The E-Wave paves the way.

The way off-road supported by 63Nm (46lb-ft) of torque from Bosch. For an entry-level price it still offers a reasonable mix of components highlighted by versatile 2.6" Smart Sam tires. Due to its new comfort geometry matched to 120mm of travel the changing from a conventional to an e-driven mountain bike is easy.

  • Entry-level e-hardtail w/ enormous frame size range
  • Strong Bosch Performance Line Cruise system w/ 63 Nm torque and 400 Wh rechargeable battery
  • SR Suntour 120 mm suspension fork w/ thru-axle
  • Schwalbe Smart Sam tires in new 27.5x2.6" format
  • Reliable Shimano Alivio 9-speed gears

Technology

Boost-Standard Fork

What is right for the rear wheel is even more important at the front wheel - because steering precision matters. This is why STEVENS uses suspension forks and hubs with extra wide axle spacing for all its 29er fullies, the Whaka+ ES and the trail rocket Sonora SL. These 110mm of axle spacing are called "Boost" or "Plus" and stand for lots of added lateral stiffness plus space for extra wide studded tires.

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. This means better steering precision on the trail and higher longevity.

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.

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.

Tapered Seat Tube

The seat tube tapers from top to bottom. At the top it fits a slim 27.2mm seatpost that offers some flex and therefore increases comfort especially when riding over rough ground. At the bottom the large diameter nicley flows into the bottom bracket shell and downtube to provide great stiffness and drivetrain efficiency.
