Details

Torque, speed, and elegance were finely balanced in the making of the E-STREAM EVO 45 FS. Propelled by a light, compact, and extremely powerful BROSE motor you will receive pedal assist speeds up to 28mph. The battery is sophisticatedly integrated into the downtube giving your eBike a very discreet look. With the most powerful eBike battery on the market, you will be inspired to ride longer, harder, and faster. The bike is well equipped with a RockShox Pike RC fork matched with a RockShox Monarch RT shock in the back. The kinematics of the suspension was designed to help the rider pedal forward efficiently. The drivetrain is fitted with the newest Shimano Deore XT M8000 that has plenty of gear range allowing you to glide through any terrain.

 

 

technology-image Quiet 350W motor with 90Nm of torque and assists up to 28mph 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 One of the most important features of Brose system which allows double drive. Owing to the additional front chainwheel, a 22-speed gears permits a more sporty eBiking experience.
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 148mm, the rear hub of the boost standard is 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 The travel of front suspension is 150mm.
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.

Review

 

 

  • A high quality full suspension e-mountain bike that's also a speed pedelec (capable of 28 mph top speeds), solid hydraulic disc brakes, wide thru-axles with Boost Technology.
  • Adjustable 150 mm RockShox suspension front and rear, four-bar rear swing arm to reduce brake jack, 22 speed drivetrain with Shimano Deore XT Shadow Plus clutch on rear derailleur to reduce bounce and slap.

This bike is fantastic, being made with high quality parts like the RockShox suspension to the Shimano shifter and everything in between. The engine and the battery are phenomenal in this bike and It hard to explain in words the feeling you get from this set up. It puts other bikes to shame and its like your going down the mountain as you are pedaling up it. All and all this is a great built bike with high quality parts and the warrantee is unreal. I ride this bike almost every single day whether it be to work or up in the mountains and I have had no problems with it because of the build quality.

Great Ride, Powerful Ride
 

The specs on this e-mountain bike make this model particularly appealing: 650Wh battery means long journies; 350W Brose motor equals massive torque and fine speeds. I use the bike mainly as a trial bike and enjoy that I can get a good workout in the lowest assist mode, while maintaining the option to amp up the assist at will. I still ride my "regular" mountain bike, a very light-weight Trek Fuel EX, but the Bulls bike is a pleasure to ride too, though in a different way (the Trek is *very* agile). Owning an e-mountain bike allows me to ride more often, including "rest" days, which are needed when riding regularly and hard.
