Men's ONE-Largo 7.7-S 2022 mountain e-bike with 29 wheels and a powerful battery that's worth it! Developed specifically for trips through the countryside, off-road, on the flats, over hills and for wandering in places you may not have ventured before.
The geometry of the aluminium frame ensures excellent stability, handling and reliability of the e-bike, which is mainly due to the central electric motor BAFANG MAX drive (M400), with a nominal power of 250W (max 500W), with a torque of 80 Nm and a battery with Li-Ion cells Panasonic 630 Wh (17.5 Ah), which is fully integrated into the frame of the e-bike.
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 ONE-Largo 7.7-S is a very practical and functional e-bike with a modern and attractive design.
The e-bike is produced on 29" wheels, which are now a necessary standard for mountain bikes, and in 18" and 20" frame sizes. Shifting is handled by a 9-speed Shimano Alivio or SRAM X5 derailleur and riding comfort is enhanced by Shimano BR-MT200 or SRAM Level hydraulic disc brakes, the Suntour XCM HLO DS 29" suspension fork is spring damped and has a travel of 100 mm. The wheels are shod with MAXXIS ARDENT 29 X 2.40 bike tyres, and provide excellent grip for the e-bike in the terrain.
The ONE-Largo 7.7-S is supplied without mudguards, lighting, stand etc. However, these can be easily purchased and subsequently fitted to the bike. On the other hand, a USB connector for charging mobile devices is included
The ONE-Largo 7.7-S mountain bike is designed for off-road riding, but it can also handle the road or cycle path without any problems. It's up to you. It differs from the e-Largo 7.7-S in design and offers a subtle colour combination.
Pedal on, the Crussis ONE-Largo 7.7-S is ready to go with you!
Should you desire a model with a more colourful design or better optional equipment (fork, derailleur...), the e-Largo 7.7-S/M/L, e-Largo 8.7-S/M/L or e-Largo 9.7-S/M/L e-bikes are available, which also has a better Bafang M500 motor.
