Shimano Error E299 (EP801/EP600) - Anti Tamper Motor Lockout

Shimano recently introduced the new EP801 and EP600 drive units. With a host of efficiency, controller and usability upgrades and hopefully, some reliability upgrades these seem like a great choice if you are tempted to choose a bike fitted with a Shimano drive unit.

More information on the EP801 if you're not already familiar with it :


With the Gen4 motor, Bosch, were considerably more pro-active with derestriction recognition with the motor software. Error 504 appears if the system detects an irregularity with the speed sensor. Once you have error 504 , your speed is limited for 90 minutes until it resets. Alternatively, you can visit a Bosch service centre to have it reset. If you have this three times in a row, you have no choice but to visit a service centre for a reset. In the early days, there were several occurrences of the error when derestriction devices weren't in use, fortunately these problems were identified and rectified reasonably quickly.

Shimano have previously delivered anti-tuning firmware modifications to the EP8 with firmware 4.7.0, however, this was primarily intended to stop third party software being used to access the motor and battery data so owners could no longer accurately monitor the battery health in light of the various issues Shimano were having with the longevity of their in house batteries.

With the new motors, Shimano has taken a step forward and introduced Error 299.

You'd imagine that with Shimano's more recent history of unreliability, random errors, locked out motors and the total lack of factory supported repair of their motors added to a shortage of replacement motors often leading to long waits for replacements - that they might be showing a little humility. (For some reason, this is not exclusive, a minority have managed to obtain reasonable replacement times).

Error 299 is Judge, Jury and Executioner.

It's ok though, you can buy your way out of it ! At least initially.

If you do suffer from Error 299, either from the use of a derestriction device, an unfortunately anomaly, or Shimano's error code bingo system, you need to use Shimano's ASDP system (or have your dealer do it) :


Here, you can log the problem and PAY to have it resolved - once they issue you a quote to remove the error.

Resolution is then relatively simple (if it's a random error or not). Just remove your motor and have a dealer send the motor to an authorised E299 service centre to reset the error.

If error 299 is detected then your warranty is also voided. As we've seen already , to limit warranty returns in order to make the books look good, Shimano's policy is to void warranty at any given opportunity with zero come back for the owner. Yes, you install third party software, as it's now the only way to understand why your bike only seems to go half the distance it did 6 months ago. Warranty void ! The act of trying to prove that your battery is not conforming to Shimano's warranty - voids you warranty.

It's ok though, because lets say you do have a motor which randomly creates Error 299. After an (unknown at present) number of times the motor is permanently locked out !! You can't have it reset. The only option is to purchase a new one (assuming they will sell you one, which as most people who've tried to buy a Shimano motor will know - is no easy task).

Yes, it's landfill ! No re-cycling, resetting, repairing. Why's that ok ? Well, if you buy a new one, you'll get a new 2 year warranty !

The company with the worst ecological approach to motors and batteries manages to make things even worse and now uses software to make a perfectly good motor unusable. But yes, it's ok, you can buy yourself out of it again in the most wasteful way possible.

As if there weren't already enough reasons not to buy a Shimano powered bike, the company that gives with the latest version ... also takes away.

This is the reason I’d never buy shimano or Bosch ! Spesh know a high % will derestrict and don’t give a fxxk ! They will get my hard earned cash !
 
Omg! It would be ok if shitmano were on top of things..this is another example of a giant global business totally detached from reality🙈
 
While im not into 'tuning' or de-restricting it as a rule, if someone wants to then fair enough.
But from a manufacturers point of view it should void the warranty. You're forcing the motor to do something outside the parameters of the standard settings, which might be there for longevity, torque on internal components etc, and putting them under increased strain might cause premature failure.

Not true in many cases, here in Aus we are limited to 25kph and many use stun locker to apply the US limit of 32kph so not outside of manufacturer settings at all.
 
Is this error 299, just an anti speed limit removal measure,or anti using any kind of 3rd party software to talk to or adjust parameters of the motor,even if those parameters are the same as you can adjust with the official Shimano app?

It's not immediately clear at this point :

There is also E295 which is :

From their release, do they consider using third party software as not complying with national or regional regulations :

Shimano's web page on the subject :

 
Thanks, I read that text to mean altering the motor cut off speed,but I guess it could be more than that.

This doesn't seem too different to what Bosch do with their 504 error ,and it's not really a surprise they are doing it , a bit annoying though.
 
I have a feeling bikes using shimano motors will have to change.

Put me off buying a YT. Definitely wouldn’t buy one now.

The shit service would put me off buying shimano anything.
 
Why do the manufacturers are cares about that restrictions so much? Isn't this an end-user's responsibility to use the restricted bike in the public area?

All these motor "enhancements" make me keep my old eone-sixty with e8000 motor. Easy software derestriction and no clunking sound on descends. Looks much better than modern "upgrades" :)

I like mine as well, if only I could get a battery to last without degrading so quick
 
I had used Shimano 8000 for 2 years on the Norco Sight VLT. Tried the new EP8 but it's not that different. Specialized's Brose has a lot more torque and climbs on technical trail where Shimano struggles.

So already Shimano is an engine not up to the competition, if now it also puts all these restrictions, as far as I'm concerned it will no longer be considered.
 
There is a general problem with e-bikes in this regard.
You can't upgrade motors because of incompatability, you almost never is able to buy frame only options (with or without motors) and when warranties have been voided or run out it's not possible to easily obtain parts to repair or service the motor at home.
It's an incredible wasteful industry and it is clear that manufacturers does not care about the environment, they just want to sell as many of the latest motor as possible before they become obsolete 2 years later.
Bike manufacturers sell their brand with green colours and stories about replacing cars and mopeds with ebikes but at least I can buy parts for my car motor 10 years later and later down the line the steel can be used for something else. Carbon cannot.

yes.
And nothing will replace a car. For me an ebike is a toy for big boy, nothing more.
Iam using a car for my daily activities and i will, an ebike is for fun on forest on mountains only.
 
I rode an e8000 when I first discovered Shimano's attitude to Customer Service when it comes to motors. It was an unpleasant surprise to me because I had never had problems with Shimano in that respect, quite the reverse in fact, as I had only ever had really good service!

I was so surprised that I resolved to let my money vote for me and not buy another bike with a Shimano motor. But then I had 3500 miles of zero problems and when it came time to change the bike, I was captivated by the Merida eOne-Sixty. Unfortunately, it had a Shimano EP8! My resolve weakened and I bought it. In my defence, it was at the peak of the bike unavailability during the pandemic. I have since had over 2000 miles of trouble-free riding, during which I continue to read reports of Shimano's descent down the staircase to the basement level of customer service. Shimano would appear to be totally unaware of their declining reputation, or if aware have decided to do nothing about it. Shimano make more than just bike bits, so maybe it's not a large enough or profitable enough sector for them to give a monkey's?

Next time, even if I continue to have more trouble-free riding, I will not buy a bike with a Shimano motor (unless they have turned over a new leaf). Maybe when the bike brands stop buying their motors, Shimano will ask why and do something about it.

As individuals we need to decide whether this matters or not. If it does matter then discuss it with your biking buddies, mention it to any industry professional you meet (bike shops, trade shows, bike demos.....) Word will spread. If we do nothing, Shimano will not change.
 
I own a bike with Shimano ep8 motor, my first and last EP8, no more for sure.

I own a small business and I know I have to look after my customers to keep the business going. Happy customers are always coming back.

Shitmano - this is NOT the way....
 
I dont understand what exactly THEIR incentive to do this would be. Are there some legislatures who are demanding this of them?

These ebikes should all be derestricted as i see it. I certainly would not buy one where it is not possible. Bouncing into the limiter is just annoying and these bikes dont even go all that fast derestricted.

Quite frankly, these motors dont deliver alot of power even in turbo for anyone to make a big fuss about. Look at the tuned surrons people are riding with 25x the power compared to these class 1s. I dont get it.
