All new, all much better. With 21 % a lot more torque than the E8000, now supplying up to 85Nm, when compared to the previous system’s 70Nm, with a highest ability output of 500W The EP8 (DU-EP800) isn’t just extra impressive, it has turn into extra compact and lighter at the similar time.
• 85nM torque
• 500W maximum power output
• Magnesium travel unit scenario
• Weight: 2.6 kg
• 36% reduction in drag when compared to previous version
• New assist algorithm.
Thanks to a magnesium push unit case and its increased condition the new motor has shaved 300 grams off the scale, coming to a full fat of 2.6kg. A ten p.c lesser variety offer provides even additional floor clearance over its predecessor. The motor mounts are even now the similar as in advance of, so bicycle brands can in fact suit the new motor into current frames devoid of any modifications.
Another significant advancement more than the old motor is a 36 percent reduction in drag and enormously reduced driving sounds. Heat administration has been optimized by introducing heat dissipating products, an greater surface area in the case and even a refined warmth management algorithm.
Speaking of algorithms, Shimano has wholly reworked their support algorithm for all of their assistance modes, organically matching the rider’s attempts and delivering the correct energy at the appropriate time. Alternatively of a one help ratio for just about every driving manner the new algorithm constantly calculates the great guide ratio relying on the scenario.
There is a new show, the SC-EM800, which seems to be incredibly equivalent to the recognized SC-E8000 but features a additional able chipset, expanded compatibility with third get together computers many thanks to ANT, and the capacity to pick two distinct personalized ride profiles. Also, with this display compatible new wires can transmit data faster thanks to increased bandwidth and make the system upcoming-proof for new capabilities.
A new handlebar-mounted guide switch (SW-EM800) with bigger buttons and bigger tactile responses is now accessible, as is a new chain manual (CD-EM800).
A 160mm crank arm alternative has been included to the 165, 170 and 175mm array, preserving the Q-issue at a slim 177mm.
Also up to date is the E-Tube Job application that can communicate with Shimano’s digital tools (Di2 shift elements also). In phrases of customization, the choices are expanded massively, making it possible for the riders to modify just about every ride mode with 10 unique assist curves to management how swiftly the electrical power ramps up to match their input. Moreover, the maximum torque restrict can be established in between 25 to 85 Nm of torque.
Most Shimano displays can connect wirelessly by means of Bluetooth with the app.
Thanks to a sequence of regrettable activities, I could not journey the new motor anyplace in the vicinity of as a great deal as could have been probable, but then once again, the handful of extended rides that I did get in, I depleted the battery every time and gathered some right tests impressions.
Merida’s 2021 eONE-SIXTY 8000 with carbon entrance triangle, blended 29/27.5” wheel setup and wise facts – like Thermo Gate cooling vents at the steer tube area to aid warm air from the battery to dissipate – acted as our test bike. With Merida and Shimano acquiring worked intently alongside one another when developing the frames that have been introduced in 2020, their whole vary has now been upgraded with the greater 630Wh inside battery (500Wh for XS sizing), improved Strength Guard battery protect with softer exterior product to cut down noise and enable sealing the battery compartment, further built-in cable routing, entrance gentle and of course the model-new Shimano Techniques EP8 motor. Our product was outfitted with Shimano’s SC-E7000 show, the two larger carbon models 9000 and 10K function the new SC-EM800 exhibit variation.
Time to play: good riddance to mistake W013 – the new EP8 can last but not least be started out up immediately with no any stress, even when pedaling.
It is rather evident just how a lot far more potent the new EP8 is. Not only extra impressive, but far more well-rounded, with torque efficiently progressing, no subject what mode you are running the bicycle in. Absent is the jerking motion that from time to time in particular accompanied the Boost placing. Even when setting up out in steep sections, the motor reacts very delicate to pedal input and it is alternatively simple to transfer the electric power to the floor and keep the wheels from spinning.
All of this at the feeling of how silent the new EP8 is, pretty much using it to a new stage in the group of whole-size motors. Even in Boost method, underneath complete load, the noise does not amass to a great deal a lot more than a lower hum, hard to even figure out in excess of the ambient noise of a experience.
Also, the base set up of the Trail mode has grow to be a great deal additional enjoyable to use. At the very least in principle, when checking the range concerning Path and Eco mode, it practically doubles in distance many thanks to their new algorithm. Obviously, the support from the motor is significantly a lot less in Eco as opposed to Boost, or now even Path, but I believe that there are nevertheless likely to be a good deal of people that will want to trip predominately in this manner to get some training in. Despite the fact that I have not at any time put in substantially time in Eco with the E8000, other than when I was in problems with my remaining array, the new guidance algorithm is also significantly affecting the least expensive guidance method in a optimistic way.
Despite the fact that it was not undesirable just before, pushing further than the 25km/h threshold also feels additional all-natural now with the reduction in drag, aside from the point that acquiring to keep a major e-bike at velocity will always be a little bit more complicated. As significantly as all round variety goes, the new EP8 system would seem to be benefiting from its increased effectiveness and should be appropriate there with its biggest opponents, though I’ll have to run my very little take a look at lap for some comparable figures.
Better than prior to, but nevertheless visible, is the transition each individual time you get started spinning the cranks from standstill and when halting to pedal. For absence of a far better description, it is form of a refined double-clicking resistance that can somewhat be felt as a result of the pedals and, if you pay back focus, even be heard. When it does not actually have an impact on the ride quality, I’m going to need to spend some extra time with the procedure to see if there are sure cases exactly where that sensation gets to be bothersome.
Most importantly, after you are pedaling, transitions from the motor assist is perfectly seamless and feels particularly pure. Kudos to the new algorithm.
At last, Shimano’s Stroll Method is now usable. Effortless to shift into and activated with the thumb remote, it pushes the bike along powerfully, no issue what equipment you are managing. At the force of another button, you are again to your typical riding manner.
Unfortunately, when attempting to join to our test bike with the E-Tube application there was an error, due to the fact the new motor was not component of the formal procedure however, so I can’t say to what degree the modes can get affected.
Even with as little time as I invested on Shimano’s new EP8, it’s safe to say that it is an advancement in excess of the E8000 in each and every single way. I will spend a great deal extra time with the new process for a in depth overview and run it head to head to some of its most important opponents to determine out in what regions it does perform better and wherever it nonetheless has some catching up to do. Remain tuned.
