Description
A powerful, upper-mid-range women's electric mountain bike. The Avinox M2S motor delivers high torque and very smooth, quiet assistance—making it ideal for climbs and more technical terrain. The smaller 600Wh battery keeps the weight at an acceptable level while still providing sufficient range for most rides. The specs are solid for trail riding: a 120 mm RockShox air fork, SRAM DB4 4-piston brakes, a modern 12-speed SRAM Eagle T-Type drivetrain, and 29" wheels with versatile Schwalbe tires. The frame features geometry tailored for women to ensure a more comfortable riding position.


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.
ROCKSHOX FS Recon Silver RL Solo Air 29" BOOST 120 mm
An air-sprung fork for 29" electric mountain bikes that combines low weight, easy adjustment, and reliable off-road performance. Thanks to the Solo Air system, air pressure can be easily adjusted to the rider’s weight and riding style. It features 120 mm of travel and a robust design with a Boost 15×110 mm hub. The Solo Air suspension ensures comfort and control over the bike. Motion Control damping allows you to adjust compression and tailor the fork’s behavior to specific conditions.

CRUSSIS ONE-Fionna AX 9.12-M2S(600) – Women's Mountain E-Bike with Avinox M2S
It combines an aluminum frame, large 29" wheels, and a powerful Avinox M2S drive. Thanks to its 600Wh battery, high-quality RockShox suspension, and SRAM components, it’s ready for brisk rides, steeper climbs, and riding on more challenging terrain.
Avinox M2S Motor – Up to 150 Nm
At the heart of this e-bike is the Avinox M2S mid-drive motor, which delivers high torque and significant assistance when riding uphill and on technical terrain. In Boost mode, the system delivers up to 150 Nm, allowing you to easily tackle even steep climbs and challenging sections. The system is controlled via the 2" Avinox DPC100 OLED touchscreen, which displays ride data, assistance mode, and other system functions. Another practical feature is the USB-C port for charging compatible electronic devices.
Avinox 600 Wh Battery
The motor is powered by a removable Avinox battery with a capacity of 600 Wh. It offers enough power for longer rides and all-day off-road excursions. The stated range is up to 117 km, though the actual distance per charge depends on the selected assist mode, route profile, terrain, rider weight, temperature, and other conditions.
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, thanks to its lockout feature, can also be adjusted for riding on smoother sections.
29" wheels and Schwalbe Smart Sam tires
The large 29" wheels provide stability and make it easier to navigate over roots, rocks, and other obstacles. Traction is provided by Schwalbe Smart Sam Performance 29 × 2.60" tires, which combine reliable grip on rough terrain with good rolling efficiency on paved roads.
SRAM S100 Eagle 1×12
Shifting is handled by the SRAM S100 Eagle 1×12. The 11–50-tooth cassette offers sufficient range for steep climbs and faster riding on flat sections. The single-chainring setup provides simple operation and allows you to 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. They provide ample braking power and control when riding uphill, on technical sections, and during longer descents.
Women’s Aluminum Frame
The bike is built around an Alu 6061 aluminum frame, designed for comfortable and confident handling of the e-bike. Solid BOOST axles contribute to the high stiffness of the entire structure and ensure stable handling of the bike off-road. The CRUSSIS handlebars are 740 mm wide and help provide precise control when riding off-road.
This e-bike is designed for riders looking for a modern mountain e-bike with a powerful Avinox drive, high-quality suspension, and components ready for more challenging terrain.
The CRUSSIS ONE-Fionna AX 9.12-M2S(600) is a women’s mountain e-bike for riders who want to combine modern Avinox technology with confident handling and high-quality off-road equipment.
