Women's e-Cross low 7.8-S 2023. Designed for sporty riding and trips of all kinds on roads and cycle paths. It can also handle sportier riding in light terrain. You no longer have to worry about the hilly profile of the trip, or that you might not be able to keep up with others. Thanks to its lowered aluminium frame, the e-bike is designed just for the ladies. The geometry of the frame ensures not only comfortable mounting and dismounting, but also great stability, handling and reliability. This is mainly ensured by the BAFANG MAX drive (M400) central electric motor, rated at 250W (max 500W), with a torque of 80 Nm and the extra strong battery with Panasonic 630 Wh (17.5 Ah) Li-Ion cells, which is fully integrated into the 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. A USB connector for charging mobile devices is included.
The e-bike is manufactured on 28" wheels in frame sizes 15", 17" and 19". Shifting is taken care of by a 9-speed Shimano Alivio or SRAM X5 derailleur and riding comfort is made more comfortable by Shimano BR-MT200 or SRAM Level hydraulic disc brakes, the Suntour NEX HLO DS 700c suspension fork is equipped with spring damping and has a travel of 63 mm. The e-Cross low 7.8-S comes without mudguards, lighting, kickstand and rack. However, these can be easily purchased and retrofitted to the e-bike. Alternatively, the e-Savela 7.8-S model is available with mudguards and rack.
The Crussis e-bike e-Cross low 7.8-S with central electric motor is ready for your awesome trip. Put the pedals down!
