Bosch already made its first big announcement of the year a few weeks ago. After the jump to 100 Newton metres and 750 watts for the latest generation of the Performance Line CX and the presentation of the Bosch Performance Line CX-R, you may be wondering what new products Bosch has in store for the 2026 season. Well, how about a completely new motor? Another intube battery? Or the long-awaited use of a single ebike by multiple people in the Bosch eBike Flow app? The manufacturer presents all this and more at Eurobike 2025 in Frankfurt am Main.
1. New Bosch Performance Line PX (BDU347Y) and other motors
2. Next intube battery with Bosch PowerTube 540
3. Bosch eShift for the 2026 season: new partners, more gear systems
4. Premiere from Shimano expands the selection for Bosch ABS

6. Schedule for the introduction of Bosch novelties for the 2026 season
1. New Bosch Performance Line PX (BDU347Y) and other motors
One of the most exciting new features that can appear in new products is undoubtedly a new motor. As the heart of the e-drive, it has a huge impact on the ultimate riding experience. Bosch’s latest unit, the Bosch Performance Line PX, is likely to be of interest to all fans of trekking and touring ebikes. At least, that was the target group during development. Until now, bicycle manufacturers had to choose between the Bosch Performance Line CX and the Bosch Performance Line. Those who were keen to experiment also considered the Bosch Performance Line SX. With its lower volume and weight, it offered advantages in terms of integration, but with a torque of 55 Newton metres, it lagged significantly behind the 85 Newton metres of the CX and the 75 Newton metres of the Performance Line.
Top-level performance figures
The new Bosch Performance Line PX now fills this potential gap. However, it cannot – or is not intended to – fill it completely. Its performance is too close to that of the Bosch Performance Line CX. This refers to the values that the manufacturer’s flagship model will have after its update in July 2025. The PX motor weighs just 100 grams more than a CX motor. Starting from a nominal continuous power output of 250 watts, it can generate a maximum of 700 watts. This results in a torque of 90 Newton metres – with 400 per cent assistance. Apart from the weight, these would have been the absolute top figures in Bosch’s internal rankings a year ago.
You can decide for yourself whether a trekking ebike needs such enormous power. Bosch has at least ensured a certain degree of differentiation in terms of acoustics. With a lower noise level, the Performance Line PX is designed to better meet the desire for a relaxed, quiet travel experience. This is perfectly complemented by the Auto mode available here. In this mode, the ebike system automatically selects the appropriate riding mode and regulates the level of assistance. With a tailwind, this should result in Eco mode, in which you can ride without lifting a finger. If there is a steep incline, the system automatically switches to Turbo mode, allowing you to concentrate fully on riding.
As usual, Auto mode and all other assistance levels can be customised in the app for the Performance Line PX. There you can also set how much motor power you actually want to use. If you wish, it doesn’t always have to be the maximum. The battery will thank you with a correspondingly longer range. After all, more power costs more watt hours. This also applies to the new motor in every riding mode.
In addition to Auto mode, you will find two features that are well known from previous models: the mandatory walk assist and the “Hill Start Assist”. The same applies to the way the motor is mounted on the frame. Once again, two screw mounting points are sufficient. Bosch introduced this motor mount for the 2024 season with the Bosch Performance Line SX. Since then, it has been used in all Smart System motors.

- Peak power: up to 700 watts
- Assistance up to: 25 km/h
- Torque: maximum 90 Nm
- Max. assistance: 400 %
- Variants: hub and derailleur gears
- Weight: approx. 2.9 kg
Revision of Bosch Performance Line Speed (BDU388Y)
The Bosch Performance Line Speed was added to the Bosch Smart System for the 2023 season. Three years later, it is now receiving a significant update. This primarily affects components of its gearbox and electronics. By decoupling the drive trains and switching to optimised gears, it is now essentially on a par with the current Bosch Performance Line CX in terms of technology. This basically brings the following five changes:
- bettter thermal stability
- 30 percent lower pedalling resistance
- 100 grams lower weight
- reduced noise
- motor mounting in the frame analogous to the Performance Line SX
The structural alignment goes hand in hand with the performance boost that Bosch already presented for the Performance Line CX in May. As a result, the torque increases to 100 Newton metres, the peak power to 750 watts and the level of assistance to 400 percent. In addition, the current Bosch Performance Line Speed comes with a Limit mode. Officially, this dates back to February 2024. However, very few of you have probably heard of it. When this mode is activated, the motor assistance ends at 25 km/h instead of the usual 45 km/h. In terms of the riding experience, the speed pedelec is then completely identical to a conventional pedelec. However, this does not override the legal regulations regarding registration or the ban on riding on cycle paths in Germany.
Bosch Performance Line Speed (BDU388Y) at a glance
- Continuous rated power: 250 watts
- Peak power: up to 750 watts
- Assistance up to: 45 km/h
- Torque: maximum 100 Nm
- Max. assistance: 400 %
- Variants: hub and derailleur gears
- Weight: approx. 2.8 kg
Bosch Cargo Line (BDU384Y) set to become more powerful
What has just been said about the Bosch Performance Line Speed can largely be applied to the new Bosch Cargo Line. The only difference is that Bosch’s specialist for e-cargo bikes will continue to make riding easier for you up to a maximum speed of 25 kilometres per hour. Anything above that will have to be achieved with your own muscle power. Otherwise, the same optimisations apply to both hardware and software. Compared to its predecessor, the BDU374Y, the new BDU384Y is 100 grams lighter.
Bosch Cargo Line (BDU384Y) at a glance
- Continuous rated power: 250 watts
- Peak power: up to 750 watts
- Assistance up to: 25 km/h
- Torque: maximum 100 Nm
- Max. assistance: 400%
- Variants: hub and derailleur gears
- Weight: approx. 2.8 kg
Noticeably less weight with the Bosch Performance Line (BDU346Y)
The Bosch Performance Line was already mentioned briefly in the section on the Bosch Performance Line PX. Bosch has obviously developed it further. This is evident, among other things, from a glance at its housing, which has been brought into line with all other motors and features the motor mount typical of the Smart System. A lot must have happened under the housing too. After all, it now weighs only 2.8 kilograms, which is 400 grams less than before.
However, this is not noticeable on the data sheet. The torque of 75 Newton metres, the maximum power of 600 watts and the 340 percent assistance are the same as its predecessor.
Bosch Performance Line (BDU346Y) at a glance
- Continuous rated power: 250 watts
- Peak power: up to 600 watts
- Assistance up to: 25 km/h
- Torque: maximum 75 Nm
- Max. assistance: 340 %
- Variants: hub and derailleur gears
- Weight: approx. 2.8 kg
Bosch Performance Line SX (BDU314Y) gains momentum
Increased performance does not necessarily require new hardware. Bosch underlines this with a small boost for the Bosch Performance Line SX. The motor’s torque will soon increase by almost ten percent and the assistance by over 17 percent. The new peak values will then be 60 Newton metres and 400 percent. The lightest of all Bosch mid-drive motors already had an outstanding peak power output of 600 watts. And that’s where it stays.
Nevertheless, it is astonishing how much reserve power the drives have and how much a software update scheduled for autumn 2025 can achieve in this case. Bosch may have felt a little under pressure after TQ recently launched the HPR60 in the lighter mid-drive motor segment. Bosch has gone one better, combining the higher performance with the eMTB+ mode, which will also be available on e-bikes with the Bosch Performance Line SX.
Bosch Performance Line SX (BDU314Y) at a glance
- Continuous rated power: 250 watts
- Peak power: up to 600 watts
- Assistance up to: 25 km/h
- Torque: maximum 60 Nm
- Max. assistance: 400 %
- Variants: hub and derailleur gear
- Weight: approx. 2.0 kg
Important to know: According to Bosch, the motors mentioned here are delivered ex works with restricted power. If you want to use them to their full potential, you must adjust the motor settings upwards in the Bosch eBike Flow app.
2. Next intube battery with Bosch PowerTube 540
What strikes you about the following series of numbers: 500, 600, 625, 750, 800? They increase in fairly regular increments, don’t they? Well, Bosch has certainly spotted a gap and is expanding its range of PowerTube batteries for the Smart System with a seventh model. The new Bosch PowerTube 540 provides a capacity of exactly 540 watt hours. It weighs the same as the current Bosch PowerTube 500, but has the dimensions of a Bosch PowerTube 600. How is that possible? No, Bosch probably didn’t just put fewer cells in the PowerTube 540 and fill the rest with air for practical reasons. Our tip: The Bosch PowerTube 540 contains older and therefore larger cells than the PowerTube 600. In return, the battery ultimately costs less in relative terms. It sounds a little confusing, but it could work. What is certain is that, like the others, you can combine the new battery with the Bosch PowerMore 250 range extender via DualBattery.
Bosch PowerTube 540 for Smart System
- Capacity: 540 Wh
- Weight: 3.0 kg
- Dimensions: 424 mm x 71 mm x 67 mm
- Compatible with DualBattery: yes
3. Bosch eShift for the 2026 season: new partners, more gear systems
With a view to further connecting ebike components, Bosch is expanding its range of solutions that can integrate electronic gear shifting directly into ebike systems for the 2026 season. Last year, there were already a few new additions in this area, primarily with derailleurs from TRP and Shimano. Both partners are now adding further shifting systems. TRP is introducing the TRP E.A.S.I. A11 derailleur with eleven gears and the TRP E.A.S.I. A10 derailleur with ten gears. With 12-speed, 11-speed and 10-speed gear systems, TRP now covers pretty much everything that can be used on e-mountain bikes, trekking ebikes and e-gravel bikes.
What Bosch and Shimano have put together is even more extensive. The Shimano Cues Di2, the only compatible derailleur gear system to date, is now joined by three extremely prominent groupsets. For the first time, bicycle manufacturers can now combine the Bosch e-drive directly with a Shimano XTR Di2, Shimano Deore XT Di2 and Shimano Deore Di2. Here too, the range now includes 12-speed, 11-speed and 10-speed derailleurs.
Improved software also for existing gear systems
In addition to the new hardware, Bosch has also announced improvements to the software. According to the manufacturer, the shifting behaviour will respond more quickly and directly to changes in the terrain or surface. This applies, for example, to shifting on climbs or when switching from asphalt to a gravel track. If eShift does not always make the best decision in your opinion, you can switch to manual mode at any time. As is well known, the automatic gear shifting system can handle manual, semi-automatic and automatic gear changes. A corresponding letter on the display and the Ride Screen of the eBike Flow app shows you what is currently set.
- M = manual shifting
- M+ = semi-automatic shifting
- A = automatic shifting
Those whose ebikes are already equipped with Shimano Cues Di2 or Shimano Nexus Di2 will also benefit from the optimised automatic function. An over-the-air update of the eBike Flow app is announced for autumn 2025, which will transfer the further development. Alternatively, you can have this done at a specialist workshop when the time comes.
For ebikes featuring Shimano Nexus Di2 hub gears, this update also adds the option of setting the gear you prefer to start off in from a standstill. We are already familiar with this feature from competitors such as Enviolo. Now Shimano is following suit.
New eShift option Classified Powershift
To our surprise, Bosch has also announced a partnership with Classified Cycling. This drive specialist has attracted a lot of attention in recent years with its 2-speed Powershift hub gear. Powershift is a rear wheel hub gear with an integrated planetary gear. In addition to the standard gear ratio of 1:1, the transmission offers a second gear ratio of 0.686:1. This means that a single fixed chainring suddenly has a second gear ratio. A second chainring and derailleur are therefore no longer necessary. And the eleven sprockets on the cassette, for example, suddenly result in 22 gears.
Technically, we find this very exciting. However, in terms of the ebike market, this initial collaboration is currently only a footnote. Classified has so far only managed to gain a foothold in this segment with Powershift among selected manufacturers. We are only aware of four current ebikes that use this special gear system:
- MCipollini Fybra R
- Flyer Usptreet SL 3.83
- Storck Name:2
- KTM Macina Revelator SX Prime
Of these, only the Flyer model comes with a Bosch ebike drive. However, Bosch and Classified will not have come together without ulterior motives on both sides. We will probably see new models with this combination in the foreseeable future.
Incidentally, regardless of whether the gear system is from TRP, Shimano, Classified, Enviolo, 3X3 or Rohloff, Bosch eShift can be implemented on almost all Smart System motors. The only exception is the Bosch Performance Line Speed, for which there is currently no corresponding option.
4. Shimano premiere expands Bosch ABS selection
Similar to eShift, Bosch ABS is one of the features that can set an ebike apart from the crowd. The manufacturer has invested a lot of energy in its anti-lock braking system over the past two to three years. Thanks to its targeted differentiation for different types of ebikes, it has found its way into large parts of the market. Bosch clearly intends to continue along this path. To this end, the system’s sensor technology has been modified. Instead of the previous sensor disc on the rear wheel, a sensor built into the motor now analyses the riding situation. Compared to the disc, it detects the inclination of the ebike more accurately. Based on this data, the system can detect more reliably whether there is a risk of rollover and can effectively support braking on the front wheel. In addition, revised software enables more precise control of the brake pressure.
For Bosch eBike ABS and Bosch eBike ABS Pro – the two versions of the system – there were previously two cooperation partners, Magura and TRP, offering compatible brakes. Shimano is now the third to join them. A total of four of its brakes can be upgraded with ABS. The eBike ABS Pro, which is aimed at professionals and racing series such as the Enduro World Series for e-mountain bikes (EWS-E), is likely to be found primarily on e-mountain bikes. The compatible brakes are the Shimano XTR (BR-M9220) and the Shimano Deore XT (BR-M8220). The Shimano BR-MT420 and Shimano BR-MT200 are suitable for almost all other ebike types in combination with the conventional Bosch eBike ABS.
Magura and TRP are also following suit and expanding their range. New additions from Magura include the Magura Gustav Elite for e-mountain bikes and the Magura Louise Elite for urban ebikes. Both can be combined with the Bosch eBike ABS. TRP is launching the TRP EVO Pro, a brake for use with the Bosch eBike ABS Pro on e-mountain bikes.
5. Battery lock and ebike sharing new to the Bosch eBike Flow app
With the update to version 1.26 for the eBike Flow app, Bosch introduced the option of registering multiple ebikes in the app for one person in April. This was met with a positive response in many forums. At the same time, there were many questions about when the reverse would be implemented, i.e. when a single ebike could be registered for multiple people. The answer is: now. Without a specific designation, the manufacturer is paving the way for people who share an ebike but want to enjoy all the benefits of the app while doing so.
This should be fairly easy to do in future. The person who owns the ebike can use the app to authorise other people to ride it. A maximum of five people are allowed. These people need to have the Bosch eBike Flow app on their smartphone. Via the app they receive an invitation. Then they can save a personal profile with the respective ebike on their smartphone. The crucial detail here is that if you want to authorise other people to ride your ebike, you need a valid Flow+ subscription. So the feature costs money. But perhaps the cost could be shared among the group.
Battery Lock to curb battery theft
The second new feature for the 2026 season, on the other hand, will be completely free of charge. And even more people may want to use this than sharing an ebike. With ‘Battery Lock’, you will soon be able to activate digital theft protection specifically for your ebike battery in the app. As soon as the relevant box is ticked and you switch off the ebike system, a security feature for the battery is activated, preventing unauthorised use. Only authorised activation of the ebike will unlock the lock.
A battery protected in this way should become a red rag to thieves. Not only can it not be switched on, but it also deactivates the motor of the ebike in which it was inserted during the attempt. For this to work as a serious deterrent, the feature must first become known among potential thieves and secondly, it must work reliably. If both conditions are met, criminals would at least have to completely remove batteries from ebikes with the Bosch Smart System from their procurement list at some point.
More overview – with figures and 3D
In addition to these two major digital new features, there are two smaller developments to report. The first relates to how terrain is displayed on maps during navigation. In future, this will appear in 3D on the Ride Screen. This gives you a better impression of the topography in the respective map section and allows you to estimate more accurately what awaits you behind the next bend or the next hill.
For all fans of statistics, Bosch is integrating an annual overview into the app. You can see the following data summarised for all ebikes that you have registered in the eBike Flow app:
- number of trips
- distance travelled
- travel time
- cumulative altitude
Both the 3D map display and the annual report require a Flow+ subscription.
6. Schedule for the introduction of Bosch novelties for the 2026 season
All new features that are in any way connected to the eBike Flow app will be rolled out in several stages with corresponding app updates. The first update to version 1.28 of the app will be released in July 2025. The new hardware will be gradually integrated into new models by the ebike manufacturers.
