Description
A high-performance electric mountain bike for demanding riders
It’s built on an aluminum frame characterized by clean lines, strength, and a modern design. The geometry is sporty, stable, and confident even on technical sections. The e-bike handles speed with confidence while remaining agile enough for off-road riding. At the heart of the e-bike is the Avinox M2 motor, which ranks among the most powerful drives in its category. It offers high torque, smooth assistance, and immediate response when pedaling. Thanks to this, it handles steep climbs, brisk acceleration, and challenging routes without hesitation.
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.

CRUSSIS e-Largo AX 9.12-M2(800) – a powerful mountain e-bike for demanding riders
A modern electric mountain bike that combines a sturdy aluminum frame, large 29" wheels, and a powerful Avinox M2 drive. With an 800Wh battery, high-quality RockShox suspension, and SRAM components, it’s ready for longer rides, steeper climbs, and off-road riding.
Avinox M2 motor – up to 125 Nm
At the heart of the e-bike is the Avinox M2 mid-drive motor, which delivers 110 Nm of torque and can briefly reach up to 125 Nm in Boost mode. The motor’s maximum power output is up to 1,100 W, providing significant assistance on climbs and when riding over rugged terrain.
The system is controlled via the 2" Avinox DPC100 OLED touchscreen display, along with wireless controllers. Another practical feature of the system is the USB-C port, which allows for fast charging of compatible electronic devices.
Avinox 800 Wh Battery
A major advantage of this model is the removable Avinox battery with a capacity of 800 Wh. It provides enough power for longer trips and more challenging routes. The stated range is up to 157 km, though the actual distance per charge depends on the selected assistance mode, route profile, terrain, rider weight, temperature, and other conditions. A 12A charger is included.
RockShox Recon Silver RL – 120 mm travel
For a comfortable and confident off-road ride, the bike is equipped with a RockShox Recon Silver RL Solo Air 29" BOOST air fork with 120 mm of travel. The fork effectively absorbs bumps, helps keep the front wheel in contact with the ground, and its lockout feature allows you to adjust the bike for riding on smoother sections.
29" wheels and Schwalbe Smart Sam tires
The large 29" wheels provide the e-bike with stability and make it easier to navigate over roots, rocks, and other uneven terrain. The CRUSSIS rims feature a double-wall construction and are 30 mm wide. Traction is provided by Schwalbe Smart Sam Performance 29 × 2.60" tires, which combine good off-road grip with a smooth ride on paved roads.
SRAM S100 Eagle 1×12
Shifting is handled by the SRAM S100 Eagle 1×12. The 11–50-tooth cassette offers a wide enough range for steep climbs and faster riding on flat terrain. The single-chainring setup makes shifting simple and lets you focus on the ride itself.
SRAM DB4 Four-Piston Brakes
Safe deceleration is ensured by SRAM DB4 hydraulic brakes with four-piston calipers and 180 mm rotors front and rear. This setup provides ample braking power and control when riding uphill, on technical sections, and during longer descents.
Rigid Aluminum Frame
The bike is built around an Alu 6061 aluminum frame, complemented by rigid BOOST axles—the front hub uses a 15 × 110 mm standard, while the rear uses 12 × 148 mm. The CRUSSIS handlebars are 740 mm wide and contribute to confident handling of the bike off-road. The e-bike is available in sizes S, M, L, and XL, and its maximum weight capacity is 120 kg.
The CRUSSIS e-Largo AX 9.12-M2(800) is a mountain e-bike for riders who want a combination of powerful drive, high-capacity battery, and confident handling on the trail.
