Elegantly integrated design, conquers any climb with minimum effort
If you are looking for the battery on the new BULLS E-Stream models you will have to inspect it closely. The E-STREAM has been designed with a downtube that neatly tucks away the battery. This uncompromising frame features a mid-engine, which ensures a better center of gravity. A second look at the endurance values prove that this detailed masterpiece does not pose any technical disadvantages.
With a 37V, 490 watt-hour battery the E-Stream FS Enduro is one of the strongest on the market. With the E-STREAM models you can always expect a smoother e-biking experience thanks to special sensor technology on the all new Brose drivetrains. Brose motors are based on a steering motor that has been produced a million times for the car industry and perfected a drive concept for high-quality eBikes. Nearly soundless and vibration-free, the motor produced entirely in Germany delivers nothing but strength and smooth operation. The Brose drivetrains are all designed to supply a perfect pedal assist support, harmoniously and powerfully.
The bike is built with a RockShox Pike RCT3 fork that offers 160mm of travel. Rear suspension duties are handled by a 3-position compression adjustment RockShox Monarch Plus. Hydraulic Shimano Saint Brakes with Ice Technology assure your pads and rotors stay cool to provide efficient braking in even the most extreme conditions. Three modes are available for the pedal assist and can easily switched to adapt to the type of riding you are doing whether it is long distance commuting or off-road adventuring.
Come check out why the BULLS eBIKES are Germany’s best-selling eBikes at a dealer near you.

I don't see many reviews of this bike but this bike is definitely underrated and very pleasing aesthetically than any other ebike in the market .I finally take delivery of this beautifully integrated Bulls Enduro.One thing I want to add into Court's detailed review is the Boost rear wheel, not the front wheel. It's good that you can use wider tires, not so if you want to upgrade to a light wheel ,which can cost for this mismatch (Boost). From my view point, it confirms very much like with Court.
Fortunately, I am able to bring it down to 46Lb and once I get hold of a rear boost crossmax elite wheel it will be even less.One last comment on Brose motor vs Yamaha and Bosch is refinement .Brose wins, however Bosch motor is very reliable at this point (1 year of rough trail use ).Also I notice on a tec-jump, once airborn for a few sec of freewheel, it seems that it can fool the bike sensor and the motor will power up and down (assist) slightly. However, it returns to normal after a few seconds. Just need to hold on your Saint brake. We'll see for a few more rides.
- Very quiet as I took it to the trail up and down right next to other cyclist. No noe has take any notice, unlike the Haibike FS xduro I had for a year, and still running trail very well, however, every other cyclist (front and back) noticed that was an electric bike because they could hear the hi winding motor sound), even if I peddle with the matching gear.As for the BULLS there is a sweat, quiet gear that matches the right environment, you do not hear any noise at all! You only feel the,smooth power.
- The 3 level assist is a good thing. I find out through out the entire trial ride as I set it 2nd level and I can ride the entire course climb up and down. I just simply shifted and changed gear without worrying about changing power level and still made through some very steep slope. This is not true with the Haibike with Borsch motor which I have to change power level more time to adjust to right cadence. It makes too much noise, and not enough assist. I think that is where the 90N kicks in, and the delivery is very smoothly.
- Non removable battery could have 2 good things. I have driven to the trail so many times and then realized I had forgotten my battery! It cuts my riding short. As battery I suppose you need to treat it like your indoor pet. Having a non-removable battery, there is one less thing to setup and worry about that may be damaged or knocked off when you crash, which happens to me so often and sometimes I even broke the brake lever and pedals.
- The spec comes with the bike is amazing. For example, the E13 chainguide is very special - you can remove your chain if it's jammed.

|
Quiet 250W motor with 90Nm of torque is claimed the most advanced ebike system in the world. |
|
An upgrade from the 9-speed predecessor. It permits a more gradual gear adjustment and more efficient force transmission. |
|
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. |
|
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. |
|
At 148mm, the rear hub of the boost standard is wider than any conventional one. Connected to the flatted spoke screen, it increases stiffness and stability of the wheel for even better handling. |
|
Tubeless clearly decreases rolling resistance of the wheels while reducing the overall weight of the bicycle. In addition, there is some extra grip and comfort when riding at a low pressure. |
|
Sandwich construction and additional cooling fins reduce the heat development and increases the brake performance and results in lower wear. |
|
Internally routed shifting and braking cables ensure a clean and elegant look while ensuring a better protection to all important cables |
