E-STREAM EVO AM 4 27.5+

DESCRIPTION

What’s the point in having a bike that helps you go farther and makes you want to stay out all day if the battery isn’t up to the task? Welcome to the endurance steeds of the BULLS eMTB line-up. The all new, all-mountain E-Stream EVO AM series boast the new Brose Drive S Mag motor, smaller and lighter than the previous generation, with even more power and torque. But, what really sets this eMTB apart is the BULLS Supercore battery- 1 battery. 750Wh. That’s and optimal range of over 150 miles. As if that weren’t enough, both models are complete with Fox Float Rhythm 150mm front and rear suspension.

Check out the E-STREAM EVO AM 4 27.5+ (with Brose Drive S mag ) at a dealer near you!

If you've never heard of Bull bikes, you're not alone. Some of our testers had never seen or heard of them until the day they started riding our test model. The E-Stream EVO AM 4 we tested comes nicely equipped with a beefy enduro-ready build with 150mm of front and rear wheel travel, a stout RockShox Lyrik fork, and relatively modern geometry numbers. Wide rims and grippy 2.8 Schwalbe rubber help to maintain traction and tear through corners. This bike really comes to life at speed with a calm, stable, and confidence inspiring demeanor that begs to be ridden fast, although testers found it be a bit sluggish at lower speeds. The Brose motor system provides lots of smooth power with 4 customizable support settings and user-friendly controls. It also has a massive 650Wh battery that gives the bike a huge distance range, though it adds a bit of weight to this beefy rig. Overall, testers were impressed with the E-Stream EVO AM 4 and we awarded it with our Top Pick for Range and Battery Life. Read the full review.

Specifications subject to change without notice.

technology-image Smaller and lighter (just over 6lbs) than the current Drive S and with even more power (assist up to 410%) and torque (90nm), it is the most efficient and best performing motor for eMTB in the market.
technology-image With SuperCore of 750wh battery, you will never run out of juice while having fun! The battery can be removed and charged externally or installed in the bike.
technology-image The 11-speed drivetrain with 11-gear cassette has proved to improve efficiency and ultimately power
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 The travel of front suspension is 150mm.
technology-image Full suspension bike with a rear shock of 150mm travel.
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 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.
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.
