EP8-RS Derestricting Torque and Boost - eMax

[ep8-rs]

Please remember that the forum is normally used for discussion.

To declare everyone else's comments as "pointless debate" merely because they don't conform to your own views does not mean that they're not relevant.


Yes, someone else has also found a similar result to yourself, though one result doesn't confirm things, it could be subjective, different weather, different tyres the other bike riding slower for similar reasons.

Rather than playing some table tennis discussion based on "feeling" why not actually test the bike on the flat, with no wind, on the same day, where there are no trees or obstructions, in the same direction with a GPS device running to give actual speed. Make repeated runs to get averages using the different settings.

My apologies , that statement was not intended as a declaration towards others comments , but as to the debate of my experience by myself and the volley. But I can see how it could be read that way. Again , my apologies.

I do not have a GPS or I would take your suggestion to practice. Thus , only being able use the term experience.
I agree , one having similar results does not confirm nor deny things , I was simply grateful for being asked to re-read previous posts and was surprised to see it as I had missed it before. I was welcoming either result as I stated in the request post in hopes of a kind of vote system of personal experiences instead of continued volley. Looking at how this has all developed I am not sure that would really mean anything anymore. Just proof of my not attempting to mislead anyone at this juncture.

Thank you again for providing this forum.

For sure there is a difference if you will change the display speed adjustment value!
However, the only difference is the speed which is shown on the display, but as @Backflip already wrote, the real max. motor support speed of the bike does not change at all.
You even can change this display speed solely with your bike display – you don´t even need any smartphone or app!
Just enter the display menu and change the value and you will see that the motor support speed will not change at all:

Agreed , speed is not my intent , it is the abrupt cutoff of assist that was affected for me in comparison to no change and or -5 with my particular setup on my bike.

 

[ep8-rs]

I believe I did my best to reply to all.

Thank you all.
Best wishes

 

[Tony4wd]

In the end , my goal was to share my findings and I have done that.

In any case, thanks for starting the thread which showed me how to increase my Rise peak motor power to 500w - very happy with that.
The bike also seems to keep up better with our bosch powered bike, though I certainly defer to those knowledgeable about the software stating that only the display speed changes.

Regarding the display speed, the motor previously cut out at 24.3 km/h and now cuts out at close to 27 km/h (more than 5%) ?

Thank you Tony 4wd. Your reply is very much appreciated and I am glad someone found this helpful.

Your display speed curiosity would best be approached by Backflips information as I clearly never looked into that aspect. I only sought and found the increase in power and utilization of some the possibilities of the EP8-RS motor.

Super happy you had similar results.

So , this is just me standing behind the foundation my assertions toward authoritarians.

Petty as this may sound , the authoritarian stance the moderator with their sheriff's badge icon , for some reason got under my skin with their misrepresentation of my reply using the term pointlessness. As I apologized and stated my reasoning and or defense , I was hoping for a response from the moderator. I feel I have given it a reasonable amount of time for said response , and I even tried to directly contact the moderator only to find their account is not available for direct communications via their icon. Anyway , as I have not received a reply ( although this message would probably stoke a fire ) I feel this misrepresentation is all too standard in these days of elitist control over others. Yah , it's just a e-bike forum , and I doubt anyone really cares about this petty statement , but I'm still going to stand for what what I believe in. No one is above nor below any other one. Respect and decency for self and others flows in all directions , no exceptions.
One other showed they gained something from my wanting to help , so my goal was achieved and I'm happy with that.
So , if I get banned , so be it. I'm never posting here again anyway just as I feel it would be hypocritical , and a hypocrite I strive to never be. Ridiculously tiny in the big picture? Absolutely , but I have to be true to myself or it all is , well , pointless.

 

[Moderator]

I was hoping for a response from the moderator

Why ? We generally try not to post in the threads as it's a distraction to the primary discussion. If we do post, it's not to start a conversation as that would be a further distraction.

There was nothing to respond to ? Have you had a nice day ? Is the weather good ? Have you considered Pilates ?

You said you had no GPS device. You don't even have a smartphone ? There are lots of GPS apps which will display speed - you really want to have a conversation about this ? We're not here to tell you how to try and be more scientific rather than subjective.

for some reason got under my skin with their misrepresentation of my reply using the term pointlessness

Petty as this may sound , the authoritarian stance the moderator with their sheriff's badge icon

By misrepresentation, you mean directly quoting your own words ?

Maybe you can use this experience to help you understand how your words offended other members several times resulting in our response. You feel we misrepresented your words because of how we interpreted them. However this was the same for other members. In your initial reply you appeared to acknowledge this and understand how things can be miss communicated. Now you seem to have changed your mind and returned to your ideologue point of view.

As for the "authoritarian" stance of the moderator. We are obliged to enforce for forum rules and intercede when necessary. The tongue in cheek Sherriff badge - if that offends you what do you propose ? A gummy bear ?

if I get banned , so be it. I'm never posting here again anyway

Why would you be banned ? Your entitled to your views. Your welcome to post like anyone else.

Merry Xmas. The Mods.

I am sorry, but I disagree.
Sure does the display speed adjustment of +5,0% will have an affect, but only on the value of the speed which is shown on the bike display, but nowhere else...
The display speed adjustment which is possible in the range of +/-5% will definitely NOT change the real max. motor support speed of a Shimano STePS based bike at all!

Again: This "Display speed" - parameter only changes the indication of the speed on your bike display, hence the name "Display Speed" (which is an official wording from Shimano, see down below).

So, maybe you psychologically think you are going faster as soon as the bike display shows 27km/h instead of 25km/h at the same real speed, but it is still the same speed (this is a quite natural human behaviour).
This also has nothing to do if you are a "high cadence cranker" or not, cadence is not relevant in this case.

So, to give you another kind of proof again:
The functionality of the display speed adjustment was integrated from Shimano already in 2019 to the motor firmware of all Shimano STePS drive units (see the first picture in this forum post) and down below again.
See ""Display speed adjustable function for cycle computer" and also see the note: "Drive unit is controlled by the actual speed"):
View attachment 150972
BTW.: "cycle computer" is the wording convention from Shimano for their displays, "drive unit" is their wording convention for the motor.

Also you can use the same functionality in the official E-Tube-Project-software from Shimano (Bluetooth based Cyclist app and Windows based Professional program), see e.g. here in the E-Tube-Project-Cyclist app:
View attachment 150967
The shown parameter "Display Speed" will exactly represent the value which you also can change in the EMAX software.

So do you really think Shimano will integrate a functionality that will allow you to speed up your bike by 5% which in most countries is not legal?
Definitely not...

The EMAX team has integrated (copied) this functionality only to their software because in combination with a slightly decrease of the wheel circumference (which only is possible in the EMAX software with a valid licence key) you then can in fact increase motor support speed a bit more (due to the decreased wheel circumference) and still get correct speed values (due to the increase display speed adjustment) on the bike display.
So, in this case you decrease wheel circumference by -5% and increase display speed adjustment by +5%.

Believe it or not - it´s fact and I definitely know this for sure.
As written before I know these guys from EMAX quite well and they agreed to my writing...
Anyhow, they appreciate very much that you like their software a lot, so best regards from them.
As soon as they have some more time left in the (far) future, they will try to join this forum too.

So, if you don´t believe in my words, just write an email to the guys from EMAX and see what they will write about this topic. I think these guys know the Shimano system quite well...

Does this still work on 2022 Orbea rise?

Does this still work on 2022 Orbea rise?

The information "2022 Orbea rise" is not sufficient for answering your question thoroughly, because depending on the exact model type (e.g. H30 or M10), such an Orbea Rise bike can use the DU-EP600, DU-EP800 or DU-EP801 drive unit which all have different tuning possibilities. See in this document.
The DU-EP600 drive unit is marked with "EP6" on the right hand side motor cover.
To visually distinguish the DU-EP800 and DU-EP801 which are unfortunately both marked with "EP8" on the right hand side motor cover, you can have a look at this German forum post, or also this one.
Increasing max. peak power and max. torque on a reduced "RS" - drive unit with the eMax-Tuning software is definitely possible already in the licence key free version.
However, depending on the drive unit type and the currently installed motor firmware version, you easily can use the Bluetooht based eMaxMobileApp (for iOS or Android) or you have to use a cable-bound PCE - interface from Shimano and the Windows based miniMax - program.

EP6
Does it mean cant be derestricted?

Can it be replaced by EP8, or does it make sense to do so?

 

[Backflip]

So this is a DU-EP600 (EP6) based Orbea bike and you will find the possibilities on how to increase max. motor peak power and max. torque range with eMax-Tuning in chapter 12 of this document.
So, if you still have installed a motor firmware lower or equal 4.3.0 on this bike, then you easily can increase these values with the Bluetooth based eMaxMobileApp (for iOS and Android) already in the licence key free version.
If you already have installed the latest motor firmware 4.4.2 (which does not give you a single advantage at allcompared to 4.3.0, see here, go down to “Firmware Updates” and then use “Filter by Model No”, then “DU-EP600”), then you need to use a cable-bound SM-PCE02 interface and the Windows based miniMax - program for changing these values.
Take care: On a DU-EP600 based bike, it is not possible to downgrade to a previous motor firmware, so once you are on a newer motor firmware, there is no way back (like it was on older Shimano STePS drive units).
So always think twice and carefully check compatibility with the eMax-Tuning software before accidentally updating the motor firmware.

The bike is still new. Should have original software.

Thank you for the info Backflip.

I gather its possible to replace the EP6 with EP801? They both have the same power potentials seems like

 

[Backflip]

The bike is still new. Should have original software.

Software on a Shimano STePS drive unit is called "firmware" (because it runs on a so called embedded controller and has some specific and fixed tasks which differs from general software). Firmware on a Shimano STePS based drive unit is always "original", but depending on when you have bought the bike or on how long the bike was sitting idle in the dealers shop, the firmware version of this bike may be brand new (e.g. 4.4.2) or older (e.g. 4.3.0 if the bike was produced before June, 25th of 2024):

I gather its possible to replace the EP6 with EP801? They both have the same power potentials seems like

Yes, you can replace a DU-EP600 (-RS) with a (standard) DU-EP801 from Shimano (see e.g. here for a real cheap and brand new drive unit).
The "big brother" DU-EP801 is more powerful (max. 600W peak power compared to the max. 500W of the DU-EP600) due to the 300g less heavy magnesium housing which dissipate heats better than the aluminum housing of the DU-EP600 and so can withstand higher peak power.

What's the current position on this - assuming my bike and iOS software have all been updated.

I'd like to
- derestrict the power of the motor
- possibly increase speed from EU slightly (maybe to US 20mph spec)


For a 2025 Rise without a display (pre Orbea's own control, - version with the power button on the handlebar control), am I correct in thinking I need
- a Shimano usb interface (c £150)
- some extra cables? converters?

the Emax software (whats the actual cost of this??

Please ideally mention the drive unit type (DU-EP600, DU-EP800 or DU-EP801) your Orbea bike is equipped with, because depending on the drive unit type and the currently installed motor firware version, the possibilities of optimizion will vary, see in chapter 4 (DU-EP800) and chapter 12 (DU-EP600 and DU-EP801) of this document.
Also the connection possibilties (Bluetooth based or via cable bound SM-PCE02 interface) differ depending on the type of drive unit, motor firmware version and also additonal Shimano STePS components like the optional display.
The increase of the max. peak power and max. torque range can be done already in the licence key free version with the eMax-Tuning software. For increasing max. motor support speed you need a licence key. See also on the eMax-Tuning website and ideally contact the guys from eMax-Tuning for more information.

It's a Rise25 so EP801.

Depeding on the exact model type (e.g. M10 or H30), a "Rise25" also can be equipped with a DU-EP600 drive unit, so please always try to be as precise as possible with your bike details to avoid any misunderstanding and unnecessary delays.

Some personal thoughts to the “missing” display on some great Orbea bikes with EP801-RS and EP600-RS: This bike is missing the full potential of the DU-EP600 / DU-EP801 drive unit due to the missing display! You cannot use the new great FineTune mode without this display and just using the “crippled” SW-EN600-L left hand side remote control with just an LED! So we highly suggest to order the optional small SC-EN600 (or larger SC-EN610) display when ordering a Orbea bike with DU-EP801RS or DU-EP600-RS.
In my opinion, it is an absolute shame of Orbea that they mostly deliver their bikes only with the optional display and so most users don´t order this great display because the already quite expensive bike then is a few bucks cheaper!
Orbea is a great company and produces great bikes, however the decision not to deliver each EP6 or EP801 based bike with the SC-EN600 display shows that they don´t understand the new and great FineTune mode which makes such a display kind of necessary.
So, you can order and mount this SC-EN600 display by yourself, everything is already prepared (cables and adapters for the display are already inside your frame, see in the perfect bike related BluePaper - documents from Orbea which includes detailed cabling plans also).
The nice, small and light weight SC-EN600 display has many, many advantages, see and translate e.g. this, this, this and this German forum posts.
You can get such a SC-EN600 display currently for as low as 70€, see here.
Due to the fact that this display also has 3 ports and can act as a hub, you even don´t need any adapters if you want to connect the cable-bound SM-PCE02 interface which is needed for increasing max. torque and max. peak power or also max. motor support speed.

Also it is highly recommended to every Orbea bike user with DU-EP801 or DU-EP600 to create a so called “reset - cable”, see this German forum post.

There are many forum users in this forum who have posted about their (perfect) experiences with the eMax-Tuning software. See e.g. here, here, here, here, here, here, here, here, here, here and here some replies from very happy users just to pick up a few of them randomly.

Each to their own preferences. I really like that there is no display - I'm always going to be riding with a Garmin to track my rides (whether a watch or Edge head unit) and that's the best way to display info for me. At least the new display has a 10 segment battery life (the 5 segment one is useless - theres a huge difference between 40% battery left and 20% that catches out my friends on Bosch bikes regularly).

So going back to my original questions - for a EP801 without a display what do I need and how much does it cost?

Sure, each to their own preferences - absolutely.
I also absolutely agree with the 10 segments vs. 5 segments for the battery level indicator, this is a huge improvement on the SC-EN600 and I like it too.
Garmin tools are great, but are not fully compatible with the Shimano STePS system because they are "third party devices". There are currently e.g. still major issues with the new FineTune - mode which will not properly be shown on a Garmin device. There are some third party software tools for curing the situation like the "RS-Toolbox", however, this still is a workaround. So if you want a fully functional display without any traps, you need to stick on Shimano and use their inhouse STePS components.
This is why I always suggest to use the great SC-EN600 display which really is very small and fits perfectly between the corner of the handlebar and stem and does not bother at all.
If you don´t use the optional display, you need an additional EW-JC304 quadruple adapter and an additional EW-SD300 cable to connect the SM-PCE02 interface to your bike if you don´t want to dismantle (or at least lowering) the drive unit to get access to the Shimano STePS ports at the upper part of the drive unit which on an Orbea Rise unfortunatelly is covered by the bike frame. However, there are also some workarounds for this because there are already some adapters (as spare for the optional SC-EN600 display included in the bike frame). However, for this the exact type of Rise is needed, because these parts are on different locations inside the bike frame, depending on the exact type ("M" for carbon or "H" for aluminum bike frame).
For more informaiton, please concact the guys from eMax-Tuning via email, because they then will send you the bike specific whole prepared "package of information" with connection diagrams, adapter types etc. which will completely overblow a forum post.

 

[MeatBike]

Is this process reversable and detection free?

I'm not interested in increasing the power, but would quite like to increase the top speed to 20mph. However, I don't want to lose the warranty should I ever have cause to use it.

I'm also on a 2025 Rise with DU-EP801. Bought in January so I assume it's on the latest firmware version.

 

[Backflip]

Is this process reversable and detection free?

Yes, with the cable-bound SM-PCE02 interface and the eMax-Tuning software you easily can reset your bike to the absolutely traceless initial state in which nobody can detect any modification made before, neither your bikeshop, nor the bike manufacturer (Orbea), nor Shimano.
So there will be no problems in case you need to bring the bike to the bikeshop (e.g. for a service appointment or in case of a warranty issue).

So, just to confirm what I need -

- The EM600 display - you're saying I can connect this to my Rise 25 Carbon using the cables that come with the bike (theres currently a cable from the motor and one from the handlebar display that are joined in the stem with a connector). Those two cable swill then plug into the display.
The display will allow me to change between bike modes (what I'd like is to keep the RS+ profile with stock settings and another 'full power' profile for when I ride with people on full fat e bikes)
- The display has another socket to which I connected the SM-PCE02 computer interface

Then the emax software can talk to the bike/adjust the settings.

- The display has another socket to which I connected the SM-PCE02 computer interface

Then the emax software can talk to the bike/adjust the settings.

Exactly - there is nothing to add.

However, the optional display for your bike is called SC-EN600 - please ideally try to use the proper and complete component names from Shimano to avoid any misunderstandings. There also is the already existing SW-EN600-L control unit at the left hand side handle bar of your bike, which has a very similar component name.

Some hints:
Just replace the EW-JC302 adapter (which you already have found close to the stem) with your new display and you´re done.
Normally the 2 cables are having the correct length to connect to the new optional display. However, please check that these cable lengths are sufficient to mount the display to the handlebar in the corner on the right side of the stem (see on the picture down below) where the display is quite good protected. On a very few Orbea Rise bikes one of the cables seems to be a bit too short. So check cable length first. Maybe you need to order a longer EW-SD300 cable in this case.

The great BluePaper documents from Orbea also may help a lot because there are perfect cabling diagrams integrated.
Take care that you will get the correct clamp size for the SC-EN600 display - normally on an Orbea Rise bike the handlebar diameter at the middle, close to the stem is 35mm.

Best is to separate the clamp from the display and then carefully "open" the clamp (take care that the plastic of the clamp is not too cold to avoid any breakage when bending to open the clamp - you may gently use a hairdryer to warm up the clamp a little bit) and then you can snap the clamp on the handlebar.
We have done this many times already.
Also take care that any unused of the 3 ports of the display will always be covered by the related blind plug to avoid any water or dirt ingress to the connectors - the Shimano STePS system is extremely sensitive towards leakage currents which can be greated by such dirt and water and resulting corrosion of the contracts.
