New 2026 Bosch eBike System Updates - 100Nm torque upgrade!

The rumours were true. Of course, we knew - we just couldn't tell you! 

The Bosch Performance Line CX electric bike motor is getting an upgrade to 100Nm of torque, offering an increased 400% assistance - the same as you plus another 4 sets of legs pushing on the pedals with a peak output of 750W - and that's not all in the 2026 Bosch eBike system update...

A summary of the points covered about the new Bosch 2026 release in this article:

- Is this the first time Bosch has given their electric bike owners a free power upgrade?
- Why have Bosch chosen model year 2026, to give eBike owners 100Nm of power?
- Which Bosch motors are eligible for the free 2026 100Nm power upgrade?
- How can I get the new 100Nm Bosch electric bike power upgrade?
- When can I get the new 2026 100Nm Bosch electric bike power upgrade?
- Can I update my existing bike with the new model year 2026 100Nm power upgrade?
- Is the 100Nm Bosch ebike power upgrade the only update for model year 2026?

Is this the first time Bosch has given their electric bike owners a free power upgrade?

Nope! They've done this before, back in 2021.

The Generation 4 Performance CX motor launched in 2019 with 75Nm but Bosch never give up on a product at launch. They have access to a mind-boggling amount of user data uploaded to their systems each time a bike is plugged in with a dealer/repair centre and its rumoured that even 100Nm is well below the operating limits of the CX drive unit. Through continual monitoring and development of their systems, they can see where more can be gained in terms of power, efficiency and longevity.

In 2021, Bosch offered a free upgrade to CX drive unit owners by way of a software update. The only thing their owners had to do was pop into their local Bosch approved dealer and the update could be applied in just a couple of minutes and voila - 85Nm! 

Why have Bosch chosen model year 2026, to give eBike owners 100Nm of power?

We're not privy to all the commercial decisions that Bosch make, but they do generally keep well ahead of current market trends, especially with their user interface systems (displays and apps) which are easily the best in the industry and so it stands to reason that they would do the same with power outputs. 

Bosch don't like to just rush into things, though. As arguably the "worlds favourite motor" and with an outstanding reputation of performance and reliability to maintain, this would probably have been in the pipeline for the last couple of years. 

With the new DJI Avinox system pumping out 105Nm, the Rocky Mountain Dyname offering 108Nm and (despite their arguably far worse reliability data) Specialized's Brose systems offering 90Nm, Bosch were for probably the first time in the last 10 years a little behind and so had to respond at some point.

Although we don't think it should be the only consideration when buying a new electric bike - peak power figures do sell bikes and this new update for model year 2026 will have a big impact on sales rates of bikes with the latest Bosch Performance CX motor. 

Which Bosch motors are eligible for the free 2026 100Nm power upgrade?

At the moment, its just going to be the new "Generation 5" Performance CX motor (not its official, but seemingly commonly accepted name!) equipped bikes. In the trade, this is known as the "BDU384Y" motor. 

If you want to take advantage of the new 100Nm torque offering, you'll probably need to upgrade your current bike unless you bought it in the last 6 months!

If it helps - all of the 2025 model year Cube Stereo Hybrid ONE44, Stereo Hybrid ONE77 and Orbea Wild full suspension electric bike models use this newer Gen 5 motor and will be compatible with the 100Nm upgrade as well as all Cube Reaction hard tail electric bikes from the Pro model upwards. 

The "Gen 5" Performance CX motor was launched in late 2024 as a replacement for the Gen 4 although the Gen 4 is still a very good and well regarded motor after 6 years in production and is still being used by many manufacturers in current generation bikes. 

How can I get the new 100Nm Bosch electric bike power upgrade?

One of the massive advantages of the latest Smart System equipped bikes is the Bosch eBike Flow app. Not only does this have a huge number of features for the rider (Sat Nav, fitness metrics, etc), it also includes its own built in "mini" diagnostic suite and software update system. 

We're almost certain that this update will be available to owners "over the air", and will be offered with no more complication that any other routine software update. 

At worst, we'll be offering the upgrade to our customers at no charge when booking in to our workshop for any other work. 

When can I get the new 2026 100Nm Bosch electric bike power upgrade?

The upgrade will be already be applied to new bikes produced by manufacturers after 1st May 2025 but will be available via your dealer or the Bosch eBike Flow app in July for bikes produced before this date. 

Can I update my existing Gen 5/BDU384Y Bosch CX bike with the new model year 2026 100Nm power upgrade?

Yes! Those who already own a bike with the latest BDU384Y ("Gen 5") motor will be able to update their bikes around the end of July 2025 either by visiting their dealer or using the Bosch eBike Flow app when the function is switched on for end users. 

Is the 100Nm Bosch ebike power upgrade the only update for model year 2026? 

Nope! There are other new toys coming too...

The eagle eyed will have seen a neatly designed but fairly odd/out of place looking blanking plate being fitted in the top tube of bikes which use the Bosch Mini Remote and System Controller display system for the last year. We saw the very first of them being used by Cube on their Stereo Hybrid range of electric full suspension mountain bikes. 

Given that other models had a slot made just for the System Controller, it was obvious something else was coming and Cube were either looking to offer the option to their owners of future upgrades (very kind!), or, the reason for the bigger hole in the frame was late/didnt arrive in time. 

So what else is new for the 2026 Bosch eBike system in terms of components?

New Bosch Kiox 400C

The Kiox 400C is a trail-ready display that’s seamlessly integrated into the top tube, keeping it well protected from bumps and impacts.

Its dynamic screen automatically presents the most relevant data at the right moment, so there’s no need to switch views manually. Climbing? You’ll see your power output, cadence, and elevation gained. Descending? Your speed is shown clearly. A USB-C port allows you to charge devices on the go, and the screen delivers impressive brightness of up to 1,000 cd/m², automatically adjusting to the surrounding light conditions.

New Bosch eMTB+ Riding Mode

The new eMTB+ riding mode delivers dynamic support at the highest level, blending the smooth control of eMTB mode with the full power of Race mode—offering up to 400% maximum support. Extended boost remains easy to modulate like in eMTB mode, while unleashing the full force of Race mode when needed.

Power is delivered naturally and responsively, based on your pedal input. eMTB+ gives you the best of both worlds—combining agility, performance, and control for a truly natural riding experience.

New Bosch eSHIFT M+

M+ enhances eShift with an extra layer of automation when you’re riding manually. While you still shift gears yourself when pedalling, the system takes over during coasting—automatically selecting the optimal gear for when you resume pedalling.

This gives you full manual control when you want it, and smart support when you don’t. M+ reduces effort and ensures you're always in the right gear. It will be available via an over-the-air update through the eBike Flow app from autumn 2025 for TRP E.A.S.I. A12 systems.

Are you ready for a new 100Nm Bosch drive electric bike? 

Although our stock bikes will ship with 85Nm until post-May production starts to arrive, the update will be available to you via the Bosch eBike Flow app when enabled or when popping in to our workshops. 

We expect demand for the latest BDU384Y/"Gen 5" to skyrocket with this news and stocks of bikes with the latest CX motor will likely see shortages, at least in the short term as the end of model year 2025 approaches. We were already seeing stock shortages on some key models before this news and this wont improve so if you're keen to take advantage of the 2026 model year 100Nm model year before next years bikes arrive, now is the time! 

If you need any help with which bikes will be compatible with the 2026 update, please get in touch.
