The e-Fionna 7.8-S 2023 women's mountain e-bike has been developed for trips through the countryside, off-road, on the flats, over hills and wandering in the mountains. Thanks to its comfortable geometry, the aluminium frame is fully adapted to women's needs. The frame geometry ensures excellent stability, handling and controllability of the e-bike, which is mainly taken care of by the BAFANG MAX drive (M400) central electric motor, rated at 250W (max 500W), with a torque of 80 Nm and a powerful battery with Panasonic 630 Wh (17.5 Ah) Li-Ion cells, which is fully integrated into the e-bike frame.
The use of a central electric motor in this model contributes greatly to the ideal balance of the e-bike - a modern solution used in higher-end e-bike ranges around the world. The range of the e-bike is up to 150 km - of course, it always depends on the profile of the track and how the assistance is used, which in the case of this model is five-speed and controlled via an LCD display located on the handlebars. The colour display shows the battery level, the selected level of electric motor assistance, speed and distance travelled. The Crussis e-Fionna 7.8-S is a practical and highly functional e-bike with a timeless design.
The e-bike is produced on 29" wheels, which are now a necessary standard for mountain bikes, and in 17" and 19" frame sizes. Shimano Alivio or SRAM X5 9-speed derailleur takes care of shifting, while Shimano BR-MT200 or SRAM Level hydraulic disc brakes and Suntour XCM HLO DS 29" suspension fork are equipped with spring damping and have a travel of 100 mm. The wheels are shod with MAXXIS ARDENT 29 X 2.40 bike tyres, which perfectly ensure the grip of the e-bike in the terrain.
The e-Fionna 7.8-S model is supplied without mudguards, lighting, stand etc. However, these can be easily purchased and subsequently mounted. On the other hand, a USB connector for charging mobile devices is included. The e-Fionna 7.8-S women's mountain e-bike is designed for off-road riding, but can also handle the road or cycle path. It differs from the e-Guera 7.8-S in wheel size and comes on 29" wheels.
