Trek Powerfly 9 LT Plus – In Brief
That luminous red is loud but not garish.
Those who know Trek will be well aware of the quality of the brand. This holds fast with this model too. The frame, with filed weld beads, slick semi-integrated battery, smart detailing and that luminous red puts the quality of this frame at the top of the list of what is currently available on the market.
The Trek Powerfly 9 LT Plus has everything that a eMTB needs: fat 27.5” plus tyres, plush suspension with 150mm of travel with a Fox 36 Fork and RockShox Deluxe RT3 shock, and the by now common sight of 8-speed SRAM EX1 gearing. The eBike is powered by the capable Bosch Performance CX motor.
We were also presented the rest of the 2018 Trek Powerfly range which you can see here.

Motor & Battery
Details about the Bosch Performance CX
The product managers at Trek aren’t taking chances by choosing the Bosch Performance CX motor. Dominant on the market and of the highest quality, this motor can be instrumental for customers making a purchase decision. As we have come to expect, the Bosch motor pushes the bike forward obediently, and as we are used to, helps make rapid progress over the trails.
- Motor: Bosch Performance CX
- Battery: 500 Wh
- Leistung: max. 250 Watt
- Display: Bosch Purion
40.4 km / 819 metres ascent
1 h 40 min
Quoted figures for range tend to be on the optimistic side, so we like to test bikes for ourselves, draining a whole battery and seeing how far the bike will go. For this test we managed 40.4km and 819 metres of ascending, staying in the highest power setting throughout. Please note that these values in no way represent rigorous or normalised testing, instead they should be seen as ballpark figures. Using lower assistance modes increases the range significantly too.
The battery is not completely hidden in the downtube.
We are definitely fans of fully integrated batteries, but what Trek have done here has its own charm and has yet to find an equal in the “world” of semi-integrated batteries. Around 70% of the volume of the Bosch PowerPack disappears into the downtube and is integrated aesthetically by a plastic cover. This means the battery seems significantly less massive than that of competitors, and more importantly it remains compatible with older Bosch PowerPack batteries if the need arises. Of course the plastic fairing will be missing, but this shouldn’t really matter in an emergency.
Trek Powerfly 9 LT Plus – Hands On
The slick and streamlined hydro-formed aluminium frame seems like it’s forged in one piece
It’s rare that a test bike draws the attention of everyone in the office when it’s unboxed, but this is exactly what happened with the Trek Powerfly 9 LT Plus. Trek shows with aplomb what it takes to create such a high quality frame and what this looks like in person. The slick and streamlined hydro-formed aluminium frame seems like its forged in one piece. The weld beads are beautifully smoothed and the paint job is flawless. Examining things more closely, we couldn’t find anything out of place. The Trek Powerfly 9 LT Plus shows itself proudly and could quite happily strut down the cat walk.
A particularly interesting feature is the Knock Block, effectively a steering limiter that prevents the handlebars twisting too far. This protects the top tube from scratches and impacts from the brake and gear levers.
We also feel it’s worth discussing the Mino Link. This flip-chip gives two geometry options for the Trek Powerfly 9 LT Plus. In high, the head angle is an already slack 66.5 degree, in the low position that slackens out another 0.5 degree along with dropping the bottom bracket slightly.
Trek Powerfly 9 LT Plus – On the trail
The upright seating position puts you in a good place for uphill performance
Steep ramps or long uphill sections don’t pose any challenge for this E-Bike. Thanks to the upright position it’s easy to maintain flow and speed on the way up the hill. It’s only when you stand up to pedal that you start to notice the RE:aktiv suspension start to bob. On technical sections the front wheel has a tendency to lift because it’s difficult to maintain weight over the front. Tight switchbacks are also a bit of a challenge, with the long wheelbase making playful flickability a little more difficult.
The tyres reach their limits too quickly.
With 150mm travel front and rear the Trek is definitely not a pure-bred downhiller so we were a little apprehensive taking it down the first steep trails. A few corners in we quickly found that we were staying off the brakes more and more and picking up a fair bit of speed. The Trek Powerfly 9 LT Plus stays planted and allows you to maintain a good deal of momentum. The sensitive rear with RE:aktiv suspension gives decent amounts of feedback and convinced us throughout our runs. Even on rougher sections the eMTB didn’t blow through all its travel and took steps, rocks and roots in its stride. Only the fitted Schwalbe Nobby Nic tyres put a damper on our need for speed. As the speed picks up, as corners get tight and as the ground gets looser there comes a point where it just gets too much and the tyres let go completely.
Suspension tailor-made for the trails.
The Trek Powerfly 9 LT Plus is very happy on the trail and passes that enthusiasm on to the rider. We got to grips with the setup very quickly and found that it didn’t need significant changes for different terrain. The rider position is central allowing for longer time spent on the bike in comfort. Changes in direction happen quickly and confidently thanks to the stiff frame and tricky sections can be dispatched with ease. Only the travel of the dropper post was a bit off-putting at times – we found we couldn’t get it far enough out of the way on some of the steeper sections we rode. That said, trails on this eBike are a hell of a lot of fun.
As with many other eBikes, we advise changing the saddle. The Bontrager saddle is premium and looks good, but we found on longer rides that it didn’t offer enough comfort for us. It makes sense to get a more ergonomic model that will suit you.
Our second tip concerns the tyres. We personally find 2.8” tyres a bit too sluggish and imprecise for such a high performance eMTB. We would prefer to see narrower 2.6” tyres.
Conclusion – Trek Powerfly 9 LT Plus
The Trek Powerfly 9 LT Plus fulfils its promise. The brand has shown us convincingly how high its production quality is and is putting a top-class eMTB into stores.
On the trail the Trek Powerfly 9 LT Plus gives an absolutely convincing ride: the rear is supple and active and smooths out the bumps of even the roughest of trails. The geometry is suited to aggressive and athletic riding and the component spec doesn’t compromise. The paint quality is second to none and the frame itself feels and looks premium. It’s only the size of the tyres and the limited travel of the dropper that curb our enthusiasm ever so slightly.
- High quality finishing
- Capable suspension
- Limited travel on dropper post
- Plus tyres feel sluggish and vague
About the Test
On our test runs we usually stay in the highest assistance mode and drain the battery completely at least once. We then publish our results on our Strava account.
Our loop has everything we need to test E-Bike capabilities:
- Tight uphill trails with roots, rocks and loam
- Flat trails with small climbing sections
- Fast and flowing downhills
- Long, loose trails downhill
E-Bikes are subjected to our route multiple times to allow us to draw our conclusions.
We tested the Trek Powerfly 9 LT Plus here:
- LOCATION: Trail-riding around Bamberg in Germany, and Brixen and Latsch in Italy. The riding provides narrow and tight trails with rooty, rocky sections, switchbacks, bikepark runs, rough rockgardens, steep technical uphills as well as flowing downhill sections.
