Technology

Bosch G4 Performance Line CX Cruise

Smaller, lighter, more powerful - thus ideally suited for high-end e-bikes.

Semi-integrated battery

This is what successful integration looks like.

Bosch Kiox-Display

The innovative Kiox display is attached to the stem with a user friendly magnetic holder.

QR15 Front Thru-Axle

The most useful method to fix the front wheel to the (suspension) fork.

E-thru Rear Axle

Thru-axle standard from Shimano for extra stiff rear triangles and precision in brake disc alignement.

Speed sensor integrated in the dropout

Rear left, well hidden …

500 Wh Battery

STEVENS uses batteries with a huge 500 Watt-hour capacity in all its top-notch pedelecs for up to 215 km of range.

Dropouts with integrated pannier rack eyelets

Ensures stable and secure attachment.

Integrated Pannier Rack Strut

Invisibly provides more stability and lateral stiffness.

IQ-X Head Light

Innovative light technology for maximum visibility in any condition.

Tapered Steerer / Tapered Headtube

Tapered headtube for optimum force transfer and steering precision.

Hydroforming

Optimum load-specific shape by water pressure.

Triple Butted, Double Butted

For light and stable frame: Frame tubes with thinner walls in the middle and thicker walls at the ends.

Hydraulic Disc Brakes (Trekking)

Braking power can be perfectly modulated anytime.

Bosch G4 Performance Line CX Cruise

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

"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.

Integrated Pannier Rack Mount dropout

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.

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

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

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.

Bike-Category 4 E

E-cross bikes

This category describes STEVENS E-cross bikes. They have 28-inch wheels with narrow tyres. The tyre width is 28 to max. 42 mm. STEVENS E-8X, E-6X and E-6X Tour.

The permissible overall weight (pedelec incl. luggage and rider) should not exceed 140 kg (308.6 lbs). Under certain circumstances this permissible overall weight can be further limited by the component manufacturers’ recommendations for use
STEVENS E-city and E-trekking bikes are designed for a trailer load of 40 kg (88.2 lbs) without and 80 kg (176.4 lbs) with trailer brake.
STEVENS E-cross bikes are intended for hard-surface terrain, i.e. for tarred roads and bicycle lanes or gravel field tracks, where the wheels do not lose ground contact. In addition, they are well suited for well paved gravel paths and forest roads as well as off-road trails with a slight slope where a temporary loss of tyre contact with the ground due to small steps may occur. They are not suitable for off-road use (mountain bike use), namely for all mountain, enduro, downhill (DH), freeride, dual slalom, downhill/freeride parks, jumps, drops and in bike parks etc.
Due to their design and fittings, STEVENS E-cross bikes are not always suitable for being used on public roads. If you want to use them on public roads, these bikes must be fitted with the prescribed equipment. Observe the traffic rules when riding on public roads. For more information read chapter “Legal Requirements for Riding on Public Roads” in your comprehensive STEVENS user manual on the enclosed CD-ROM.

Intended Use: Keep in mind that every bicycle or pedelec type is built for a specific intended use. Be sure to use your STEVENS pedelec only according to its intended use, as the STEVENS pedelec may otherwise not withstand the stress, fail and cause an accident with unforeseeable consequences! Using it for another than the intended use will also void the warranty.

Danger:

STEVENS bikes of the category 4 E are not suitable for off-road use, jumps, slides, stair riding, stoppies, wheelies, tricks etc.!
