A sub 20kg pedal assist bike?

It must be a STEVENS. In the E-6X, motor and battery are positioned as central and low as possible, thereby adopting its cyclocross cousins' nimbleness – even with the ladies' model! But what do you need numbers and technical data for when it's a sunny day and there's hours of effortless gliding over all kinds of terrain ahead of you?

  • Agile E-cross bike with low center of gravity even more comfortable sitting position
  • Air suspension fork w/ tapered steerer and thru-axle
  • Bosch Performance CX system plus Shimano Deore 10-speed drivetrain
  • Precise Shimano trekking disc brakes
  • Very low total weight

Technology

Bosch Performance Line CX-Antrieb

Das muss man erlebt haben, wie dieser speziell für Gelände-Pedelecs konzipierte Motor schon bei nur 20 Kurbelumdrehungen/Minute bärenstarken Schub bringt. Mit maximal 75 Newtonmeter Drehmoment und bis zum 3-fachen der Fahrer-Power ist der CX von Bosch auf Trails aller Art ein guter und zuverlässiger Freund. An STEVENS Bikes – leicht gedreht – schön in den Rahmen integriert.

QR15-Steckachse vorn

Die „15“ steht für den Achsdurchmesser, das „QR“ für „Quick Release“, also Schnellspanner – und zusammen für die funktionellste Methode, das Vorderrad in der (Feder-)Gabel zu verankern. Die Vorteile sind bestechend: hohe Steifigkeit, präzise Bremsscheiben-Positionierung und kinderleichte Bedienung. Also stattet STEVENS fast alle Mountainbikes und sogar die hochwertigsten Trekking-, Crossbikes und Pedelecs damit aus. Vor allem bei den 29“-MTBs wird sogar noch die Einbaubreite erhöht – von 100 auf 110 mm, das ist noch steifer.

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

Extra Energy SEHR GUT

Be it as an MTB or 'cross bike the light E-6X rides also fantastically without motor support. With a powerful motor and good specs, this means a »Very Good« in the sport pedelec off-road ranking.
