Description
CRUSSIS e-Hard 11.11-M2S(800)
A modern and powerful hardtail designed for athletic and experienced riders. The Avinox M2S motor is one of the most powerful on the market—it delivers high torque, very smooth and quiet assistance, and powerful acceleration even on steep climbs. The 800 Wh battery is elegantly integrated into the frame (low center of gravity) and enables long, all-day rides. The specs are significantly higher than those of standard Crussis models: a FOX AWL 34 fork with 130 mm of travel, more powerful SRAM DB8 brakes with 200 mm rotors, a modern SRAM Eagle T-Type drivetrain, and a dropper seatpost.
A New Standard of Quality for Aluminum Frames
The CRUSSIS MY27 sets a new standard for the quality of aluminum e-bike frames, where premium craftsmanship is the norm. Precisely ground welds, clean lines, and a look that’s almost carbon-fiber-like. The result is a combination of premium design, high strength, and durability that takes expectations for a modern e-bike to a whole new level. Because this is exactly what the standard for a high-quality e-bike should look like today.
SRAM DB8 Stealth – Front/Rear Hydraulic Disc Brakes
A high-performance hydraulic braking system designed for electric mountain bikes. The four-piston calipers provide reliable braking power and good control when riding on rough terrain. Thanks to the Stealth design, the hose routing is elegantly integrated along the handlebars. The brakes use Maxima mineral oil and are easy to maintain. The ergonomic brake lever allows you to adjust the distance from the handlebars, so you can customize its position to suit your needs. Compatible with SRAM Post Mount adapters.
AVINOX 12A Fast Charger
Thanks to GaN technology, it achieves a charging power of up to 508 W, significantly reducing the time needed to recharge. It can charge an 800 Wh Avinox battery from 0 to 75% in approximately 1.5 hours. Despite its high performance, it remains compact and easily portable, making it a practical accessory not only for charging at home but also for longer trips, training sessions, or multi-day travels. Dimensions: approximately 185 × 75 × 37 mm. Weight: approximately 985 g. A power cord is included in the package.
CRUSSIS e-Hard 11.11-M2S(800) – a powerful electric mountain bike with the Avinox M2S
A modern electric mountain bike from the 2027 collection that combines an aluminum frame, 29" wheels, and a powerful Avinox M2S drive system. Thanks to its high-capacity 800Wh battery, high-quality RockShox suspension, and SRAM components, it’s ready for long rides, steep climbs, and more challenging off-road riding.
Avinox M2S Motor – Up to 150 Nm
At the heart of the e-bike is the Avinox M2S mid-drive motor, which provides significant assistance when riding uphill and on technical terrain. In Boost mode, the system delivers up to 150 Nm of torque, allowing it to handle steep climbs and challenging sections with ease. The system is controlled via the 2" Avinox DPC100 OLED touchscreen, which displays ride data, assistance settings, and other system functions. Another practical feature is the USB-C port for charging compatible electronic devices.
Avinox 800 Wh Battery
A major advantage of this model is the removable Avinox battery with a capacity of 800 Wh. Its high capacity provides ample power for long trips and demanding routes in hilly terrain. The stated range depends on the specific configuration and riding conditions, and the actual distance per charge is influenced by the selected assist mode, route profile, terrain, rider weight, temperature, and other factors.
The package includes a 12A Avinox fast charger, which allows for quick recharging and reduces the time needed to charge the battery.
RockShox – Suspension for Off-Road Riding
For a comfortable and confident ride off-road, the e-bike is equipped with a RockShox air fork, which effectively absorbs bumps and helps keep the front wheel in contact with the ground. Thanks to its air suspension design, the suspension can be adjusted according to the rider’s weight and preferences.
29" Wheels and Off-Road Tires
The large 29" wheels contribute to stability and make it easier to navigate over roots, rocks, and other obstacles. Wider off-road tires provide plenty of traction when riding on forest trails, gravel, and more technical terrain.
SRAM Eagle 1×12
Shifting is handled by the SRAM Eagle 1×12, which offers a wide range of gears for a variety of trail types. The single-chainring design provides simple operation and allows for quick responses to changes in gradient. The wide cassette range makes climbs easier while also offering enough gears for a brisk ride on flat terrain and paved roads.
Powerful Hydraulic Brakes
Hydraulic disc brakes ensure safe deceleration, providing a smooth lever feel and ample braking power when riding on challenging terrain. You’ll especially appreciate these powerful brakes on steep descents, technical sections, and longer rides in hilly terrain.
Sturdy aluminum frame
The model is built around an aluminum frame that offers a good balance of stiffness, durability, and weight. The design is built for off-road use and, together with the large 29" wheels, creates a stable foundation for confident riding.
The CRUSSIS e-Hard 11.11-M2S(800) is an electric mountain bike for riders who want to combine the modern Avinox drive with a high-capacity battery and high-quality off-road components. The powerful Avinox M2S motor, 800Wh battery, 29" wheels, RockShox suspension, and wide gear range create a versatile foundation for long rides, steep climbs, and adventures on more challenging terrain.

Avinox M2S
A high-performance motor with 130 Nm of torque (150 Nm in Boost mode), a peak power output of 1500 W (with the FP700 battery; 1,300 W with other batteries; or 1,500 W in Boost mode with the RS800) and a lightweight design (2.59 kg). The second generation features flat-wire winding for higher efficiency, quiet helical gearing, and Dual Gear Engagement technology, which eliminates rattling during descents without assistance. Internal resistance has been reduced by 41%, ensuring a natural ride even with a depleted battery. Integrated sensors enable adaptive power control based on cadence and riding conditions. Intelligent electronics ensure lightning-fast pedal response and smooth power delivery that will support you even on the most demanding terrain.
Avinox RS800 Battery
The Avinox RS800 battery, with a high capacity of 800 Wh, combines maximum power with the practicality of a removable system. Weighing 4.0 kg and featuring IP56 protection, it can be easily removed from the frame thanks to a locking mechanism and charged anywhere away from the bike. It delivers an impressive continuous power output of 1300 W and can reach a peak of 1500 W in Boost mode. Intelligent health management ensures 80% capacity retention after 500 cycles, and GaN technology enables ultra-fast charging.
Display Avinox DP100
