Xtreme 8.5
The MTF Xtreme 8.5 is a full-suspension SUV e-bike that blends the agility of a mountain bike with the comfort and utility of a touring model. With 29” wheels, wide Maxxis Forekaster 2.4” tires, and a powerful Bafang M510 mid-drive motor, it's built for both off-road trails and long-distance rides. Integrated fenders, a rear rack, and advanced suspension ensure maximum comfort and control wherever you ride.

The MTF Xtreme 8.5 is a premium full-suspension SUV e-bike that merges the versatility of a mountain bike with the features of a touring model, making it ideal for both rugged off-road terrain and extended bike path adventures. Designed with a mountain bike geometry, integrated fenders, a rear carrier, and wide Maxxis Forekaster 29.5 x 2.4" tires on 29" wheels, it offers a perfect balance between performance and practicality.
At its core is the powerful Bafang M510 mid-drive motor with a pressure sensor – currently the most powerful in its class. Delivering up to 95 Nm of torque and 750 W of peak output, it ensures smooth and efficient power, whether you're climbing steep hills or cruising on pavement.
This model is equipped with high-end components to tackle tough conditions. A Shimano CUES 11-speed shifter and CUES RD-U6000GS derailleur provide precise shifting, while the SR Suntour XCR BOOST AIR fork with 140 mm travel and the RAIDON LO AIR rear shock (190 x 51 mm) offer excellent suspension performance. Shimano BR-MT410 hydraulic disc brakes deliver dependable stopping power even on challenging descents, and the drivetrain is complemented by a Shimano CUES 11-speed cassette (11–50T) and Shimano chain (CN-LG500).

All riding data, assistance levels (5 modes), and battery status are clearly displayed on a color smart LCD with Bluetooth and GPS capabilities.
