When you hop on the new E-Cayolle, you’ll immediately enjoy the energetic support of Bosch’s new top model Performance Line CX with up to 75 Newton meters of torque. It’s fed by the 500Wh PowerPack battery that’s semi-integrated into the down tube. When pedaling power is combined with that of the motor, you are pushed forward with full control as the bike is equipped with purely proven components. At just over 21kg, the E-Cayolle is THE lightweight among STEVENS' e-hardtails.
Solid e-hardtail with comfort geometry and size-specific 27.5" or 29" wheels
Bosch G4 Performance Line CX Cruise system w/ semi-integrated 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.
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.
Boost Rear Axle Spacing
This bike adheres to the "Boost" standard with 148 mm axle spacing. And there are good reasons for that. Rear wheel stiffness increases by 20 % which is especially beneficial in large 29" wheels. And there is more space for voluminous studded tires to give you more control and fun an the trail.
eShift (Pedelec)
Here two world market leaders collaborated to help pedelec riders have more fun. Via the eShift interface Bosch motor and Di-2 shifting work like magic. Instead of waiting for the command from the rider they automatically shift to the optimal gear smoothly and fast as lightning - always to keep the pre-selected preferred cadence. And when stopping on a red light the system will automatically shift to a pre-selected gear.
Tapered Seat Tube (MTB)
The seat tube tapers from top to bottom. At the top it fits a slim 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.
Speed sensor integrated in the dropout
This view is only available when the rear wheel is removed - otherwise the sensor, which gives the e-bike drive system the decisive information about the current speed, is perfectly integrated and well protected in the rear left dropout. The not so rare error that the incorrectly positioned spoke magnet slows down the motor support is thus combated very effectively.
Smooth Welded
Additional step in welding. The first, rippled weld, typical for aluminium, is covered with a second smoother weld. This not only improves looks but also lowers the risk of notches in this spot, which makes the frames more durable.
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.
Tapered Steerer / Tapered Headtube (MTB)
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 (MTB + ATB + Pedelec)
"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.
E-thru Rear Axle
This abbreviation stands for Shimano's thru-axle standard for rear stays that integrates a thread into the dropout. As a result, the 12mm thru axle provides outstanding rear triangle stiffness and utmost precision in brake disc alignement to prevent annoying brake rub.
Hydroforming (MTB)
Using water pressure aluminium tubes are transformed from their original round shape into their ideal shape determined by STEVENS engineers and designers.
Plug in cover
The cover of the USB-C plug in is perfectly integrated into the bike frame. The high quality of the cover ensures a clean, tidy look on the one hand and easy handling on the other. Especially in the sensitive area of the plug in, it is important that it is optimally protected from dirt and other external influences.
