Description
CRUSSIS e-Hard 11.11-PRO-M2S(800)
A top-of-the-line trail hardtail for demanding riders. The Avinox M2S motor is among the absolute best—it delivers extreme torque, very smooth operation, and maximum power in Boost mode. The large 800Wh battery allows for all-day rides even on challenging terrain. Compared to the base e-Hard 11.11 model, the PRO version offers significantly higher-end components: a FOX 36 Factory fork with Kashima coating and Grip X2 damping (140 mm), SRAM GX Eagle AXS wireless electronic shifting, and more powerful brakes. The geometry and components are geared toward more aggressive trail riding and lighter enduro.
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.
FOX Float 36, Factory Grip X2, 29", 140 mm travel
A top-of-the-line fork designed for demanding terrain, where it excels thanks to its strength, precision, and extensive tuning options. Massive 36mm inner legs ensure high stiffness and precise tracking, while the new GRIP X2 damping system offers four-way adjustment with an emphasis on maximum traction, stability, and control in technical sections. The EVOL air cartridge increases the fork’s sensitivity over small bumps while promoting progressive response during larger impacts. Of course, it features a 15x110 mm thru-axle, a 1.5" tapered steerer tube, and an integrated FOX mudguard that protects both the fork’s internals and the rider when riding in mud and wet conditions.
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-PRO-M2S(800) – a powerful hardtail with an Avinox M2S drive
A sporty electric mountain bike that combines a lightweight and sturdy aluminum frame with a powerful Avinox M2S drive, a high-capacity battery, and components designed for demanding off-road riding. Large 29" wheels, a FOX Float air fork, and a dropper seatpost provide stability, comfort, and confidence when riding on forest roads, rocky trails, and steep descents.
Avinox M2S Motor – Up to 150 Nm
At the heart of the e-bike is the Avinox M2S mid-drive motor with 130 Nm of torque, which can deliver up to 150 Nm in Boost mode. Peak power reaches up to 1,500 W, so the motor provides significant assistance on steep climbs and technical ascents. Thanks to smooth assistance control, the motor’s performance can be adapted to current conditions and riding style.
The system is controlled via the 2" Avinox DP100 OLED touchscreen display. It clearly displays important riding data and allows you to adjust individual drive functions. Another practical feature is the USB-C port for charging compatible devices.
Avinox 800 Wh Battery
Power is supplied by an integrated Avinox battery with a capacity of 800 Wh. This large capacity is ideal for long mountain rides and challenging routes where motor assistance is needed for extended periods. The battery is removable, and the package includes a 12A charger for fast recharging.
FOX Float 36, Factory Grip X2, 29", 140 mm travel
The front of the bike features an air-sprung FOX FLOAT 36, Factory Grip X2 fork with 140 mm of travel. Its robust construction is designed for intense riding on challenging terrain while still responding sensitively to roots, rocks, and other obstacles. The fork contributes to better front-wheel control and confidence during faster downhill rides.
29" Wheels for Off-Road Stability
The CRUSSIS e-Hard 11.11-PRO-M2S(800) features 29" wheels, which make it easier to navigate uneven terrain and provide a stable ride. The wide CRUSSIS rims are paired with tires suitable for trail and mountain riding, providing the necessary traction on both climbs and descents.
SRAM GX Eagle AXS T-Type – precise 1×12 shifting
Shifting is handled by the SRAM Eagle Transmission electronic system with 12 speeds. The wide cassette range offers plenty of options for steep climbs and fast descents. The single-chainring setup simplifies control and lets you focus on the ride itself and choosing the right line.
Powerful SRAM DB8 Hydraulic Brakes
For safe deceleration, the e-bike is equipped with hydraulic disc brakes that deliver high braking power. The large rotors help you maintain control of the bike during longer descents and when braking hard on technical terrain.
Telescopic seatpost for better control
The bike comes equipped with a dropper seatpost, which allows you to quickly adjust the saddle height while riding. On descents, you can lower the saddle to gain more room for actively maneuvering the bike and shifting your center of gravity.
The CRUSSIS e-Hard 11.11-PRO-M2S(800) is an e-bike for riders looking for significant motor assistance, a large battery capacity, and components designed for sporty off-road riding. The Avinox M2S, with torque of up to 150 Nm, an 800 Wh battery, 140 mm of suspension travel, 29" wheels, and a modern SRAM Eagle Transmission system combine to form a powerful package for mountain rides, technical trails, and even the most challenging descents.
