500 km recorridos con Ep8 montado en una Orbea Rise H30, y ya empiezo a notar crujidos, y ojo que no es el clásico traqueteo que es intrínseco del motor, sino que dá la sensación de que alguna parte interna se está deteriorando,,,
Many people have commented on the noise that this motor makes during descents. I suspect that the chain guide, mounting points, battery mounts, internal cabling, etc.. could be contributing to this noise. Seeing the internals I wonder if the noise could be due to the motor using metal gears, etc.. I know that some other motors use some plastic/nylon gears inside which might be quieter but do not last. I would love to hear from a shimano engineer or designer on this issue. I would also love to see a new motor produced that has the same body as an old motor allowing older frames to be updated with a newer motor.
what is the cause of error E01022 ? I had 2 times of this. The 22 does mean what? Do I have to replace the whole motor? And It was just 27 months of old when it had the first error. I have ridden it almost in eco mode checking rpm 70-90 while climbing. Is this motor that weak in durability?
Internal sensor problem, it’s terminal and will get worse so yes you need a new motor. Most likely water ingress. Shimano will generally consider a warranty replacement In the first year after the warranty ends especially for this error.
@@AnotherMrLizard And I wonder how water ingress is likely because I haven't washed my bike. Very poor quaility motor I can surely say it is. Battery is still really good like new and the motor is dying just 2 year of use. What a master piece.
Hey Shimano I hope you have made this a servible item so it can be repaired and has parts back up. My E8000 broke and it was a throw away item that's crazy to make such items consumables. I'm not buying another Shimano unless it's repairable as it's a environmental crime unless it's repairable.
@@AClownsWorld well I like fixing my stuff you might be happy to chuck £900 motors away after a few thousand miles . If it can't be fixed I don't want it.
Depends what's broken - I replaced the internal bearings on my e8000 (along with a thorough clean of internals) which resolved my problems. But yeah, zero availability of spare parts by Shimano...you have to source a donor motor if gears are damaged or anything that can't be replaced by generic parts....this is unacceptable.
Dear Shimano - why do you persist in using a single housing motor, if multiple outer wind motors populated the circumference power could be applied to one or all windings. And not the full circumference needed to be populated, leaving the highest point vacant will lower weight. Plus much much more benefits from multiple drive.
Stéphane G. There are various videos and publications already out on this topic. Motor should bolt up to existing mounts, but wiring and plugs are different and Shimano is not selling the motors stand alone anyways.
@@bdub127 wiring & plug can have adaptators. Shimano to state if it is replaceabe or not. If yes, in which condition. Up to now I did not see any clear answer from the manufacturer.
Don´t buy , it rattles a lot and it is not eco -friendly by any means.Shimano built something unreliable and that can not be fixed or repaired just replaced.Save yourself the hassle.Even if the warranty policy is good.
first time i bought ebike i should put my ears plugs when i go downs that normal? i feel to retuning the bike, and bought a other brand. That rattles suck and drive me crazy . Only good think that scare the bears around
Hey Shimano, how can you seriously bring such a rattling engine to the market? After I've heard that, I won't buy a bike with an EP 8. When do you fix this rappel?
Doesn't seem like a very reliable system. W101 error from the first mile on my brand new bike. Will be returning it and going with a different manufacturer.
@@dustedstar5158 No. They're Not.. Gear boxes are heavy, complicated and require specific frame designs to offer shifting that is no better than derailleurs. The only, slight advantage is that stuff is protected, which isn't an advantage for the great majority of riders
@@richardhaselwood9478 A further advantage is instant gear changes, the ability to change gear while stopped and indexing in the gearbox rather than at the shifter, eliminating cable adjustment issues (Depending on the gearbox design, it will also allow you to pick whatever gear you need and use that to ride home if a shifter/cable breaks). Modern MTBs with 29" wheels, have the slowest gear shifting there has ever been at a given ground speed, purely because the wheel diameter is bigger, so it takes longer than smaller diameter wheels to do a half turn to complete a gear shift. Worst thing is they're 'fixing' it by reducing chain wrap while at the same time going to 10 tooth top gears, leaving a max of 3-4 teeth carrying the chain load, with attendant increase in wear, in a top gear that riders spend way more time in because its usually 2 gears lower than what was routinely available as top gear in 3x10 drivetrains. Now is the best chance gearboxes have ever had to gain popularity on bikes for a completely different reason and the reason is ebikes. Since the ebike motor mounting standards are being manufactured in large numbers and this interface can be used just as easily to mount gearboxes, the tech is becoming familiar to cyclists and shops, so there's never been more bikes for sale that could potentially have gearboxes. It's still north of €5000 to just get a frame and a Pinion gearbox (The only design that looks to have genuinely proved itself a match for the Rohloff 14 speed hub in reliability for long distance touring and hard off road use), and I can get a lighter bike for half that, so gearboxes still have an uphill battle. The lack of front derailleur compatible frames from most manufacturers, even on their models aimed at XC/marathon/touring applications means most of what's being sold these days is useless to me unfortunately, which is part of why gearboxes have got more interesting.
@@peglor None of these points offer any meaningful advantages to the very great majority of riders. Shifting speed, I've gone from 3x7 26" to a 1 x 11 29"er and never noticed any difference (there probably is, but subtle enough to be lost in noise from other factors). Cable snap.... I've snapped maybe 3 shift cables in my life mid ride. If you really need to get home, use your limit screws to put the deraileur in an easier gear. Indexing location.. Does it really make a difference? Bike Radar did a pretty good review of a gearbox bike about 2 years ago, and their summation was that it's not too bad, and pretty good in some ways, but they still have serious deficiencies in shifting quality, having to use grip shifters (*shudder*), needing to redesign suspensions because they don't allow for chain growth, and a couple of other factors (I can't remember now, too long ago). If people like them, fine, go nuts and get yourself one, but I don't get why their proponents keep going on about them as if they're announcing the second coming when, as I said, for most people, there are few if any actual advantages and serious disadvantages.
Corporates goals were met. Lighter, breaks and rattles.
Yeah it really seems like a piece of crap from my experience with the EP8
The sound of Shimano EP8: ¡Clac,clac,clac,clac,clac,clac, clac!

What is it with the noise on decents. You produce a product that is worse for noise and this is supposed to be better?
500 miles in...and my EP8 is broken. Should have stuck with my bosch

So, once the motor broke, it cant be repaired and become a garbage? Wow...
@@gpxjimmy exactly, Shimano should be ashamed. The repairability law may change that.
lol, just build your own motor. should we also shut down capitalism as its an encviromental crime?

will u be releasing a firmware update later on to give it more power more torque ????
What you want is called an enduro motorcycle, otherwise learn to pedal.

Wau..Perfekt
Is shimano grup set roadbike stop production? Anybody know???
Up
Is it compatible with E8000 if I want to replace it on my ebike ?
No and Shimano is not selling them stand alone

Shame on you Shimano , not eco -friendly, not fixable, rattles a lot . Won´t buy Shimano products again. They use to be wonderful ....
Don´t buy , it rattles a lot and it is not eco -friendly by any means.Shimano built something unreliable and that can not be fixed or repaired just replaced.Save yourself the hassle.Even if the warranty policy is good.
Anyone know the total reduction ratio--motor to crank?
Love mine! Don't knock it until you try it!
Are the gearing made out metal or plastic/nylon?
Metal
Some metal, some nylon

a Metric ton like all Ebikes
In the vid it says 2.6 kg

No thats for the whole motor. The new Rotwild with EP8 for example weighs in at 18kg

2,6kg :)
Sorry Guys.. to mutch rattle noises..
If only it didn't rattle it would be perfect. I won't buy a bike with it until they solve that issue.
SHITMANO

Das Teil ist eine Fehlkonstruktion klappert an allen Ecken und enden.
The system gives out error codes and Shimano refuses to help.
Dont buy this its unreliable AF
Couldn't agree more. Constant W101 errors for my brand new £3000 bike. Reliability stinks.
If I was Shimano, I’d delete this video and deny all knowledge of this motor.
