Trek Rail 9.9 E-MTB on test: Expensive but (almost) perfect E-MTB

July 22, 2020 by Michael Faiss

TrekRail 9.9

Test: With just under 11.000 At €9.9, the Trek Rail XNUMX is one of the most expensive bikes in our test field. But in return, buyers get an e-MTB that deserves the "high-end" label in every respect: This applies to the sophisticated carbon frame with clever features like the side-mounted battery removal and the top tube-mounted Kiox display, as well as to the high-quality components in every respect. Highlights are certainly the SRAM AXS drivetrain with wireless Reverb seatpost and the in-house carbon wheels.

Sometimes you just get those bikes with the "wow factor." The Rail 9.9 from US manufacturer Trek was one of those bikes for us: Somehow simple and striking at the same time, with an incredibly clean look and an overall very high-quality appearance, it makes quite an impression even when stationary. Unfortunately, the price is also "wow." Just under 11.000 You'll have to put down €9.9 for this premium e-MTB. Let's get this straight: The Rail XNUMX repays this high purchase price with almost perfect performance and was one of the very few bikes in the test field where we couldn't identify any real weaknesses.



The wireless Sram components also contribute to the extremely clean look of the Rail 9.9. In addition to the gears, the retractable reverb support is controlled without any cables, lines or trains.

Low weight and clever battery removal

With a light full carbon frame and high-quality components, Trek has managed to reduce the weight of its E-MTB top model in the size L we tested to well under 22kg. Other E-MTBs in this weight class often make compromises, for example when it comes to battery capacity - the Rail 9.9, on the other hand, has a fully grown power tube with 625Wh in the down tube. This brings us to one of the special features, the removal of the battery. The energy storage device is removed to the side together with the cover mounted on it. This works very well in practice, but has a small disadvantage: If you have a second battery in your backpack for longer tours, you have to unscrew the cover when changing it.

The integration of the Bosch Kiox display is unique. Trek installs this on the top tube instead of on the handlebars. Although it is not always in view there, it is very well protected in the event of a fall.
Double protection: The Knock Block headset together with the robust rubber buffers on the down tube prevent the fork crown from leaving unsightly marks in the event of a crash.


The battery powers a Bosch CX motor, which plays a key role in the very good riding characteristics of the Trek E-MTB on the flat and uphill. No less important for this, however, is the perfectly balanced seating position. You sit in the center of the bike, which is just as comfortable on demanding trails as it is on tricky climbing passages. The latter are also fun thanks to the wireless Sram AXS components: the levers for the seat post and rear derailleur, which initially took some getting used to, turn out to be real fun after a few meters of practice. During the climb, you can comfortably place your thumbs in the appropriate recess and operate the dropper support or change gear within fractions of a second with minimal effort.

Lively but smooth on the trail

The fact that the Rail also performs well on the downhill trail is not least due to the very well-functioning Rockshox suspension. This manages to tickle the maximum out of the 160mm or 150mm spring travel without the need for hours of adjustment orgies. The lively yet smooth-running handling harmonises excellently with the stiff carbon wheels on which Bontrager's own tires are mounted. If we were to look for the hair in the soup: It would probably be the tires, which cannot quite keep up with the top dogs from Schwalbe and Maxxis in terms of grip.



Last but not least, we noticed the successful cockpit. Due to the omission of cables for gears and dropper support, it is visually tidy anyway and also ergonomically a real benefit. We also liked the integration of the Kiox display into the top tube. Although it is no longer entirely in the field of vision, it is very well protected in the event of a fall.
