For all those who have not used the etube app, you can change the motor behaviours, start up tourque and a heap of other perimeters which negate some of the issues noted here. I love my ep8 and the noise is almost impossible to hear.
Thankyou. You're the only reviewer in the e biking scene I trust - the others are mostly saying what they're paid to say.
This is exactly whats the point with all the other channels... They say for what they are paid for.
This is the 2nd video I watched from the channel and I'm inclined to agree with you. I don't like how others talk to the camera to gain trust. I understand some people prefer that. I much prefer some sort of evidence to review in order to verify claims, and I like how it's delivered here.
This is the best review i have seen so far of this nature,cheers.Some of the nature trails in the video remind me of some areas aound Songsvann.
Thanks for the very informative test!
Excellent video. This was a good test. For me as a person who wants to buy the first e-mtb it is really hard to decide with motor to go for. There seems to be no perfect motor, but the EP8 seems to be a good choice. I would be glad if shimano would have solved the rattling noise.
nice review.
I ride Trek Rail 9.8 with the Boch C4 performance 625 battery& the last update-the range and efficiency is amazing-riding 50 km climbing 1000 m and consuming only 50% of the battery.
after 6 month 1 service mostly for the update.
compare to the climbing descending stability and suprisng range some noiseis nothing and even start to like it.
so the developments of the engines and the EMTB are remarkable
servise and reliability are the most important
Thanks for the great technical review !
One note, you said the "noise seems to be caused by the chainring hitting the motor internals in some way." You mean to say the crank spindle.
Not really sure if Shimano's answer stands up to logic as if they are saying required free-play in the bushings is a necessary thing. It will get louder over the miles of use I suspect in Gen 1.0 of a new motor. Then in Gen 1.x they will have taken care of it...quietly :) . Hope St-Unlocker comes out with a version for the Ep8. I could not ride an e-bike as an efficient training tool customized to me and not the other way around; without it. For instance my DU-E8000 motor with the robot silly e-tube app only customizes to 33% increments in the 3 modes. St-Unlocker makes infinite level of % customizations. Example: 21% eco, 43% trail, 72% boost. If I need to change it on the trail, it works so infinitely easier than e-tube, you can do it in about a minute.
Great for non robots !
Excellent review as always. After the release of the EP8 and latest Bosch firmware update is the Panasonic motor still your favorite?
Awesome review.
Thank you for the review. And Shimano for the 2 profiles. I wish there was a way to add that to my current bike....
I was going uphill yesterday and was really-really missing a "4th level" at least. Turbo was too much, but Trail just didn't cut it.
I find the previous Bosch's eco-tour-emtb-turbo almost perfect.
Also, while I am tempted, I am not going to replace a not-even-1 year old Pivot Shuttle ($10K XTR model) up to have an extra setting on it.
I really wish Shimano rolled out an upgrade for the older models with either a profile, or just a 4th "curve" ...
But of course they want you to just get the new stuff....
@@EMTBVideos Yep. I have eco: high, trail: mid, boost: mid. And it would be really nice to flip the trail to high or the boost to min at times.
But with trail in MAX, then it is a battery killing option. It is steep and hot and wet here in Costa Rica and you can get as little as 25Km on a full 500Wh battery in trail mode, because that 25Km has a 1400-1500m vertical in it. If you consider that half of it is coming down, then well, it is pretty steep :)
@@EMTBVideos Also ... I would happily pay a $100 or $200 and just get an upgraded display for the e8000 to have more options. But to replace a $10K bike for this is not something I would do :O ... maybe in a year or two :)
coming from a massive E8000 fan boy here there is no way id get a EP8 anytime soon as bike noise really pisses me off. I'd rather have the motor noise of the e8000 over that horrid rattling in the EP8. I don't care what they say, a knocking sound from a motor is never good and will affect how reliable it is in the long run. Great review, still a massive fan of the E8000. I think the makers should be focused on making more reliable motors before making them lighter and smaller. Both Shimano and Bosch motors have stupid code issues. Shimano with their E010 codes and Bosch with their 500 codes! sort them first!
EP8 ain't available till January time for improvement you think??
@@mayhemnmadness9266 hope they cure that knocking for sure
Marky Mark me too I’m a car guy and fook any kind of noise or vibrating does my head right in so aint gonna be able to put up with that kind of extreme knocking
@@mayhemnmadness9266 hahaha so am I and I have to have a completely silent ride. If I get any strange noises I will also sort it lol
Marky Mark ordered the Orange surge with this motor on for January now I’m concerned
Best review by far
For me the Brose T and S are the quietest and most natural feeling motors on the market. I also believe that with the latest model year and software updates their belt snapping issues are a thing of the past.
Did you have the latest firmware on the Bosch? I just got mine updated to the 85nm version and it definitely feels different. The power delivery is smoother. Like other folks, I thought that something was wrong because the bike felt slower but when I checked the time on the loop around my block, it was about 10% faster every lap then I could do before.
Excellent review!
Any idea about range ? I see a lot of Shimano E8000 motors equipped with a +600wh battery, but still some reviewers mention only 35kms range on turbo settings. That is in my opinion not much of an improvement over my gen2 performance line cx with 500wh, I get about 40 kms out my 2019 KTM bike on turbo ( on a 40km course consisting of offroad, mostly flat, some climbs, but riding a lot on /mud sand and on the beach ). I really was expecting those 600wh batteries to show some range improvements. What is your guess on range ( between old cx, new cx, e800 and ep8 ? )
It would have been interesting to compare the EP8 to the Performance CX with the 85Nm power update.
the noise is a clear showstopper.
The EP8 has some issues with pre production and when recently tested it was the least powerful. See EMBN Motor Test. The new Bosch motor was the most powerful and is now 85NM. The Shimano motor failed ISO tests and had some casing cracking. They are trying to fix everything and go into full production
I would like to know how bad the retailing noise is for the components.
Similar rattling noise with E7000 I have. The chainring also has lateral play about 1mm, which shimano said it is within the specc.
How about EP8? Any lateral play when you push the chainring with both thumbs?
You can check my video, to see if you can hear the rattling noise. It's there, but not too bad, I get used to it.
Great review! 👍 is new shimano much louder than brose s mag or quite simmilar?
Brose s-mag is good if it runs. :-) My wife and my friend have one. There is not a month when one of the bikes is not in the service. A friend has already replaced the engine. Wife repaired 3 times. Each repair takes 2-4 weeks! The 2020 season is running out. Unfortunately, brose s-mag is s..t!
Well my brose is running already a year now and completely no problems. But I can imagine it's annoying... But the positive thing is that competitors are catching up in terms of quietness which is a priority for me. Glad about this!
@@j5k395tks Congratulations. Maybe you are driving in the park or small mountains. We explore the Carpathian Mountains in Poland. My shimano (merida e-one 900e) has been good for two years now and the brose has failed many times. Nevertheless, Specialized has very nice bikes, but very bad service. Regards, Bro.
TL dokładnie tak. Niewielkie wzniesienia. 😉 może dlatego jeszcze jest ok. Ale mam gwarancję wydłużona do 4 lat także się nie martwię zbytnio. Podobno teraz problem rozwiązali!
@@TL-fn8iv I've had one in my Levo Turbo for two years with zero issues
Awesome review 😁😁😁👍👍👍still no brose 🤣🤣specialized rules
Gray squirrel tree service Yeah.... just keep changing the motors in the Levo 😄
@@tamasvarga67 exactly they so good who wants to ride anything else🤣🤣🤣🤣🤣👍👍
Gray squirrel tree service yeah they are awesome... spend the season waiting for motor replacements 😂
Levo at the bottom of the e bike list for me. Dodgy motors and waaaay overpriced. Specialized take the piss.
@@ozPanzer no motor is best fixed now
Why do you always forget about the wolk mode review? On the E8000 with a mechanical rear derailleur, it was very bad, only the swap to Di2 saved it.
I am wondering if the Bosch motor you were using had the latests software update that just came out?
@@EMTBVideos Cool, I just sold my Cube Stereo with the Bosch motor because I want to buy the Luna X1 with the befang motor. All these big name bike makers are using the European model for designing ebikes and they could take a lesson from Luna Cycles! ruclips.net/video/AD8cdxW3U54/видео.html
Did Shimano make all three motors the same bolt pattern to be interchangeable ,I thought the E7000 and E8000 wherenow the same size other then the power. Also I’m getting two answers is the 7000 only 60 neorealism is it 70 nm.
Does the e8000 display your power input like Bosch kiox
I consider about rattle noise in EP8 and I have some idea. What if we put 24mm wave washer between crank arm and sprocket? That would make some friction between them just like your finger in 2:53 and it should make it more silent. That friction should not be very strong, so it should not affect motor "runover" when you stop pedaling. What do you think guys? I've got two ebikes, one with E8000 which is perfectly silent in my case, and second with Bosch Cx4 which annoys me (rattle noise), and I'm going to sell it.
Interested how you would compare the ep8 to the Rocky Mountain
Thanks for your response. One more question. How would you compare pedaling beyond the motor cut out at 20mph?
Has anyone actually tried the putting an EP8 in a bike that came with an E8000 stock? I’ve heard (from a credible source associated with Shimano) that there’s some question in it’s compatibility. The E-Tubes wires are a bit larger on EP8 equipped bikes for one. Also, the EP8 is under recall. So the future is uncertain...
This video is without a doubt the most insightful and comprehensive review of these motors and their behavior ever . No other reviews even come close .
a brilliant presentation. 👍
SALVE, XCHE NON DITE DEL CIOTTOLIO CHE FA IN DISCESA IL MOTORE A PEDALI FERMI,SEMBRA CHE CI SIANO I SASSI NEL MOTORE.
Any anti tuning software?
So.... the EP8 has been recalled? Seems like the noise they were happy with will now be addressed
@@EMTBVideos not good 🙃
@@EMTBVideos Any update on what changed on the EP8 after the recall? I do like the fact that the EP8 motor is so quiet during climbs.
i wonder if shimano offers retrofits or if this is possible at all
Shimano to answer clearly this question.
Sir ,please disassemble the shimano ep8 motorbike, want to know if the gears use metal or plastic 🤔🤔
@@EMTBVideos but in your opinion , the shimano ep8 motor, usses all iron on its gears or there are still gears that use nylon plastic
Can these motors be swapped?
Most of the ebike test done on downhill :)
Did you noticed the clamping sound once going down?
He compares it with sound clips of the Bosch and e8000 in the video. Not much difference between them by the sounds of it.
Screw the newer is better con. I'm happy with my E8000. EP8 isn't more powerful, it's b.s.
I wonder if it is still sealed non-servicable motor? From what I heard, when you get a rattling bearing on shimanos you can throw away the motor and buy a new one.
@@EMTBVideos Thanks for reply ! :)
Its ridiculous that they can't be serviced. I had a horrible noise coming out of my E8000 after 3500km. I had to open it up to see what the problem was. All the bearings were fine but one of the gears had gone dry of grease. I applied some freash grease and it sorted it for a while. It looks like I'll have to do this periodically.
Please review the new Bosch with 85nm and maybe compare with the EP8
that noise might not effect the performance but if everyone had their head screwed on it surely will affect the sales as who wants a rattly motor ,this is so wrong. They are trying to make these motors smaller and smaller and lighter but hey we don't care about small we want bigger and more reliable and quieter.
Quite. If your spending 4 or 5k (or more) on an emtb it’s not an unreasonable expectation.
i'm thinking that there is too much emphasis on weight where e bikes are concerned .
on a racing/ road bike , weight is everything but on an ebike it is not such an issue to have one or two kilos extra compared to other systems , if it gives better noise reduction , reliability and heat dissipation.
@@EMTBVideos good points . i'm a much older rider (75) so handling at higher speeds is not an issue for me anymore , meaning i ride with my brakes on when going downhill . 😂
when i was younger it was an issue but still with an ebike a little extra weigh is not such a big deal .
Can replace the E8000 on current bikes ?
Yes
@@EMTBVideos it is a pity if Shimano did not take into account E8000 retrofit capability.
Supposing I change for a new ebike in the future, not sure to invest in a Shimano motorisation.
How will that work if it’s 10% smaller?
@@Fishster same packaging they say.
stephane GARNIER - ahh OK on the video they mentioned 10% smaller. Perhaps it should be 10% lighter.
Wow noisy when going down hill
le poids est l'ennemi du bien :)
МОЛОДЕЦ
This is an unfair comparison, you need a gen 4 bosch with 85nm then compare....
What about Brose smag? think this is the best engine ....
brose s-mag is good if he running. :-) My wife and my friend have one. There is not a month when one of the bikes is not in the service. A friend has already replaced the engine. Wife repaired 3 times. Each repair takes 2-4 weeks! The 2020 season is running out. Unfortunately, brose s-mag is s..t!
Sorry, for me a rattling motor like the Bosch Gen4, Sachs RS or now Shimano EP8 is an absolute no go. What's the matter with the designers?
Nicpain81 Rattling is not really noticeable/disturbing in real use with the Bosch and I guess it’s the same with EP8. Rather have something that’s working than having an unreliable motor and waiting for replacements all the time.
@@tamasvarga67
I find it extremely annoying. Let's see if the Smag will be more durable after the software and hardware update. As long as it's running there is no alternative for me.
Nicpain81 Have you tried either or just saw the video? My friend has a Bosch gen 4 and didn’t notice anything - I rode it and me neither. I have E8000 problem free for almost three years while I have a friend on the fourth motor in his superior Levo - missed a whole season- and he’s not the only one, all Levos around me had their motor replaced. That’s total crap for me...
Bosch still the noise king going downhill
Ride Levo.
And what about derestricting?
Are there any protections against inztalling one ?
I do not accept 25kph limiter such bike is useless for me.
Heard about "badassbox"? You just modify the magnet to give half the signals. No modifying the software. Should work with all magnet speed sensor ebikes. Haven't tried myself but thinking about it for some offroad fun. Want to be 100% legal.
@@erafune4723 Badassbox or other chip means aditional cost and does not work with newer bikes or older with newer software installed becasuse of special algorithms in software that recognise unlocking devices.
let me guess - nothing )
UPDATE:
Shimano has halted production of this motor due to “issues”.
It might be back into production by December of this year........might be.
Go with Bosch......proven.......and you’re buying a system i.e.: motor, controller and battery.
Not so with Shimano and any other manufacturer that I’m aware of.
You’re welcome !!!!
Bosch can't be unlocked anymore, that's a showstopper for sure.
It’s rubbish
