Getting ready to purchase, could not find any reviews of the bike, other than the German "Zebra Project" version. Theory here is obtaining the benefits of the 29er while letting the massive battery and engine torque take care of the extra energy required for the larger wheels. I wonder if EBR will review this model?

BTW: If you go to the Bulls international site for Germany, you will notice the bikes being sold there, across all model ranges, are just BETTER than the USA versions, plus most come with the Brose full display/controller. No fun trying to import one I am guessing (?)

Did you end up getting this bike? How do you like it? Any update or review?

In my personal opinion, this is one of the sleekest and great looking/performing 29er. Perfect for single tracks. I rode this back in 2016 for about 100 miles off-road and was impressed.

When I googled, there were some scattered reviews for this product. This is from someone else, not me.

Very few times does a product over deliver this much!

Background: I built a 3D printed kepler drive roadbike and climbed mt. washington with it. Great for a road bike, but not a sophisticated enough control system for technical single track riding.

The riding I do is very rocky, see a video of me at my local trail here: [youtube]https://youtu.be/4ZLbgR_U-Ng?t=57s[/youtube] , which means a bafang or TZ mid drive kit would be smashed on the first ride.

My criteria for a new E-bike was as follows -Performance off road (good suspension, drivetrain, BB clearance etc.) -Torque sensing, natural riding experience -Intergrated design -Low noise -Range

I ended up selecting the Bull E-stream evo 29er FS http://(Link Removed - No Longer Exists) as it looked to have all the features I needed. Can't recommend the dealer in Madison enough!

I have 5 hours of single track riding here in new england so far, so here are my first impressions. Imgur

First the riding experience of the Brose motor system is exactly what I was looking for. It is silent, and reacts so quickly to my pedal inputs that I never am search for power when I need it, or pushed through a corner or obstacle when I don't want to be. The 650Whr battery is really over kill for most of my rides, as I can finish up a 1.5hr single track ride and still have 4 out of 5 bars left over. I can't wait to go for a longer all day ride and see how it performs. Almost all of my riding is done at level 2 of 4 assist, as this feels most natural and controllable in the woods. Riding roads or double track is the only place where the top assist is helpful, which allows a 19mph pace with very little effort on the riders part. The other (non)noticeable feature of the brose is the lack of noise, really silent in level 2, and even level 4 is hardly noticeable unless I am climbing out of the saddle. The lack of noise and integrated design really make it a stealthy Ebike.

The only part of the bike I would change is the weight. It only apparent when trying to loft the wheel over rocks, or hopping off features. I am excited to try a bike with the lightweight Fazua drive, as it should have enough power and range for me, while weighing less.

Overall I can't see the point in DIY at this time if you are looking for a natural riding experience in technical single track. For the price you can't source a non-powered bike of this level, a mid drive kit, and a battery.
