As good as it can get.

For our new top model STEVENS' engineers combined all their know-how with the finest components to create this premium e-bike. 75Nm from Bosch's leading CX motor are matched to a Rohloff Speedhub, the only gear box able to withstand these forces even after long-time use. Its electronic operation is fully integrated into the motor management system to enable the fastest, smoothest shifting possible. A well-rounded geometry, sensitive suspension fork and suspension seatpost (with dropper function!) are good for unadulterated ride comfort.

  • High-end pedelec with electronic 14-speed gear hub, automatic downshift and Gates carbon drive
  • Powerful Bosch G4 Performance Line CX system (250 W/75 Nm) plus integrated 625 Wh battery
  • Magura 4-piston disc brake
  • Wide tires + adjustable seatpost = extra comfort!
  • Highly functional commuter specs to include LED front beam (120 Lux!)

Rohloff E-14/Speedhub

The electronic Rohloff E-14 sets a benchmark for e-bike shifting. Combined with the e-shift function of the Bosch motor it offers a unique, fast and faultless shifting performance: One push of a button - the motor will immediately reduce power and the Speedhub will change gears. Hold the button and the hub shifts all 14 gears in three-gear steps at a time. And when stopping on a red light it will automatically shift to a pre-selected gear.

But not only the electronics, also the mechanics delights the rider: There are Speedhubs out there having run more than 100.000km. And there are thousands of everyday and long-distance riders who never ever want to use any other way of shifting again. Maintenance? Maybe one oil change per year - that's it.

Bosch G4 Performance Line CX Cruise

Bosch G4 Performance Line CX Cruise engine

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.

Bosch Kiox-Display

Bosch Kiox-Display

The innovative Kiox display is attached to the stem with a user friendly magnetic holder. It provides ambitious e-bike riders with all kinds of interesting information like self-generated power and heart rate (with optional Bluetooth heart rate chest belt).

PowerTube 625

PowerTube 625 Battery

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.

New PT6 frame

New PT6 PowerTube frame

Its powerful down tube fits the Bosch battery with the longest range. And the frame geometry has been further refined - for the eye, by adapting all tube dimensions to the crucial down tube. And for an even more harmonious riding experience, the tube lengths have been optimized and the cockpit with steeper stems has been adapted to a pleasantly upright sitting posture.

Belt Drive

A belt drive, as the name suggests, uses a drive belt instead of a chain to transfer power from the cranks to the rear wheel. Since the belt cannot be split like a chain the special STEVENS frame utilizes a splittable seat stay, but the advantages are convincing: lower weight, silent operation, almost endless longevity without any maintenance.

Integrated Pannier Rack Mount dropout

In collaboration with pannier rack specialists Tubus/Racktime STEVENS' engineers have developed a dropout that also serves as an elegant pannier rack mount. It not only looks fantastic, it also ensures that forces caused by luggage or large amounts of groceries are evenly transmitted inot the frame - resulting in a more stable and safer design.

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.

Suspension seat post with dropper function

Suspension seat post with dropper function

Comfort times two: The Kind Shock 860i can not only be lowered by up to 75 mm with the handlebar remote control for easier mounting and dismounting - with its built-in suspension it also enhances riding comfort.

IQ-X Head Light

The IQ-X head light range from Busch+Müller has a very bright, large and evenly lit light beam. The smaller, more elegant XS version outputs 70 Lux. The middle version IQ-X outputs 100 Lux. And the strongest IQ-XMF outputs 120 Lux on full beam, 80 Lux on dipped beam.

Even when you can't see the strut that connects the pannier rack to the fender - it is there. The strut runs below the fender and provides - in connection with the rack mounted to the fender - more stability and lateral stiffness.

Up to 55mm tire clearance

Up to 55mm tire clearance

When you ride on roads with less than perfect surface, you can now mount up to 55mm wide tires - e.g. Schwalbe’s current no.1, the Marathon E-Bike Plus - and benefit from maximum comfort and flat protection provided by its extra large air volume, as it can now be ridden with even lower tire pressure. Frames and forks are already prepared to fit these wider tires.

Abus YourPlus™

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.

Selle Royal eZone saddle

Selle Royal eZone saddle

Comfort plus: The Selle Royal eZone saddle, specially designed for e-bikes, stands out due to its high level of seating comfort, solid support (when accelerating) and practical carrying handle.

4-piston disc brakes

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).

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.

Hydraulic Disc Brakes (Trekking)

There is no brake system more reliable than hydraulic disc brakes - that is why we strongly advice everyone, who is riding their bike (nearly) 12 months a year to choose one of our models with a disc brake. Brake power is easy to modulate and does not fade a bit in the wet. Also the brakes are almost maintenance-free. And your local STEVENS dealer will gladly explain to you what you need to take care of when removing and re-installing a wheel.
