New Bosch Tuning License Key – Browser-Based Derestricting (No Chip / No App)

[Deleted member 9676]

Anyone can answer please?

There are two types of USB dongles for the old offline Bosch diagnostic tool. The IBD dongle is for bike services, dealers, and there is a factory dongle for bike manufacturers.

The cracked Bosch software emulates an IDB usb dongle ( dealer dongle), so you can't do tire size halving with it, you need a factory usb dongle for that.

Oh boy.....

No, you can NOT do halving with the cracked software, and cant fix 504 error either.

I purchased a smart license key of 179 euro to unlock my bike with bosch gen5. When i made a connection with my laptop and connected to the website to enter the license key it started with an update of my firmware. It stopped abruptly while it was busy with installing the firmware. After i disconnect the bike from my laptop i treed to turn on my bike. It just stays on for a few seconds and then the bike turns off. Now i have 3,5k bike that is useless. Guys from Mountain tuning dont respond on mails. I RECOMMEND EVERYBODY TO DONT BUY LICENSE KEY FOR TUNING. THE SERVICE OF EBIKE TUNING/MOUNTAIN TUNING IS WORTHLESS. THEY DONT GIVE A DAMN ABOUT WHAT THEY SELL AS LONG AS THEY GET THEIR MONEY!

Today I noticed the EBT can allow up to 45kph has anybody tried this yet? And can it be switched on and off on the bike or do you need laptop every time?
I was just about to purchase the smartchip now I see this I'm reconsidering however i have serious concerns about messing with the bikes firmware,what if something goes wrong?

So sorry to hear that bro, I have seen a few people online have bad experiences too, they don't look after their customers or even reply to emails. I hope u can get it sorted out,safe to say I will steer clear of this one..

Sorry to hear that, I hope you get it sorted out. I think it's best to just use Volspeed.

I wonder about this one as well, new member one post on the same day as registering the 2nd just 2 days later then nothing more, neither included their location, maybe a pattern?????

get a new motor will fix the issue

[B]MountainTuning[/B] can you confirm if the firmware would need to be updated before derestricting?
Do you have a list of what the latest supported firmware is?

I can picture bosch releasing a firmware update that could detect this method and then brick the motor. I would like to be able to confirm that the bike is on a compatible firmware.​

Hi, I’m Jens, part of the MountainTuning team. We’ve been working on tuning solutions for e-bikes and e-scooters for a while, and recently launched something that might be of interest to Bosch riders.

It’s called the EBT Unlock Key – a browser-based license key that unlocks the 25 km/h speed limit on Bosch Gen1 to Gen4 (BES2) motors.

The key idea:
No chip, no app, no firmware mod – just a one-time license activated via USB through your Bosch display (Intuvia, Purion, Nyon, Kiox).
It works directly in your browser (desktop/laptop) and uses the existing Micro‑USB port on the display.

Key Features:
- Compatible with Classic+, Active Line, Performance Line (BES2)
- Supports Intuvia, Purion, Nyon (1st gen), and Kiox
- No disassembly, no additional hardware
- Fully browser-based – no install needed
- Reversible and diagnostic-friendly
- Bosch Gen1 Classic + Intuvia: correct speed display
- Bosch BES2 systems: speed shown at half real value post-unlock (due to system logic)

More info:

Since this approach is still quite new (and quite different from the usual chip/module solutions), we’ve been getting a lot of questions – which is partly why I thought it might be helpful to share it here. Maybe this post can be useful to others, and maybe the forum benefits from having a space to discuss it.

We’re also working on expanding compatibility and features over time , though I can't go into detail just yet.

If there’s anything I should reword to better match the forum’s guidelines, I’m more than happy to adjust the post. And if you have any questions – technical or practical – feel free to ask.

Thanks for the space & your feedback,
Jens from MountainTuning
