Recommended accessories


The Mountain E-Bike Crussis e-Fionna 10.9-M – 2024 is a powerful e-bike with larger wheels! This model features an outstanding PANASONIC GX Ultimate drive that only weighs 2.95 kg and offers a high torque of 95 Nm while maintaining low battery consumption. The bike is powered by a fully-integrated, high-capacity, 20Ah LG Li-ion battery, which allows for a distance range of up to 170 km (depending on the terrain), and, along with the center drive, makes it perfectly balanced. This bike also boasts a slightly lowered frame tube and a 12-speed SRAM SX Eagle gear shifter. 

Most mountain bikes come with the large, 29” wheels. And the Mountain E-Bike Crussis e-Fionna 10.9-M – 2024 is no exception! Moreover, the high-quality Maxxis Ardent tires provide excellent adhesion on all surfaces. The hydraulic disc brakes and ROCKSHOX FS Recon Silver RL Solo Air suspension fork with 120mm travel allow for a safe and comfortable ride. The Mountain E-Bike Crussis e-Fionna 10.9-M – 2024 is a great bike for an unbridled terrain ride.

Ultra-Powerful PANASONIC Drive

The PANASONIC GX Ultimate is a sturdy, extremely powerful drive that can deal even with the most challenging uphill rides. Ideal for mountain bikes, the drive offers a torque of 95 Nm, features a torsional pedaling force sensor, and weighs only 2.95 kg.

Apart from battery status and current assistance mode, the easy-to-read LCD color screen also shows speed and distance covered. Apart from the three main assistance modes (HIGHSTANDARD and ECO), the bike also offers a dynamic AUTO mode, which adjusts the level of assistance to the initial torque of the rider. On the LCD screen, there’s also a USB port which allows you to charge your mobile device.

Air-Suspension Fork

The Mountain E-Bike Crussis e-Fionna 10.9-M – 2024 features a ROCKSHOX FS Recon Silver RL Solo Air 29” air suspension fork with 120mm travel, which adjusts to the user’s weight. All you have to do is adjust the spring tension and the e-bike will adapt to your weight and riding style. A well-adjusted fork absorbs shocks during terrain rides and does not provide too much suspension on a flat surface. Moreover, the fork can be locked out from the crown.

Powerful and Reliable Battery

The LG Li-ion 36V/20Ah (720Wh) high-capacity battery is the heart of the bike. The battery is fully integrated into the frame, making the bike (along with the center drive) well-balanced. The battery allows for a distance range of up to 170 km on a single charge (depending on the trail profile).

Top-Class Gear Shifter

SRAM Eagle technology allows for smooth and accurate shifting of gears, which you can rely on in every situation. Eagle is a revolutionary MTB technology as it features an ideal, single-chainring drive, which is lightweight, durable, easy to use (intuitive operation) and offers a variety of programs for all kinds of terrain.

The PG-1210 SX cassette is the only Eagle cassette designed to meet the ever-increasing demands on mountain bikes, making it perfect for challenging terrain riding. 

Battery storage and maintenance: We recommend storing the battery (or the entire product including the battery) in a shady, dry place at temperatures between 10 ° C and 20 ° C. If you do not intend to use the product for a long time, we recommend charging the battery and recharging it to 100% capacity at least once a month. Follow these guidelines to prevent the battery's nominal capacity from declining rapidly over its lifetime.

E-bikes CRUSSIS are assembled directly in the Czech Republic, under professional supervision and in cooperation with cycling experts. This progressive Czech brand guarantees quality, modern design and maximum enjoyment from the ride.

Warning: The factory setting for maximum speed is 25 km/h to meet the European standard for e-bikes. However, the setting can be manually changed to a higher speed limit. Bear in mind that in such a case the e-bike no longer meets the required standards and cannot be used on public roads!

Note: The expected max. travel distance depends on various factors, such as the amount of electric assistance, user weight, terrain, wind and the inflation pressure, pattern and temperature of the tires. All stated travel distances are valid under optimal conditions, meaning even terrain with no wind, temperature of 20°C, extremely narrow tires with no profile and user weight under 70 kg.
