With the consistent merging of the latest drive technology and an exclusive setting design, the E-STREAM series creates an eBike experience with a maximum sporting factor. The most powerful battery, fully-integrated in the downtube, is on the market with the Brose BULLS co-designed engine for a new development stage in the EVOlution of eBikes. The E-STREAM EVO models are classic bikes with a little extra push, whether you’re pedaling on or off-road, they open up new perspectives.

The latest 50-cell battery technology gives the removable battery an impressive capacity of 650 watt-hours in the blink of an eye. Combined with the equally powerful and energy-efficient Brose Drive S (250W), the E-STREAM EVO series works to true condition miracles. Thanks to 100 Nm of torque you’ll never be lacking the power to get the necessary “punch.” The belt driven motor pedals with ultimate smoothness and thanks to the high-resolution sensors, it’s always assisting efficiently.
The combination of strength and stamina to create a perfect center of gravity while still maintaining an optimal ground clearance wasn’t easy. Much engineering and testing went into the creation of our E-STREAM EVO series. Integration was key for simplicity and our CSI display is the perfect example for that. The combined capability of control and information is easily managed in our Compact Sports Interface display. The CSI display is conveniently located on your handlebars where it provides necessary information and controls. The unit isn’t bulky so during a fall or crash it isn’t prone to breaking.

With so much attention to detail, other features such as the new Boost hub standard for increased wheel rigidity, a Rock Shox Yari RC Boost Solo Air, 150mm, E-thru and a Rock Shox Deluxe RT, 150mm. Shimano Deore RD-M6000-GS, and extra-wide tires for increased traction all make the BULLS E-STREAM EVO AM 3 27.5+ a solid choice. Unlike most eBikes on the market, our integrated battery allows space to accommodate a water bottle cage for hydration.

In addition to a sophisticated interplay of technology and design the E-STREAM EVO series has a stellar range of models. The models range from all-mountain, full-suspension bikes for technical trails or marathon use to hybrids and even fat bikes. The redesigned frame on our Plus models allows for more tire clearance allowing you to use plus size tires for maximum traction. Wider tires also absorb more bumps on the road essentially giving you a more comfortable ride.

Not to mention that E-STREAM EVO AM 4 is MonkeyLink compatible, you  can easily add the accessories such as rear light, front light, water bottle, and mudguards in just one-click.

Specifications subject to change without notice.

technology-image Quiet Brose Drive S (250W) motor with 90Nm of torque is claimed the most advanced ebike system in the world.
technology-image The battery can be removed and charged externally or installed in the bike.
technology-image The 10-speed drivetrain with 10-gear cassette has proved to improve efficiency.
technology-image Perfectly integrated into the frame and easy to remove for external charging, it is currently the highest performing rechargeable battery in the market with 650w/37V/17Ah.
technology-image This is semi-integrated headset with an inner diameter of 1 1/8" at the top and 1.5" at the bottom. This ensures best riding stability and excellent control head stiffness. The biggest shaft results in stiffer fork and frame as riding forces are spread more evenly thanks to a thicker head tube.
technology-image Shimano Shadow Plus clutch mechanism prevents the lower arm of the derailleur from pivoting forward as the chain is kept under considerably more tension. The benefits are many: less chain slap, fewer dropped chains, more stable and accurate shifting over rough terrain and ultimately a much better and quieter ride.
technology-image The main advantages of the thru-axle system are stiffness and strength, which add together to a safer bike. It has a clear advantage on disc brakes over the traditional quick release as it allows for easier and more precise wheel mount/dismount operation.
technology-image At 110mm/148mm, the hubs of the boost standard are wider than any conventional ones. Connected to the flatted spoke screen, they increase stiffness and stability of the wheel for even better handling.
technology-image Internally routed shifting and braking cables ensure a clean and elegant look while ensuring a better protection to all important cables
technology-image Higher frames require longer chainstays. The result is a much-improved climbing capacity, which is relevant in large frames. After all, the center of gravity clearly shifts backwards with a taller rider, specifically during the climb. Taller riders also need more space as they usually have longer feet and for the longer cranks to avoid touching the chainstays with their heels.
technology-image The travel of front suspension is 150mm.
technology-image Full suspension bike with a rear shock of 150mm travel.
technology-image The standard feature on the all new BULLS eMTB fully that allows the rider to descend safer with better position without being penalized by the weight. rnrn
technology-image MonkeyLink compatible - the magnetic mechanism allows the riders to add accessories in one-click. This model MonkeyLink compatible, easy to install MonkeyLink rear light, front light,and mudguards.
