Top touring city e-crosser

We have equipped our versatile E-Trekking and E-Allround frame with a sportier geometry especially for the E-8X Tour. This guarantees you a more active riding position on the bike for more agile riding behaviour on winding forest paths, over winding country lanes or simply "just" on your daily ride through the city. The large 725 Wh Bosch PowerPack battery, the powerful Bosch Performance Line CX motor and a SunRace-based 12-speed derailleur gear system with a wide gear range are a guarantee of riding fun on all routes - ideal for fast stages or steep climbs.

E-Trekking and E-Allround frame

Designed for use with the compact Bosch PowerPack batteries with a capacity of up to 800 Wh, the frames also impress with integrated cable routing and an integrated plastic parts concept. The battery cover, motor cover and chain guard merge into one another as if from a single mould. For a clean, uniform look and outstanding functionality.

180 kg gross vehicle weight

180 kg gross vehicle weight

The STEVENS E-bikes with the "Plus" suffix can weigh 180 kilograms including rider and luggage. Enough for even the strongest types and the most demanding tasks. The frames are designed to handle this load and have been thoroughly tested by the experts from the Zedler Institute for Bicycle Technology and Safety.

On/off switch with integrated USB-C charging socket

On/off switch with integrated USB-C charging socket

On the E-Inception models with Shimano drive and the large Darfon battery, a USB-C charging socket on the top tube – ensures that the smartphone, action camera or lighting system are powered for as long as the trail adventure lasts. Riders can also switch the system on and off in a smart and user-friendly way on the top tube.

QR15 thru axle

QR15 thru axle

The "15" stands for the axle diameter, the "QR" for "Quick Release" – and together for the most functional method of anchoring the front wheel in the (suspension) fork. The advantages are impressive: high rigidity, precise brake disc positioning and foolproof operation. STEVENS therefore equips all mountain bikes and E-MTBs as well as the highest quality trekking bikes, cross bikes and E-bikes with them. For (E-)MTBs in particular, the installation width has even been increased – from 100 to 110 mm, which is even stiffer.

E-thru rear axle

E-thru rear axle

This abbreviation stands for Shimano’s thru-axle standard for rear triangles, in which the threaded nut is integrated directly into the dropout. The 12 mm axle ensures outstanding rear triangle stiffness and absolutely precise positioning of the brake disc – this avoids annoying grinding noises.

Tyre clearance up to 50 mm

Tyre clearance up to 50 mm

If you frequently ride your E-bike on on less than optimal roads, you can fit tyres up to 50 mm wide – and then benefit from greater riding comfort and puncture protection thanks to their larger air volume, as you can now ride with lower tyre pressure. The frames and forks of these bikes are already prepared for this.

Dropouts with integrated pannier rack eyelets

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 if you can’t see the support of the pannier rack to the seat stays – it’s there. A strut runs under the mudguard and – in conjunction with the mudguard attached to the pannier rack – provides even more stability and lateral stiffness.
