Les qualités de pilotage du 29" en plus de la puissance constante de Bosch CX.
L’E-Juke+ avance vite grâce à son puissant couple de 85 Nm, mais aussi parce que nous l’avons équipé de roues 29" au très bon rendement et au pilotage facile Les autres composants fonctionnels de la fourche suspendue RockShox au changement de vitesse précis Shimano Deore XT/Deore 12 vitesses ne font qu’améliorer les performances. Et pour faire durer le plaisir encore plus longtemps, une grosse batterie de 625 Wh a été installée à l’intérieur du triangle avant.
Semi-rigide électrique équilibré à géométrie confortable
Système Bosch G4 Performance Line CX Cruise et batterie 625 Wh intégrée
The largest e-bike battery to date from Bosch is the PowerTube 625. It pushes the pursuit for even longer range to a new level. With an energy content ("capacity") of 625 watt hours, it is good for almost any extended tours you can imagine. To help ensure it stays that way for a long time, we keep it well protected in the voluminous downtube of our top e-bike models.
Bosch G4 Performance Line CX Cruise
Smaller, lighter, more powerful - there is no way around the new Bosch G4 (for 4th generation) Performance Line CX for high-end e-bikes. It supports its riders with a maximum of 340 % of their own pedal force and brings 75 Newton meters of torque into play. The engine power is dosed particularly smoothly in the so-called "E-MTB" mode, when the respective optimum support level is automatically engaged, because the fine sensors read the rider's request from the soles of his or her feet.
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.
Hydroforming (MTB)
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 (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.
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.
Abus YourPlus™
One key, any number of locks - the Abus "YourPlus™" program makes it possible to get keyed-alike locks with Plus lock cylinder. This is practical especially with e-bikes, as there are several locks on the bike: on the battery, as a frame lock and optionally an additional lock for connecting the bike to a fence or the like. Thanks to Abus YourPlus™ they can all be operated with a single key.
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.
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.
4-piston disc brakes
The demanding riders of high-end MTBs and touring e-bikes - with or without "E" support - are satisfied with nothing less than the most powerful hydraulic disc brakes in terms of braking performance and riding safety. They have 4 pistons per caliper instead of 2, and their larger brake pads can withstand much more heat, making them almost immune to fading (less friction due to heating).
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.
Comme l’autonomie d’un pedelec dépend de nombreux facteurs, nous recommandons le BOSCH Range Assistant. Pour plus d’informations sur les pedelecs et leur autonomie, rendez-vous sur notre FAQ, la foire aux questions.
