• Warning!!

    Riding a tuned or deristricted EMTB is not a trivial offence and can have serious legal consequences. Also, many manufacturers can detect the use of a tuning device or deristricting method and may decline a repair under warranty if it was modified from the intended original specification. Deristricting EMTB's can also add increased loads for motors and batteries. Riding above the local law limit may reclassify the bike as a low-powered bike, requiring insurance, registration and a number plate.

    Be aware of your local country laws. Many laws prohibit use of modified EMTB's. It is your responsibility to check local laws. Ignoring it, has potential implications to trail access, and risk of prosecution in the event of an accident.

Derestricting bosch smart system

It seems nice, and already asked how much will it cost, if by misfortune, the bike goes back to 25km/h limit. Does anyone knows if he request a further 180euros?
just don't update your firmware.
lets face it, if your out or warranty and gen 4, there's likely very little ever added in firmware updates that you will feel like your missing out on, might be a good idea not to update flow app either in case bosch try to force everyone to update firmware before letting them ride again... which would mean any bike with the wrong region is fixed back to peon speeds.

just read forum first every flow update :D

it's a 3minute process though so maybe he would do it for cheaper since you aren't really paying for the speed unlock
There's a risk they find out about it and they stop being a bosch dealer and could not do it anyway...
there's more than one polish shop doing it, but the other is 999 polish, which to me works out at 200£ where this guy was £161 = 200 euro

I have been driving 150km gen5 with the new update installed and badassbox. I only got 750w update. Haibike dont allowed the NM update yet.
I have exactly the same bike as you and bought just a couple of weeks ago. Are you still happy with the badassbox5? Any complications?
 
I won't update it anymore, there's no reason. One user wrote here that it worked using a VPN.It will definitely cost something, hard to say how much

I would just like to clarify that in my opinion there is no other solution on the market that is 100% error-free. I have been collecting information about all the chips on the market for several months and there are always problems after some time. So for me this is the best choice.

If you want to drive very fast 35+kh/m the risk of limp mode is even greater. 3x limp mode = you have to have it unlocked from the bosch dealer.
yes, for me 32 is ok! even if I go box/chip, I would set bellow 35km/h
 
yes, for me 32 is ok! even if I go box/chip, I would set bellow 35km/h
anything over 20mph is to obvious, and no one needs it on a trail anyway imo it's a "safe speed"
safer on roads, if you live anywhere with 20mph/32kmh urban street limits anyway like I do.
cars won't try to force an over taker if your matching their speed, where as if your doing 25% slower you might get some idiot taking rtisks and putting you and others in danger.
the whole 15mph crap makes no sense, your literally slower than you would be on an normal bike for the same effort.
 
Done.

I mostly ride enduro and 32 km/h is immediately noticeable, the ride is much smoother, it's more natural, a big difference and I'm finally satisfied :)

Of course, you hit the limit early on the road, the engine has power, but for my riding there is no need to go faster
I test drove the US firmware yesterday and it was such a pleasure not to experience the abrupt disappearance of support at 25 km/h
 
I just test drove mine around the local urban city centre area and it's so much better :D
Mine seems to cut out at 19.6mph / 31.54314 kmh
Motor feels exactly the same as before just faster.
.
but I easily hit 21mph when doing a gentle sprint to pick up speed again.
Huge time saver if you use your bike for anything else than mtb trails

I'm not saying I wouldn't like 35km/h, but we have what we have :D
 
Been looking at this thread for a while but wasn't really interested since I didn't want to swap out the rim magnet and still risk a bunch of errors.

However reading about the US firmware this seems like a perfect solution, however since everyone is being cryptic about it I'll just inquire as to which service you guys used, is it the phone number ending in .? How does the payment work? A bank transfer in your local currency at the current exchange rate?

don't do it , it's not for you. why ? because if you are at a stage of bank transfer concern ... let it go

Yes to most questions except the currency. He asked for 180 Euro directly in Euro, so in my case it was a SEPA transfer.
And yes, this is the most sketchy and risky part, as you are sending money beforehand without any official guarantee of anything.

Yeah, just remove the three digits from your post.


For me, sending €180 worked out at about £161. In my Lloyds banking app there are two fields for international transfers: one for your local currency and one for currency you select. If I choose to send in euros, I type in 180 in the euro box — The local currency will auto-fill. There’ was no sending fee with Lloyds, though the exchange rate likely isnt the best.


When I sent the money, the app said it wouldn’t process until 6:30 am. I then got a text around 10:30 am from him asking for my full name so he could confirm it was me (his bank shows him the sender’s name). After that he told me he could do it in 2 hours time.


I had my PC and bike ready a few minutes early, messaged him “Ready when you are,” and he started straight away. (you have to tell him the ID and password that teamviewer randomly generates, when he disconnects the password auto changes on it's own, but uninstall teamviewer anyway as you no longer need it)

The whole process took about three minutes. The longest part is downloading the ~700 MB Bosch diagnostic tool. He leaves it installed, and you can switch the language to English in the options. You can’t do much with it yourself, but it shows the same reports a dealer would see — with loads of hidden details you don't see in the flow app.
all the light ports on the motor are turned on with this firmware as well, so no issues with hard wired lights if you have them.

the actual flashing of the bike took maybe 30seconds, about 5 seconds for each component, with a few pauses as it went
Flow app will show your bike as a different brand, unless your bike is already that brand btw, but it makes no difference to anything, other than likely voiding your warranty if you had one.

you should be able to trust the guy. He has to provide his full name, address, and actual account details before you can make the payment. His shop also appears as the last service location in the Bosch diagnostics.
although maybe bosch catch on, and he carries on taking money but can no longer do it, possible risk but unlikely since hes an actual shop and angry people could turn up....


So far he's been 100% legit with it.

He’s also taking a big risk doing this — I won’t say exactly why, since I don’t want to give people ideas. You’ll probably realise once you’ve gone through it.


try to keep his details PRIVATE, any little thing, because the competition who make all the speedbox etc would likely report him in a heart beat directly to bosch

Bosch knows about this,because of the way gen4, gen5 smart systems works, lot of services or "dealers" doing this solution.

This solution started with the gen4 smart system years ago...it just wasn't "online" available for everyone.

Thank you so much for this.
I've asked him some questions, but seems he's not english fluent (neither do I... but it seemed less fluent or no time to spare!).

So besides having the bike to US settings (32km/h) he also:

1) install Bosch dealer software (wasn't aware of this!)
2) lights - do you have the battery limitation? Because when the port is active the battery will keep a % for light use (10% if I'm not wrong).
3) He can add Powermore - he answered this.

Only missing one question:
If by some sort of devil occurence, my bike returns to UE (25km/h) limit, will he set back to US for the same amount, or make a special price?

For 180, it seems a very nice deal!
I'm sold! And will go ahead after coming from holidays.

surely the shops would lose bosch status and no longer have logins for the bosch diagnostic software if caught.

bosch is so heavily anti tampering etc

2) lights - do you have the battery limitation? Because when the port is active the battery will keep a % for light use (10% if I'm not wrong).
3) He can add Powermore - he answered this.
Grok says reserves 2 hours, if port is set to 18watt it reserves 36WH which would be about 5% of a 750wh battery.
Probably not healthy to run a battery that low anyway, I dont like to go below 10-20% personally. and only charge to 100% every few months and leave it at 100% until it balances the cells and turns off.
most the time you wanna be between 40-60% when your not using it for storage etc as your probably aware.

He can probably turn both light ports off if u ask

Yes, the Bosch Smart System's intelligent Battery Management System (BMS) does protect against deep discharge and will maintain a reserve of power for light. When the battery charge gets critically low (at 0%), the system ceases to provide motor support but still activates a reserve function to power lights, indicated by a flashing red light on the display.

for power more I think your bike need the new style charging port.
maybe you can switch out the old port IDK, it looks like you can buy them, obviously the motor will be exactly the same, it will just be the cable the battery plugs into and running o the charging port, seems they come in different lengths.
you might wanna 100% check ther's no other cable to replace but I don't imagine there would be, it doesn;t put extra power through, just gives higher capacity..

What gave you the idea that I'm concerned? I'm just wondering about the technicalities. Since there's multiple people on this forum that seem to have been around for a while I'm not worried about getting scammed too much.

The whole process took about three minutes. The longest part is downloading the ~700 MB Bosch diagnostic tool. He leaves it installed, and you can switch the language to English in the options.

Do you happen to know if it's an installer? I'd let him do it on a vm just because I'm paranoid but I suppose it could also be useful to have myself.

He installs these, both downloaded from google drive, it's the obvious method to use though and doesn't mean they have been tampered with, obviously it doesn't rule that out either.
Nothing on my end suggests they are doing anything.
The bosch app runs 2 services in the background
Screenshot_2025-08-21-12-41-43-613_com.bosch.ebike.onebikeapp.jpg

but they just seem to be standard crap and you can goto services and disable them anyway or set them to manual start

The actual config file must be on a USB on his end, unless bosch use some kind of USB FOB stick for protection and he has to share it and make it look like it;s local on your machine.

If he was doing something weird he wouldn;t say "download teamviewer" he would give a link and tell you to download a trojan version of it instead that hides as a service in the background and doesn't let you know if someone is connected

instead you download it yourself from the official site, he never gives you any links, just says what you need

which is install team viewer free and don't bother making an account.

and install the vpn in its settings
don't touch anything else.

I also got it flashed by the Polish guy for 180€ bank transfer, transferred the money last night and he texted me back today. So less than 24h to transfer from Belgian bank to Polish.
He asked me to recommend him specifically. So I don't think he's worried about getting "caught", considering there's multiple people on that Polish website advertising this service out in the open I think either Bosch doesn't care, can't retract their license or they're using a cracked version.

I'm new here so I doubt people will trust my word for it but there are at least 2 other people on this same page with 300+ posts and year(s) of activity that have used the same guy that can vouch this is the guy.

Proof including visible phone number for those interested:

Does anyone know if he can add powermore functionality to gen 4 smart system bikes that did not ship with it? I have a friend with a scor 6080 and I was quite surprised that his new bike isn't compatible with the powermore range extender. I'd love to replace the charging port wiring harness for him and have the bike firmware flashed to accept the RE... if that is a possibility.

He can do that - it's a coiple of posts behind

my bike says power more ready, after the flash, but I still have the old socket.
seems you can buy the new style socket though, the normal battery end didn't change ? just the charging plug where the powermore connects as far as I'm aware.
 
You need t contact the person who can do it obviously and send them 180euro via bank transfer.
You need a computer or laptop.
you need a usb C cable to connect the bike to the computer (mini led remote has a USB C on the bottom, or the display thing that goes in the top tube screws out and has a USB C on it when you pull it out.
You only need to install
you don't need to register or anything just stay as guest.
and you need to enable vpn in teamviewer
He gains full control of your PC but you can see the mouse moving around, see what he's doing and if you want end the connection, he doesn't do anything he shouldnt by the looks of it.
He does install another thing as well as the bosch, but it's just for remotely sharing a usb stick
The guy does the rest, He doesn't remove the diagnostics tool, but if you change it to English without a bosch dealer ID there's not much you can do.

it does show tons of info about your bike that you otherwise can't see though. like the report a dealer would see.

Since you only have 1 post, it's unlikely anyone will tell you how to contact the guy, but on your own it's possible to find them.
Your bike in the flow app will now say it's another manufacture, unless your bike is from the one he uses..

If you do it you can never update the firmware via a phone or it will go back to EU peon speeds.
that's the only downside, maybe he would update for a lower fee or something if you already have it done anyway I didn't ask.

BTW your warranty likely goes bye bye even if it is a bosch dealer doing it. he's obviously not supposed to do it.
I wouldn't try to claim a warranty on the motor or he likely gets in trouble. cos the bike diagnostic shows the last shop to service the bike. (hes an actual shop)
my plan if I ever have any problems is to get a motor via the bearing man or someone else like that for 700quid or whatever and fit it myself.


My motor is 2 years old anyway so outside of warranty even if it's only done 1400miles.never had any issues the whole time.
I had to take the cranks off the other day to change the chainring, and the bearing seals on the crank/driveshaft whatever you wanna call it, they were barely dirty from the outside so I guess mines good for a long time and no water or dirt has got inside whilst riding. :)
Cheers, I know who/where and about the process from a different forum I frequent , so that's not an issue :)
The question I really wanted an answer to was about the firmware installation:
is he like using a VPN or does he have an offline version of the US firmware, or does he have an US Bosch dealer account which he uses to switch the region? basically wondering if you can replicate the process
Thanks for the elaborate answer!
 
why is so important to know all the magic ?! I mean pay , enjoy your ride .. why asking questions and questions ?!
I prefer not to be dependent on someone else to install software on my devices
Besides , I like learning the process behind stuff like this, and i'd rather be responsible for breaking my own stuff when tinkering with it than someone else doing it for me :p

you can not replicate the process without a bosch dealer id.
You can literally not change anything on the bike without one.
you can only see diagnostics and the configuration or service report.
even if you have the file he uses you can do nothing with it, you probably can't even clear an error code without logging in.
according to reddit dealers have a bosch security USB fob, it's probably what he shares over vpn with USB Network Gate software
My bike under service and reports literally lists his shop as the last place to service it, it's literally a shop with bosch dealer status not a jailbreak

Dealer services are locked down
