Fit For Fun.

Even some motorbikes don't have as much torque (75Nm) as the powerful Bosch Performance Line CX motor (4th generation!). Prestigious shift and brake components like these are usually found on high-quality mountain bikes. But its true potential is brought forward by the STEVENS add-ons - mainly the new frame with super-low (and perfectly protected) battery placement and sporty-but-comfortable seating position.

  • Sportive E-cross bike with low center of gravity
  • Bosch G4 Performance Line CX Cruise system w/ 75 Nm torque and 500 Wh battery
  • Innovative Bosch Kiox display
  • Shimano Deore XT: 12-speed gears plus hydraulic disc brakes
  • Fast & grippy Continental Double Fighter III tires

Tecnologia

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.

QR15 Front Thru-Axle

"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.

Bosch Kiox-Display

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).

Semi-integrated battery

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 G4 Performance Line CX Cruise

Bosch G4 Performance Line CX Cruise engine

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.

Hydroforming

Using water pressure aluminium tubes are transformed from their original round shape into their ideal shape determined by STEVENS engineers and designers.

Speed sensor integrated in the dropout

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.

Tapered Steerer / Tapered Headtube

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.

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.

E-thru Rear Axle

E-thru Rear Axle at E-Cayolle

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.

Up to 54mm tire clearance

Up to 54mm tire clearance

When you ride on roads with less than perfect surface, you can now mount up to 54mm wide tires - e.g. Schwalbe’s current no.1, the Marathon E-Bike Plus - and benefit from maximum comfort and flat protection provided by its extra large air volume, as it can now be ridden with even lower tire pressure. Frames and forks are already prepared to fit these wider tires.

On tarmac and in less extreme terrain Stevens' e-'crosser E-8X is super fun to ride thanks to a powerful motor and well-tuned set-up. The lack in comfort will be no problem for its more sports-oriented riders.
