Fit For Fun.

Even some motorbikes don't have as much torque (75Nm/55lb-ft) as the powerful Bosch Performance CX e-motor. 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 motor mounted in an angled position, super-low battery placement and sporty-but-comfortable seating position.

Technology

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.

QR15 Front Thru-Axle

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

Hydroforming

Optimum load-specific shape by oil or water pressure.

Tapered Steerer / Tapered Headtube

Tapered headtube for optimum force transfer and steering precision.

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.

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.

Hydroforming

Using water or oil pressure aluminium tubes are transformed from their original round shape into their ideal shape determined by STEVENS engineers to perfectly withstand any load without any weight penalty. Riders of allround bikes and pedelecs will benefit from a better stability caused by hydroforming even when they are touring with heavy luggage.

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 more reliable brake system than hydraulic disc brakes - that is why we strongly advice everyone, who is riding their cross, trekking- or city bike 12 months a year to choose one of our models with the „DISC“ suffix. 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

05/2017

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.

Pleasantly uncomplicated E-crosser for any occasion with balanced, cultivated ride characteristics to make every ride a pleasure.

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.!
