After making us wait for a while, Shimano finally unveiled the EP8. The least we can say is that thanks to its technical characteristics and its design, this new benchmark from the Japanese firm does not have to be ashamed of the competition.
One thinks among others of its rivals from Bosch, Yamaha or BMZ. Evolution of the Steps e8000, the Shimano EP8 promises significant progress while keeping the main advantage of its predecessor, namely, a particularly smooth pedaling assistance.
Much lighter than the previous generation
Shimano put the emphasis on power, weight as well as the software component. The quality of pedaling and thermal management are also among the points to which the company has paid particular attention. In terms of weight in particular, the new system weighs 300g less than its predecessor. Indeed, it displays 2.6 kg on the scale. This decrease of about 10% is made possible by the use of magnesium.
A material that also helps keep the engine cooler. Shimano promises ease of installation of the EP8 to existing mountain bike models thanks to the same anchor points as the previous model. The ground clearance has also been optimized to ensure that the pedal does not risk hitting the ground.

Electric bike: forget the Steps e8000, the Shimano EP8 motor kit is coming!
More powerful than the Steps e8000, the new engine has a torque of 85 Nm, or 15 Nm more. An improvement that will undoubtedly be welcome, especially as a reduction in friction is added. Thanks to the use of more efficient toothed wheels, Shimano announces a much lower noise level as well as 36% less friction. This makes sense, because not only will the rider be able to pedal easily at high speed, but his electric-assisted bicycle will also gain in autonomy.
A focus on functionality
It is interesting to note that the new Shimano motor comes with two batteries of 504 Wh and 630 Wh. Its nominal power is 250 W (500 W peak). The three ECO / TRAIL / BOOST assistance modes are always there. However, thanks to the E-Tube Project mobile application, settings are now available to customize the torque between 20 Nm and 85 Nm. It is also possible to set the sensitivity of the assistance.
On paper, the Shimano EP8 therefore looks very promising. It remains to be seen whether it will be able to meet the needs of mountain bikers who, let us remember, have a myriad of offers ahead of them.
