Fun and endurance.

The E-Tremalzo Lady celebrates its premiere in the 2,700 Euros class - and thanks to its large-capacity 500Wh battery it doesn't get tired when a tour lasts longer than planned - because it's so much fun. Responsible for this are our comfort geometry, the sensitive SR Suntour suspension fork and versatile Smart Sam tires.

Lady-E-Hardtail with extra low standover height despite 120 mm of front travel
Strong Bosch Performance Line CX system w/ 75 Nm torque and 500 Wh rechargeable battery
SR Suntour 120 mm suspension fork w/ thru-axle
Schwalbe Smart Sam tires in 27.5x2.6"
Proven Shimano Deore/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.

500 Wh Battery

STEVENS uses batteries with a huge 500 Watt-hour capacity in all its top-notch pedelecs for up to 215 km of range.

Hydroforming

A bonus in steering precision and longevity.

Tapered Steerer / Tapered Headtube

Riders benefit from noticeably higher steering precision, almost without weight penalty.

Triple Butted, Double Butted

For light and stable frame: Frame tubes with thinner walls in the middle and thicker walls at the ends.

QR15 Front Thru-Axle

The most useful method to fix the front wheel to the (suspension) fork.

Tapered Seat Tube

Increases riding comfort and provides stiffness and drive-train efficiency.

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 fullies, as well as for the trail rocket Sonora and the alloy-hardtails Colorado and Sentiero. 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 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 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.

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.

Bike-Category 5 E

E-cross-country, E-marathon and E-touring mountain bikes

This category describes STEVENS E-cross-country, E-marathon and E-touring mountain bikes and is typically represented by STEVENS E-mountain bike hardtails and full suspension STEVENS E-bikes with short suspension travel. STEVENS E-Scope, E-Agnello, E-Juke, E-Cayolle, E-Wave, E-Stoke and E-Pordoi.

Instructions on intended use

The permissible overall weight (pedelec incl. luggage and rider) should not exceed 140 kg (308.6 lbs). Under certain circumstances the permissible maximum weight can be further limited by the component manufacturers’ recommendations for use.
For full suspension STEVENS E-mountain bikes and carbon bikes trailers are not permitted.
STEVENS E-cross-country, E-marathon and E-touring mountain bikes are suitable for off-road use, but not for blocked terrain, tricks, stair riding etc. as well as training and competitive use in the categories freeride, dirt, downhill. STEVENS bikes of this category can be used on surfaces permitted for bikes of the categories 1 and 3 and are in addition suitable for rough and unpaved terrains. Sporadic jumps are also included in the field of use of these STEVENS bikes. But particularly inexperienced riders doing jumps may land inappropriately, thus increasing the acting forces significantly which may result in damage and injuries. We recommend that you train your skills in a riding technique course. If necessary, ask your STEVENS dealer to inspect your STEVENS bike at shorter intervals than according to the service and maintenance schedule.
Due to their design and fittings, STEVENS E-mountain bikes of the category 5 E are not always suitable for being used on public roads. If you want to use them on public roads, these bikes must be fitted with the prescribed equipment. Observe the traffic rules when riding on public roads. For more information read chapter “Legal Requirements for Riding on Public Roads” in your comprehensive STEVENS user manual on the enclosed CD-ROM.

Danger:

STEVENS bikes of the category 5 E are not suitable for use on blocked terrain, for high and long jumps, slides, stair riding, stoppies, wheelies, tricks etc.!
