Description

Pushing the boundaries of trail cycling, the Mountain E-Bike 4EVER Exstream PRO 820Wh boasts a lightweight yet strong aluminum frame that offers the perfect balance between durability and comfort. With its sleek design and integrated battery, the bike looks elegant and aerodynamic, while the frame geometry ensures an ideal riding position for both long-distance trips and technical descents. The high-capacity, 820Wh battery by BMZ can take you up to 160 km on a single charge. Whether you’re hitting mountain trails or exploring hidden paths, the Exstream PRO e-bike is your reliable companion.

Powerful Motor for Challenging Terrain

At the heart of this machine is the top-tier BROSE Drive S-Mag motor, delivering 90 Nm of torque for smooth and natural pedal assistance. The motor is exceptionally quiet and incredibly lightweight, thanks to its magnesium alloy construction. You can count on instant response during climbs, brisk acceleration on flat terrain, and confidence in technical sections.

High-Capacity Battery and Premium Display

Need energy? No problem! Made in Germany, the integrated BMZ V10 battery with a capacity of 820 Wh can take you up to 160 km on a single charge. You can recharge it directly on the bike or remove it for charging elsewhere. Whether you’re planning an all-day ride or a weekend adventure, you won’t have to worry about running out of power.

Everything is under control thanks to the modern, sunlight-readable BROSE Allround display with Bluetooth connectivity. It clearly and intuitively shows battery status, speed, and distance traveled – all within easy reach.

Suspension for a Comfortable Ride

What about comfort on the road? That’s handled by the ROCK SHOX JUDY GOLD suspension fork with 120 mm of travel, capable of tackling roots, rocks, and trail bumps. The fork offers stiffness adjustment and a lockout feature, allowing you to tailor the bike to your terrain. Add the wide SCHWALBE Smart Sam tires and reliable SHIMANO BR-M6100 disc brakes, and you can rest assured that your ride will be not only fast, but also safe and comfortable.

Hop on, start pedaling, and see how far the Exstream PRO e-bike can take you!

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.

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.
