Less is more

The entry into the E-Triton world, the 5.5.1, shines with an unobtrusive frame design and semi-integrated 545 Wh Bosch PowerPack battery. The frame is designed without a battery cover, which makes removing the battery child's play. The tried-and-tested Bosch Performance Line Drive Unit with 75 Nm torque provides plenty of forward drive.

  • Affordable all-round pedelec with 545 Wh battery
  • Smooth Bosch Performance Line drive unit
  • Load-capable designed frame tubes made of aluminium 6061
  • Sturdy air suspension fork w/ thru-axle & lockout
  • Reliable 10-speed drivetrain

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.
