STEVENS' X-Cross genes and a low weight of under 23kg make this e-bike the ideal companion for fast-paced rides. Thanks to the power of the latest Bosch Performance CX motor even the longest stages will turn into a purely pleasant experience. Shimano Deore XT disc brakes with 180mm diameter front and rear always keep the E-8X Tour, its rider and luggage under control when it's gliding over streets, bike paths and gravel roads on its perfectly profiled Continental tires.
Fast touring pedelec with high quality specs
Bosch G4 Performance Line CX Cruise system with innovative Kiox display
500 Wh battery for touring-capable range
Shimano Deore XT: 12-speed gears plus hydraulic disc brakes
Fast & grippy Continental Double Fighter III tires
Smaller, lighter, more powerful - there is no way around the new Bosch G4 (for 4th generation) Performance Line CX for high-end e-bikes. It supports its riders with a maximum of 340 % of their own pedal force and brings 75 Newton meters of torque into play. The engine power is dosed particularly smoothly in the so-called "E-MTB" mode, when the respective optimum support level is automatically engaged, because the fine sensors read the rider's request from the soles of his or her feet.
Semi-integrated battery
This is what successful integration looks like: A Bosch PowerPack battery is concealed under this matt black cover, which is harmoniously adapted to the shape of the frame - optimally protected from the weather and cold, so it is clean and dry and can be easily recharged in the office or home, even after riding in the rain.
Bosch Kiox-Display
The innovative Kiox display is attached to the stem with a user friendly magnetic holder. It provides ambitious e-bike riders with all kinds of interesting information like self-generated power and heart rate (with optional Bluetooth heart rate chest belt).
QR15 Front Thru-Axle (MTB + ATB + Pedelec)
"15" stands for the diameter in millimeters, "QR" for quick release. Combined they are the most useful method to fix the front wheel to the (suspension) fork. With convincing advantages: high stiffness, precise positioning of the brake disc and super-easy handling. So STEVENS specs almost all its mountain bikes and even high-quality trekking bikes, cross bikes and pedelecs with a thru-axle. Additionally, especially with 29" MTBs axle spacing is increased from 100 to 110 mm which makes the design even stiffer.
E-thru Rear Axle
This abbreviation stands for Shimano's thru-axle standard for rear stays that integrates a thread into the dropout. As a result, the 12mm thru axle provides outstanding rear triangle stiffness and utmost precision in brake disc alignement to prevent annoying brake rub.
Speed sensor integrated in the dropout
This view is only available when the rear wheel is removed - otherwise the sensor, which gives the e-bike drive system the decisive information about the current speed, is perfectly integrated and well protected in the rear left dropout. The not so rare error that the incorrectly positioned spoke magnet slows down the motor support is thus combated very effectively.
500 Wh Battery
This will decide success or failure of e-mobility. That's why STEVENS uses batteries with a huge 500 Watt-hour capacity in all its top-notch pedelecs for up to 215 km of range (according to the manufacturer, please refer to the Bosch range calculator for more exact results). This is possible even without a weight penalty: Compared to the old PowerPack 400, the new Bosch PowerPack 500 is just 100 grams heavier. This huge "fuel tank" is our premier recommendation for pedelec riders who don't shy away from the hilliest of itineraries.
Dropouts with integrated pannier rack eyelets
In collaboration with pannier rack specialists Tubus/Racktime STEVENS' engineers have developed a dropout that also serves as an elegant pannier rack mount. It not only looks fantastic, it also ensures that forces caused by luggage or large amounts of groceries are evenly transmitted inot the frame - resulting in a more stable and safer design.
Integrated pannier rack strut
Even when you can't see the strut that connects the pannier rack to the fender - it is there. The strut runs below the fender and provides - in connection with the rack mounted to the fender - more stability and lateral stiffness.
IQ-X Head Light
The IQ-X head light range from Busch+Müller has a very bright, large and evenly lit light beam. The smaller, more elegant XS version outputs 70 Lux. The middle version IQ-X outputs 100 Lux. And the strongest IQ-XMF outputs 120 Lux on full beam, 80 Lux on dipped beam.
Tapered Steerer / Tapered Headtube (ATB+Pedelec)
Fork shaft (or steerer tube) and head tube are tapered, meaning their diameter increases from top to bottom resulting in a conical shape. The diameter needs to be bigger at the bottom since this is where higher stress is applied - especially when the bike has a higher total weight due to luggage or an e-drive and battery. Also tapered steerers feature a smoother force transfer (like forces caused by hard braking) to the downtube than forks with a continuous 1 1/8" diameter.
Hydroforming (ATB+Pedelec)
Using water pressure aluminium tubes are transformed from their original round shape into their ideal shape determined by STEVENS engineers and designers.
Triple Butted, Double Butted
Meaning a frame tube has three or two different wall thicknesses along its length. Triple butted (TB) is the usual technology with STEVENS high-quality frames. Tubes with different wall thicknesses are optimally adjusted to certain ways of manufacturing or to withstand specific loads. Where the highest loads occur or where tubes are welded, walls are the thickest. Butted tubes allow frame weight to be lower by several hundred grams.
Hydraulic Disc Brakes (Trekking)
There is no brake system more reliable than hydraulic disc brakes - that is why we strongly advice everyone, who is riding their bike (nearly) 12 months a year to choose one of our models with a disc brake. Brake power is easy to modulate and does not fade a bit in the wet. Also the brakes are almost maintenance-free. And your local STEVENS dealer will gladly explain to you what you need to take care of when removing and re-installing a wheel.
Plug in cover
The cover of the USB-C plug in is perfectly integrated into the bike frame. The high quality of the cover ensures a clean, tidy look on the one hand and easy handling on the other. Especially in the sensitive area of the plug in, it is important that it is optimally protected from dirt and other external influences.
