The Stevens E-Triton 9.9.1 Forma combines advanced electric bike technology with outstanding riding comfort and Stevens' extensive carbon expertise. Its most distinctive feature is the premium Carbon SL Fiber frame with an exceptionally low step-through design. This allows Stevens to offer the sporty E-Triton platform not only with a classic diamond frame but also in a particularly comfortable step-through version. The powerful Bosch Performance Line CX motor delivering up to 120 Nm of torque, electronic Shimano CUES Di2 11-speed drivetrain, and premium SR Suntour air suspension fork provide a dynamic and comfortable riding experience. With a standard Bosch PowerMore 250 additional battery, powerful Shimano four-piston disc brakes, and comprehensive touring equipment, the E-Triton 9.9.1 Forma is perfectly suited to daily commuting and extended cycling tours. The elegant Blue Black finish highlights its premium and contemporary design.
At the heart of the Stevens E-Triton 9.9.1 Forma is its high-quality Carbon SL Fiber frame with an exceptionally low step-through design. The Forma frame version eliminates the traditional high top tube, making getting on and off the bike particularly easy and comfortable. This is especially beneficial in city traffic with frequent stops, during everyday shopping trips, and on longer cycling tours. It is also an attractive choice for riders who value straightforward handling and maximum convenience. Despite its low step-through construction, the carbon frame offers excellent stability and precise, agile handling. Fully internal cable routing creates a clean appearance and emphasises the modern frame design. Weighing 24.6 kg without the additional battery and featuring a maximum permitted system weight of 140 kg, the E-Triton offers an excellent combination of comfort, stability, and everyday practicality. The Forma version is available in frame sizes S, M, and L.
Electric assistance is provided by the modern Bosch Performance Line CX motor, delivering up to 120 Nm of torque. This powerful mid-drive unit provides dynamic and natural assistance, particularly on steep climbs, against headwinds, and when carrying additional luggage. Thanks to the Bosch Smart System, assistance settings can be individually customised while modern connectivity features are also available. The Bosch LED Remote provides convenient control, while the large Bosch Kiox 500 display clearly presents essential riding information. This makes the E-Triton equally suitable for daily commuting and demanding touring adventures.
The Stevens E-Triton 9.9.1 Forma features a fully integrated Bosch PowerTube 600 battery with a capacity of 600 Wh. This comparatively lightweight battery blends seamlessly into the carbon frame and contributes to the bike's balanced overall weight. A particularly practical feature is the Bosch PowerMore 250 additional battery, which is already included as standard equipment. This compact additional battery provides another 250 Wh of capacity and can be mounted to the bike whenever required. Together, the batteries offer up to 850 Wh of total capacity. The PowerMore can be used flexibly, allowing riders to choose whether to ride with or without the additional battery depending on their needs. A Bosch 4A charger is also included.
One of the standout features of the Stevens E-Triton 9.9.1 Forma is its electronic Shimano CUES U8000 Di2 11-speed drivetrain. The Shimano CUES U8050 Di2 Shadow rear derailleur provides precise and convenient gear changes at the touch of a button. Compared to a mechanical drivetrain, electronic shifting eliminates traditional cable actuation, allowing particularly smooth and consistent gear changes. The Shimano CS-LG700 cassette offers a wide 11-50-tooth gear range, providing suitable gearing for steep climbs and faster sections. The durable Shimano LINKGLIDE chain is designed for high loads and extended service life, completing this premium electronic drivetrain.
Additional riding comfort is provided by the premium SR Suntour Auron36 Evo Boost EQ 2CR air suspension fork with 80 mm of travel. It effectively absorbs bumps and vibrations on uneven roads, cobblestones, and maintained forest or gravel paths, improving both comfort and front-wheel control. The air suspension can be individually adjusted to the rider's weight and offers responsive suspension performance. Combined with the comfortable carbon frame, it creates an enjoyable yet direct riding experience that is perfectly suited to versatile trekking applications.
The Stevens E-Triton 9.9.1 Forma is equipped with premium hydraulic Shimano CUES U8000 disc brakes. The powerful BR-U8020 brake calipers feature four pistons at both the front and rear, providing strong and precisely controlled braking performance. A large 203 mm front rotor and 180 mm rear rotor ensure dependable stopping power, even at higher speeds, on extended descents, or when carrying additional luggage. This makes the E-Triton well equipped for a wide variety of weather and riding conditions.
Premium DT Swiss H 1900 Spline wheels provide a robust and dependable foundation for daily riding and extended tours. They are paired with wide 50 mm Continental Pure Contact tyres, developed for comfortable and efficient riding on paved roads and maintained paths. The integrated PolyX Breaker puncture protection layer helps reduce the risk of punctures, while the generous tyre width provides excellent comfort across different surfaces. Reflective sidewalls further improve visibility in traffic. The 700 mm Scorpo Rise handlebar and comfortable Selle Royal Vivo Ergo Royal saddle complete the touring-oriented setup.
Another highlight of the Stevens E-Triton 9.9.1 Forma is its high-quality lighting system. The Busch+Müller Briq-M front light provides 150 lux low-beam illumination and a powerful high-beam function delivering up to 200 lux. This advanced lighting system ensures excellent visibility after dark and improves safety on unlit roads and cycle paths. At the rear, the Supernova TL 3 Z Pro rear light features an integrated brake light and standlight function for additional visibility. This premium lighting system is particularly beneficial for commuters and frequent riders who regularly travel in low-light conditions.
The Stevens E-Triton 9.9.1 Forma comes equipped with the Bosch ConnectModule as standard. In combination with the Bosch eBike Flow app and the relevant Flow+ services, it enables additional security features, including the Bosch eBike Alarm with visual and audible warnings and location tracking in the event of theft. The sturdy Racktime STV RC 13 rear carrier with SNAP IT 2.0 and Kid'n'Carry systems allows compatible bags and accessories to be attached conveniently and is designed to accommodate suitable child seats. A stable Stevens Edge kickstand and a bell complete the equipment. This makes the E-Triton an excellent choice for daily commuting and extended touring adventures alike.
The Stevens E-Triton 9.9.1 Forma is an excellent choice for riders seeking a premium electric trekking bike with an exceptionally low step-through frame and advanced technology. Its comfortable carbon construction combines effortless mounting and dismounting with sporty handling, while the powerful Bosch CX motor and electronic Shimano CUES Di2 drivetrain deliver a dynamic riding experience.
