Exquisite 14-speed menu

For the E-14, STEVENS engineers have combined all their know-how and the finest components to create an E-bike in a class of its own. 85 Newton meters of Bosch CX power meet one of the most robust hub gears on the market: the Rohloff Speedhub. Its electronic actuation is fully integrated into the motor management to realize the fastest, smoothest gear changes. So much forward drive is stopped by a high-quality Tektro 4-piston brake system front and rear. For unclouded riding comfort provide, among other things, the harmonious STEVENS geometry, a sensitive suspension fork and a suspended and even lowerable seatpost. And it is really low maintenance by the innovative Gates CDX carbon drive belt, which puts conventional chain drives in terms of simplicity and longevity easily in the shade.

  • High-end pedelec with electronic 14-speed gear hub, automatic downshift and Gates carbon drive
  • Powerful Bosch G4 Performance Line CX system (250 W/85 Nm) plus integrated 625 Wh battery
  • Stable Tektro 4/4 piston disc brakes
  • Wide tires + adjustable seatpost = extra comfort!
  • Highly functional commuter specs to include LED front beam (120 Lux!)

Technology

Rohloff E-14 gear hub

The electronic Rohloff E-14 sets standards for E-bike shifting. In combination with the smart eShift function of the Bosch drive unit, this results in a uniquely fast, error-free shifting performance: at the touch of a button, the drive unit takes the load off the system and the Speedhub hub shifts gears. If the button is held down, all 14 gears can be shifted through in a quick 3-gear sequence. And when you stop at a traffic light, the system automatically shifts back to a previously selected starting gear. But it’s not just the electronics that are impressive, the mechanics are too: there are Speedhub hubs with a service life of over 100,000 kilometres. And there are tens of thousands of everyday and long-distance cyclists who never want another gear again. Maintenance requirements? A small oil change per year. Nothing more.

Belt drive

Belt drive

With a belt drive, a sturdy belt transmits the drive from the crank to the sprocket of the drive wheel. Although the non-separable design of the belt requires a STEVENS frame with a separable right seat stay as a special measure, the advantages are convincing: noticeable weight savings, silent running and significantly lower maintenance requirements.

Suspension seat post with drop function

Comfort to the power of two: The Oxygen E-Scorpo DPR-S-E can not only be lowered by up to 100 mm for more comfortable mounting and dismounting using the handlebar remote control – it also increases riding comfort with its built-in suspension.

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.

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.
