Fun and endurance.

The new E-Tremalzo celebrates its premiere in the 2,600 Euros class - and thanks to its smooth Bosch Performance Line motor and large-capacity 500Wh battery, semi-integrated into the down tube, it doesn't get tired when a tour lasts longer than planned - because it's so much fun. Responsible for that are our comfort geometry, a sensitive SR Suntour suspension fork and versatile Smart Sam tires.

  • Updated entry-level e-hardtail w/ trail-worthy geometry
  • Smooth Bosch G3 Performance Line Cruise system w/ semi-integrated 500 Wh battery
  • SR Suntour 100 mm suspension fork w/ thru-axle
  • Proven Shimano Deore/Alivio 9-speed gears
  • Size-specific Schwalbe Smart Sam tires

Technology

Bosch G3 Performance Line Cruise

Bosch G3 Performance Line Cruise engine

When it says "Performance" on the outside, lots of power is inside: This power house delivers 250 Watts and 65 Nm. For your e-bike this means a sufficient support in any kind of situation – exactly what you have asked for. And the latest, 3rd generation of this drive system from Bosch (identified by its standard-size chainring) also shines with a barely perceptible noise as well as minimal resistance if you once again want to cross the 25kph threshold under your own power.

Semi-integrated battery

Semi-integrated battery

This is what successful integration looks like: A Bosch PowerPack battery is concealed under this matt black cover, which is harmoniously adapted to the shape of the frame - optimally protected from the weather and cold, so it is clean and dry and can be easily recharged in the office or home, even after riding in the rain.

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 this bike. 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.

500 Wh Battery

This will decide success or failure of e-mobility. That's why STEVENS uses batteries with a huge 500 Watt-hour capacity in all its top-notch pedelecs for up to 215 km of range (according to the manufacturer, please refer to the Bosch range calculator for more exact results). This is possible even without a weight penalty: Compared to the old PowerPack 400, the new Bosch PowerPack 500 is just 100 grams heavier. This huge "fuel tank" is our premier recommendation for pedelec riders who don't shy away from the hilliest of itineraries.

Hydroforming

Using water pressure aluminium tubes are transformed from their original round shape into their ideal shape determined by STEVENS engineers and designers.

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 Front Thru-Axle

"15" stands for the diameter in millimeters, "QR" for quick release. Combined they are the most useful method to fix the front wheel to the (suspension) fork. With convincing advantages: high stiffness, precise positioning of the brake disc and super-easy handling. So STEVENS specs almost all its mountain bikes and even high-quality trekking bikes, cross bikes and pedelecs with a thru-axle. Additionally, especially with 29" MTBs axle spacing is increased from 100 to 110 mm which makes the design even stiffer.
