Recommended accessories


The Mountain E-Bike Crussis ONE-Guera 7.9-M – 2024 is a well-equipped monochromatic women’s mountain e-bike. Part of the legendary 7-Series, this model boasts an outstanding geometry with a lowered frame tube, which makes it easy to control and suitable for both paved/forest roads and challenging terrain. The Panasonic GX Power Plus drive and fully-integrated, 20Ah LG battery make it perfectly balanced. Furthermore, the high-capacity battery allows for a distance range of up to 170 km depending on the terrain). You can choose one of the 5 available assistance modes on the color LCD screen, where there is also a USB port which allows you to charge your mobile device.

The Mountain E-Bike Crussis ONE-Guera 7.9-M – 2024 features 27.5” wheels and high-quality Maxxis Ardent tires that provide excellent adhesion on all surfaces. The hydraulic disc brakes and Suntour XCM32 NLO DS coil suspension fork with 100mm travel allow for a safe and comfortable ride. A pleasure to ride, the Mountain E-Bike Crussis ONE-Guera 7.9-M – 2024 is so good that nothing’s going to stop you.

Adjustable Fork

The Mountain E-Bike Crussis ONE-Guera 7.9-M – 2024 features a SUNTOUR XCM32 NLO DS 27.5” spring suspension fork with 100mm 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 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). 

Powerful PANASONIC Drive

The PANASONIC GX Power Plus is a reliable drive for riders who need more assistance, especially while riding on a challenging terrain. It’s ideal for sports and trekking bikes as it offers outstanding performance even on forest or gravel roads. The drive offers a torque of 75 Nm, features a torsional pedaling force sensor, and weighs only 3.2 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.

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.

There is no established standard for weighing e-bikes. Some manufacturers say their bikes are lighter than they actually are. If you want to know how heavy the bike is, you’ll need to have it weighed at the store.

Weight limit

120 kg

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.
