

– New fully integrated, removable battery – Two Powerfly LT carbon models – eMTB-specific fork on all Powerfly LT models – Four-piston brakes on all LT models – Bontrager XR4 tires on all Plus models – More colour options – SRAM Eagle groupset on some models – Robust RockShox Revelation on the Powerfly FS7 model – Updated Bontrager Line dropper – Powerfly Sport-Hardtail with lights and mudguards

 Trek RIB: probably the best fully-integrated and removable battery on the market

There is a vast choice of eMTBs with integrated battery on the market but only a few systems are thoroughly thought-out and refined down to the last detail. Some bikes come with super long batteries, on others the battery can’t be locked and can only be removed with the help of tools. And then there are systems made up of several parts (battery and cover). A battery can weigh up to 4 kg so when you remove it you have to be really careful not to drop it on the floor and break it.

You can tell that the engineers at Trek gave the development of the RIB system (removable integrated battery) a lot of thought. The battery and the cover are one solid unit and the 500 Wh Bosch Powertube battery can be removed to the right hand-side. The system makes sense as most of us tend to lay their bike on its left side to avoid damage to the rear derailleur. Once you released the battery with the key it will pop out by a few centimetres; after depressing the big button you can remove the battery completely. An integrated handle makes the whole procedure easier – what an ingenious system! In addition the new integration allows you to place a bottle cage and a large drinking bottle in the main frame triangle.

The new carbon frame allows for less weight and sleeker integration

The new carbon frame proves just how much Trek believed in the geometry of the previous Powerfly LT model. The Americans could have revised the geometry for the latest update of the Powerfly but decided to stick to the familiar and very popular concept instead. Therefore the main advantages of the new carbon frame are a weight reduction of around 650 g and the significantly sleeker integration and appearance of the bike. Trek has equipped the top tube with a mounting option for a Wolftooth B-RAD system. The system allows you to quickly attach either an inner-tube or a tool to the bike and forget about carrying uncomfortable backpacks on short rides. In typical Trek style all Powerfly models come with a RE:aktiv rear-shock and ABP-link which keeps the suspension fully active even under braking. The geometry can be adjusted between two positions via a flip chip.

Revised spec for the Trek Powerfly LT Alu

Even if you won’t buy one of the carbon versions with the Powerfly LT you’ll get quite a few performance upgrades in the coming season. In addition to the battery integration Trek has adapted the spec of the bikes. All Powerfly LT models feature an eBike-specific fork and powerful four-piston brakes. Trek also redesigned the Bontrager Line dropper seat post and used the new SRAM Eagle groupset. Compared to the cheaper Schwalbe Nobby Nic Performance tires the new Bontrager XR4 offer noticeably more grip and puncture protection.

The Trek Powerfly LT 2018 on the Trail

We had the opportunity to test the Powerfly LT 9 at Trek’s launch-event on the gorgeous and varied trails in the Swiss Heidi-Land. Compared to the previous model the handling of the new version has changed very little. The better grip of the new tires might be the most noticeable change on the new version of the Powerfly. Like its predecessor the new Powerfly is a confident climber. The steep seat angle and rather long chainstays will get you at the top of steep climbs without a problem.

On the downhill the Powerfly feels safe and balanced. It’s not the nimblest bike out there but it’s still very easy to ride. You won’t have to shift your body weight too much to get good grip on both wheels and the bike will always feel pleasantly predictable. But if you’re looking for a very lively super nimble bike the Powerfly might not be able to fully satisfy you. Quick direction changes and narrow sections require a very proactive riding style and quite a lot of strength.

Our take on the new Trek Powerfly LT

Good stuff made better! Trek didn’t reinvent the wheel but the new Powerfly is a better version of the popular bike with many added improvements. The handling is very similar to the previous version. However you can clearly feel the performance upgrade of the tires. Unfortunately we didn’t get the chance to ride the new carbon version yet but even just the look of it has already convinced us. We’re not sure whether the carbon upgrade is worth the extra money but since our purchasing decisions are often driven by aesthetics and emotions we think that the new Powerfly Carbon will have certainly find many fans.

Beefed up the parts to deal with the beatings that e-bikes get

Product Overview

Trek powerfly 9 lt.

• Suspension, brakes and tyres are all on point. New battery layout is neat and easy to use.
• Could have more generous reach measurements and shorter stems on all sizes.

Manufacturer:

Price as reviewed:.

Up hill or down, ebikes take an absolute beating, so the new Trek Powerfly 9 has a beefed up the parts package to handle the additional abuse.

>>> The best electric mountain bikes

Trek Powerfly 9 LT need to know

• Integrated side-loading battery pack offers a sleek functional design
• Trek’s ABP suspension pumps put 150mm travel, coupled with a 160mm Fox 36 fork
• Bosch Performance CX motor and 500Wh battery packs on all models
• Two new carbon version shares the same geometry and sizing as the alloy Powerfly LTs

Forget torque, watts and even mismatched wheel sizes … integration is the real buzzword in ebike tech right now. And unless you go it alone with a custom motor like Rocky Mountain, something very few brands are prepared to risk, integration is currently about concealing the power-source.

150mm travel offers adequate cushioning while crushing the descents

Now in its third generation the new Trek Powerfly LT 9 has one of the neatest battery concealing solutions we’ve seen to date. Not only is its drive-side loading internal battery a breeze to use, it means the down tube on the latest Powerfly LT doesn’t need to be disproportionally large to contain the battery, like say, the Shimano equipped BMC Trailfox AMP .

Bosch PowerTube battery can be charged on or off the bike

Dubbed RIB, short for removable integrated battery, and with the protective cover positioned to one side the battery collects way less dirt too, so you’ll get way less grief for plugging the battery in next to the kettle for a quick charge. It even has a handy integrated carry handle for lugging it around. Best of all, RIB leaves plenty of space for a bottle cage, something that wasn’t possible with the battery position on the previous Powerfly LT.

Purion display is Bosch’s most compact

In keeping with the pack-less riding experience, tabs under the top tube also let you attach a custom Wolf Tooth B-Rad storage strap so you can have a tube and CO2 canister with you at all times.

Other than the new downtube that houses the RIB battery, and the addition of the storage tabs under the top tube, the 2019 Powerfly LT 9 shares the same travel, geometry and attitude as the bike that won our e-bike test last year. Numbers that include a slack 66deg head angle (high setting) for increased steering stability and a generous size range that stretches from 15.5in all the way to 21.5in. Times are changing fast in the world of e-bikes though, and the reach numbers on the Trek look dated next to the Vitus E-Sommet that won our recent Enduro E-bike test.

The Powerfly LT 9 also has relatively long chain stays, 474mm to be precise. And while these aren’t really on trend and may even upset the balance of the bike on the smaller frame sizes, they are a godsend for taller riders on the 19.5in and 21.5in bikes as they help load the front end on flat corners to stop it lifting on the steepest climbs.

And boy did we ride some steep climbs on the launch of the Powerfly LT 9 in Bad Ragaz, Switzerland, terrain that an elite level XC racer on a sub 20lb hardtail would struggle to conquer. On the Powerfly LT 9 however we winched our way up huge mountains with the assistance of the Bosch CX motor driving the new SRAM NX Eagle 11-50t cassette. Stay seated and the Trek offers seamless power delivery, especially in E-MTB mode that automatically toggles between Turbo, Sport and Tour modes to match your effort. Out of the saddle however the Trek has more pedal induced bob than e-bikes like the Vitus and Canyon equipped with full size chainrings rather than a tiny 15t driver cog.

It was on the descents however that the Powerfly LT 9 showed its true colours. Planted and sure footed, it gives you the confidence to release your grip on the powerful 4-pistion Shimano XT brakes and push the reinforced 2.8in Bontrager XR4 tyres to their very limit. With gravity working its magic the new Trek Powerfly LT 9 is an absolute riot, but at £5,200 it’s an expensive way to get your kicks when the Vitus costs £3,599.99

New 2019 Trek Powerfly – First Impressions.

The not-so-minor details.

2019 Trek Powerfly

Trek Bicycles

4499 - 8499

Aesthetically clean. Bosch e-MTB mode for a natural feel. Considered spec.

Long chainstays.

The bike industry is in full e-swing, with new e-bikes releasing faster than iPhones or GoPros. While Trek might have been a little late to the party – with their first pedal assist mountain bike released just in 2016 – their new 2019 models, however, send a strong message. A lot of resources have been thrown behind their electric bike program, and it certainly will pay off, the new Powerfly is a very well considered package.

Hear our first impressions in the video below.

What’s new?

• Three models available with the addition of a new LT (long travel dual suspension model) with 160mm travel forks, 150mm travel in the rear.
• A new OCLV carbon frame version of the Powerfly LT (ooooh yeah!).
• All three models; hardtail, FS, LT use a new fully integrated Bosch battery inside the downtube.
• New Bosch e-MTB mode equipped.
• E-bike specific forks, more robust and tuned specifically.
• Four-piston brakes on all LT models, and sintered brake pads across the range.
• SRAM Eagle on higher models with the new steel Eagle NX cassette.
• 2.8″ Bontrager XR4 tyres with reinforced sidewalls.
• The integrated battery allows for water bottle and tool storage mounts.
• New and improved Bontrager Line dropper post.
• Same frame geometry as 2018 FS and hardtail models.

Long travel Powerfly, where have you been all this time?

Previously only available from select overseas markets, the LT is finally coming Down Under. The Powerfly we reviewed last year was the FS model, with 130mm travel front and back. Certainly a great bike, but it didn’t take much for it to feel a little under-gunned when we took it to more technical trails or descents.

It’s as if the venerable Trek Slash got struck by lightning, or fell into the cauldron of magic potion, this is a long travel bike with superpowers! The suspension felt like what we’d expect from Trek; balanced, consistent and well suited to the cause.

We spent a big day riding big mountains on the Powerfly LT 7 Plus – a non-Australian spec model – we will see two models of the LT, the LT 9 and carbon LT 9.7 pictured below.

It’s as if the venerable Trek Slash got struck by lightning, or fell into the cauldron of magic potion, this is a long travel bike with superpowers!

A long travel model, however, is just the ticket to unlocking the Powefly’s true potential. We often don’t see the point in an e-MTB with less than 150mm of travel, with so much power at your disposal, lugging a larger bike around is no big deal. When you need a little more cushion for the push’n, a 160mm travel fork is just what you need to let the brakes off and push it.

Bosch’s new e-MTB mode.

While it’s simply just a mode setting, it makes the world of difference to how the bike rides. Selecting e-MTB mode on the display unit is like putting your camera into auto-mode, no, much better than that.

The whole idea of the e-MTB mode is to naturalise the feeling of power delivery, so the response feels much more like a normal mountain bike under pedalling forces – it delivers a less aggressive power output if you’re pedalling slowly and gently, ramping up the juice when you’re hammering at the pedals.

Read more about Bosch’s e-MTB mode and how it works here: Bosch e-MTB mode explained.

We tried riding in the three other modes – Eco, Tour, Turbo – and kept returning to e-MTB, it’s ideal.

Same geometry as 2018 models.

While it wasn’t music to our ears, news that the Powerfly’s frame geometry remained the same as last year, we do agree that Trek has made their decision after much consideration.

When reviewing the Powerfly FS 7 last year, we had criticisms of the long chainstays making it harder to muscle what are already heavy bikes around on the trails. At 475mm it’s one of the longest out there, what does that mean?

See our review of the 2018 model Powerfly FS here.

Well, with so much bike behind you, lifting the front end up by the bars requires a whole lot of effort, and on the trails that translates to a bike that you become a bit of a passenger on, steering it through the trails rather than hopping or manualling around. We’ve ridden plenty of e-bikes with shorter stays and despite the inherent weight of a motorised bike, you can still ride them like a regular bike.

On the flipside, a longer rear centre makes the Powerfly the best climbing e-bike we’ve ridden, hands down. Even with a tall 160mm fork, we took it up the nastiest inclines on the slipperiest surface with very little effort, the front end never lifted or wandered side to side. Their climbing manners are first rate.

Their climbing manners are first rate.

Climbs vs descents, stability vs agility, Toyota Landcruiser Troopy vs Suzuki Vitari? Everybody is different, we understand that. Though a middle-ground to build a more agile bike even at the sacrifice of climbing ability would be our preference.

E-Bike spec in the bag.

With the component manufactures sorting out their end of the deal and producing more parts that meet the demands of e-bikes, Trek has more to choose from. The 2019 range will have more four-piston brakes specced, tougher tyres, steel Eagle NX 12-speed cassettes and more robust forks that are tuned specifically for the heavier bikes.

Final thoughts.

While our opinions on the frame geometry remain, we appreciate that we might approach e-bikes different to others. The new bikes are very dialled, the new integrated battery will fool anyone from afar thinking it’s a regular bike, it is so aesthetically clean. And the addition of Bosch’s e-MTB mode is really clever, the bike rides very naturally.

We’re hoping to score a ride on the Powerfly 9.7 LT, to see how the OCLV carbon frame changes things, so keep your eyes out for more.

Trek Powerfly LT 9 first ride review

Trek's longer travel e-MTB has been updated

Sterling Lawrence / Trek

Trek’s e-MTB Powerfly line-up is rather large, covering hardtails, women’s bikes, 130mm full suspension models and even one that looks great for commuting. But it’s the 150/160mm LT versions that interest us most — after all, bigger is better.

Trek is adding OCLV carbon models to the LT range of bikes this year, but the LT 9 looks to be one of the choice models in the range.

• Trek add carbon and better integration with the new Powerfly range
• Why you should care about e-bikes

The Trek Powerfly LT 9 is its top-level longer travel e-MTB

Trek powerfly lt 9 frame.

The frame features Trek's new side-loading integrated battery (RIB), which pops out of the driveside of the down tube. The company believes riders tend to lean their bike on the floor on the non-driveside when they take the battery out of the bike, so this makes life more simple.

The battery also has a flip-out handle to make it easier to carry around, plus removal of the battery is tool-free.

The frame’s geometry includes a long 475mm chainstay. This, Trek says, is to aid technical climbing, because the front wheel is less prone to lifting. At the front, the 19.5in size (effectively Large) comes with a 448mm reach in the bike’s low setting (I generally never bother with a high setting anyway).

This is fairly short for the size of the bike, but still gives a 1,251mm wheelbase, which is on the long side. The head angle is a slackish 65.5 degrees and the effective seat angle is also slack at 73 degrees. The bottom bracket sits at a height of 344mm.

Trek uses its ABP suspension linkage on the Powerfly LT. The rear pivot is concentric to the rear axle, and there’s a rocker link driving the shock, which sits fixed at its other end to the frame (as opposed to it being a full-floater design as found on some other Trek bikes).

There are some nice design touches on the frame. The Knock Block system prevents the bars spinning too much in a crash, removing the potential for the fork crown to hit the down tube — this allows Trek to keep the down tube straight from the head tube to the bottom bracket, which should be lighter and stiffer.

There are also little rubber bump stops on the downtube, but personally I find the Knock Block system a little annoying when turning the bars for storage.

There’s room for a bottle cage, and the internal cable routing is neat. There’s a rubberised chainstay protector on the drive side, and even a kickstand mount on the non-drive. Trek has also updated the Powerfly LT to be able to accept 2.8in tyres.

Trek Powerfly LT 9 kit

This is the highest tier alloy LT and the kit seems fair for the price of the bike.

Trek use the Bosch Performance CX motor, with a 500Wh PowerTube battery. Trek believes this is the motor with the best global backup and consistence in supply.

The fork is a 160mm Fox Performance 36 with the GRIP damper and the G2 Geometry 51mm offset. The chassis is the e-bike optimised version, which is a touch stiffer (and heavier) than the standard one.

The rear suspension is controlled by a RockShox Deluxe RT3 RE:aktiv shock. This effectively has a platform that keeps the shock stable through rider inputs, but opens on impacts – the idea is that it’s good for pedalling, but is also responsive to trail debris inputs.

Bontrager’s Powerline Comp wheels are alloy and wide. They’re also DH certified, but are built with e-MTBs in mind. On the Powerfly LT 9 they’re paired with Bontrager XR4 tyres in a 2.8in width.

There’s a SRAM GX shifter, which is the e-MTB version allowing only one shift at a time, with a GX Eagle mech. The cassette is the new NX Eagle version with an 11-50t range — this is the only Eagle cassette rated for e-MTBs, hence its use. There’s then an X1 alloy crank attached to the Bosch motor.

Shimano’s new four-pot XT brakes provide the stopping power, and Bontrager provides the remainder of the finishing kit.

Trek Powerfly LT 9 ride impressions

While the Bosch motor has a number of modes, I kept the bike largely in the e-MTB mode, which is a relatively recent addition to the software.

It’s a more intuitive, natural-feeling mode than the simple Eco/Tour/Boost modes, and gives finer control of the power to the rear wheel, as it adjusts its power output between Eco, Tour and Boost automatically, depending on gradient and cadence.

The bike, with its long chanstays and chunky 2.8in tyres does climb very well. On steep climbs there’s minimal wandering or lifting from the front wheel, while the back end seems to dig in to the dirt. When things get twistier uphill, there doesn’t seem to be any noticeable disadvantage to that long rear-end either.

I like Trek’s rear suspension, the system works well on a wide range of trails, and the RE:aktiv system does seem to do a fair job of keeping the back end pretty stable. While more noticeable on a bike such as the Fuel EX , on an e-MTB, keeping things controlled is still important.

On both high-frequency chatter and big hits, the suspension remains composed, meaning the tyres are better equipped to do their job.

Up front the Performance 36 did a solid job. The e-MTB-specific chassis is stiff, and the simple GRIP damper is pretty smooth – aided by the additional mass of the bike, which always seems to make suspension feel that little bit better.

The long back end is a constant across the size ranges, and so while the front end of the large isn’t super long, it’s still a relatively balanced-feeling bike. Riders looking at smaller frames might find that length bias shifts quite far rearward as the bikes get smaller.

The integrated battery keeps the centre of mass relatively low, which is beneficial for cornering, as the bottom bracket isn’t super slammed.

While the head angle is relatively slack, it was perhaps cornering where the Powerfly LT 9 was most likely to come unstuck, and that’s just because I found the XR4 tyre a little too rounded for my tastes — there’s not a super-aggressive shoulder tread, so the front wheel didn’t always have that much bite when leaned over.

Stop-and-go functionality from Shimano’s bigger XT brakes and SRAM’s Eagle group was as competent as ever too. I had no bite-point issues with the XT brakes, and the single shift GX Eagle shifter makes a lot of sense on an e-MTB.

Bontrager’s finishing kit is as good as it ever is, though I was happy to hear there’s been an update on the Line dropper post, which Trek says should be more durable and serviceable.

Trek Powerfly LT 9 ride early verdict

Improving integration of the battery makes the Powerfly LT 9 a really smart proposition. If you’re looking for a long enduro-focused e-MTB then you might be looking elsewhere, but this is a well-balanced bike that still feels comfortable when you let off the brakes and let gravity do its thing.

Title : Active carbons as nanoporous materials for solving of environmental problems

However, up to now, the main carriers of catalytic additives have been mineral sorbents: silica gels, alumogels. This is obviously due to the fact that they consist of pure homogeneous components SiO2 and Al2O3, respectively. It is generally known that impurities, especially the ash elements, are catalytic poisons that reduce the effectiveness of the catalyst. Therefore, carbon sorbents with 5-15% by weight of ash elements in their composition are not used in the above mentioned technologies. However, in such an important field as a gas-mask technique, carbon sorbents (active carbons) are carriers of catalytic additives, providing effective protection of a person against any types of potent poisonous substances (PPS). In ESPE “JSC "Neorganika" there has been developed the technology of unique ashless spherical carbon carrier-catalysts by the method of liquid forming of furfural copolymers with subsequent gas-vapor activation, brand PAC. Active carbons PAC have 100% qualitative characteristics of the three main properties of carbon sorbents: strength - 100%, the proportion of sorbing pores in the pore space – 100%, purity - 100% (ash content is close to zero). A particularly outstanding feature of active PAC carbons is their uniquely high mechanical compressive strength of 740 ± 40 MPa, which is 3-7 times larger than that of  such materials as granite, quartzite, electric coal, and is comparable to the value for cast iron - 400-1000 MPa. This allows the PAC to operate under severe conditions in moving and fluidized beds.  Obviously, it is time to actively develop catalysts based on PAC sorbents for oil refining, petrochemicals, gas processing and various technologies of organic synthesis.

The Trek Powerfly LT 9.9 Plus is the result of several years of evolution. In this latest iteration, the bike features a classy carbon frame, a smartly integrated battery and the proven Bosch Performance CX motor. Will the bike still manage to convince our test riders?NEW: Before we get into the review, we would like […]

Excellent suspension

Balanced, composed handling

Good climbing capabilities

Front too low on steep descents

Cumbersome in tight sections

If I had to think of one common theme that continually came up during our time with the Powerfly, that would be it—too damn fun. Over the months we’ve had this bike, we’ve done it all and it does it all with ease.

Up hill or down, ebikes take an absolute beating, so the new Trek Powerfly 9 has a beefed up the parts package to handle the additional abuse.

Suspension, brakes and tyres are all on point. New battery layout is neat and easy to use.

Could have more generous reach measurements and shorter stems on all sizes.

Trek’s new 2019 Powerfly gives no mixed messages about its intentions. It is chunky, long, robust and built like a tank. With 160/150mm of travel, 40mm wide rims with 2.8″ tyres, e-bike specific FOX 36 the spec is undoubtedly up for a thrashing, and the chassis also. The newly integrated battery does wonders in making a …

Built tough.

Bosch E-MTB setting feels natural.

Fearless climber.

Length detracts from agility.

Heavy to move around.

Bosch Purion display does not have an active Micro-USB port, the PowerTube 500 is heavier than the older PowerPack design, longer wheel base isn't as nimble and the motor integration is flat vs. angled up (unless you get the carbon model), the motor is heavier than the competition, produces more noise, introduces some drag when unpowered

The long back end is a constant across the size ranges, and so while the front end of the large isn’t super long, it’s still a relatively balanced-feeling bike.

The Trek Powerfly is a very well sorted package and was one of the first e-bikes to win us over.
