The new Bosch Performance Line PX motor
With the new Performance Line PX, Bosch are expanding their motor line-up with a drive unit aimed squarely at trekking, SUV and touring e-bikes, closing a gap many riders might not even have noticed. While the Performance Line CX Gen5 is clearly built for sporty trail scenarios, the PX was designed to deliver everything frequent riders, comfort seekers and commuters are looking for.
Here are the key specs of the new Bosch Performance Line PX motor:
– Torque: up to 90 Nm
– Maximum power: 700 watts
– Support ratio: up to 400%
– Weight: approx. 2.9 kg
In terms of performance, the new PX slots in between the CX Gen4 and Gen5, and according to Bosch, it’s tuned for an especially quiet, smooth and controlled ride feel. The internals are different too: while the CX uses a 3-speed gearbox, the PX relies on a two-stage gear system. Needless to say, the PX is fully integrated into the Bosch Smart System and can be customised via the Flow app. It includes familiar features like Auto mode, walk assist and hill start assist. However, Bosch deliberately left out their Extended Boost feature– which allows the motor to push briefly after a short pedal input. It’s a bold but sensible move, since this is rarely needed in urban settings and on moderate tours.
New battery: Bosch PowerTube 540
With the new PowerTube 540, Bosch are introducing a fresh battery option for the Smart System, replacing the previous PowerTube 500. Despite offering 40 Wh more capacity, the weight remains unchanged. According to Bosch, the new 540 version tips the scales at around 3.0 kg and delivers a solid energy density of roughly 180 Wh/kg. Thanks to its identical form factor, the PowerTube 540 can also be retrofitted into existing e-MTBs – as long as they’re compatible with the Bosch Smart System.
Performance Line, Speed & Cargo Line – The urban workhorses
Bosch have also brought their urban powerhouses up to date, giving the Performance Line, Cargo Line and Performance Line Speed a solid upgrade. The updated Cargo Line now delivers a hefty 100 Nm of torque and up to 750 W of peak power for cargo bikes — a significant boost from the previous 85 Nm and 600 W.Despite the performance boost, it’s actually around 100 g lighter, tipping the scales at roughly 2.8 kg.
The Performance Line Speed has also been overhauled and remains built for use on S-pedelecs with pedal assist up to 45 km/h. It now matches the Cargo Line with 100 Nm of torque, 750 W peak power and up to 400% support – all at the same weight of around 2.8 kg.
The new Performance Line is a little more restrained, delivering 75 Nm, 600 W and 340% support. It too has been optimised, shedding around 400 g compared to the previous model and now weighing in at roughly 2.8 kg.
An interesting detail: the new Bosch motors are built on shared platforms with identical mounting points and very similar housing shapes. In theory, this means that manufacturers could use the same frame platform for different drive units– like the SX, PX and CX, or the Cargo Line and Performance Line Speed. The PX and Performance Line are especially close in design and are nearly identical under the hood. The same goes for the Cargo Line and Performance Line Speed.
Important: Bosch deliberately chose not to deliver the new motors at full power straight out of the box. Both the PX and Cargo Line come set to 85 Nm, 600 W and 340% assistance ratio as standard. The Performance Line Speed offers the full 100 Nm and 750 W, but “only” 340% support. The standard Performance Line, on the other hand, arrives with its full available power. You can adjust the motor output individually via the Flow app – provided the bike manufacturer unlocks the higher values. But more power also means more strain on the drivetrain and gears, as well as reduced range. So be aware of the trade-offs if you decide to turn things up.
Performance Line SX – now with eMTB+ mode and more power
The Performance Line SX is also getting a major software upgrade, and it’s especially exciting news for fans of lightweight eMTBs. From autumn 2025, the SX can be upgraded from the standard 55 Nm and 340% support – its default factory setting – to up to 60 Nm and a 400% support ratio, while maintaining the same 600-watt peak output.
But the real highlight isn’t just the extra power. With the update, the SX also gains access to the eMTB+ mode. Nice! This promises more traction, improved control and noticeably more confident handling in technical terrain.
Bosch eBike ABS Pro – now compatible with Shimano brakes!
Bosch are finally opening up the ABS Pro braking system to a much wider range of brake models. From summer 2025, Bosch eBike ABS Pro will also support Shimano brakes – including top-tier models like the new Shimano XTR and Deore XT, as well as more affordable variants like the BR-MT420 and BR-MT200.
And it’s not just Shimano joining the ABS party: new models from MAGURA, such as the Louise Elite and Gustav Elite, along with the TRP EVO Pro, are now supported too. Nice! This massively expands the range and addresses one of the biggest criticisms in recent years. As a result, we can expect to see far more e-MTBs equipped with Bosch ABS Pro in the near future.
eeShift 2025: automatic shifting, new partners, more drivetrains
Bosch are also opening up their eShift system to a much broader range of partners. Until now, eShift was only compatible with selected TRP and Enviolo drivetrains. Now, several Shimano groups are joining the line-up: the wired XTR Di2, Deore XT Di2 and Deore Di2 can now be used with eShift. For the first time, Shimano’s automatic shifting systems are supported too – including the NEXUS Di2 and CUES Di2. This makes eShift a much more attractive option for city and trekking bikes. Another new addition is Classified, whose Powershift 2-speed hub gearing is now fully integrated.
Flow app: your digital e-bike hub
With the MY26 update, the Bosch Flow app is getting a whole range of new features. One highlight is the Battery Lock function, which lets you lock the battery digitally. If the battery gets stolen and someone tries to install it on another e-bike, motor support is automatically disabled making the battery useless to the thief.
Also new is the Family Sharing feature, which allows up to five people to share one e-bike. Each user can save their own settings and track their individual ride stats.
If you’re curious how many kilometres you’ve ridden, how much climbing you’ve done or how many hours you’ve spent in the saddle, the new annual statistics feature gives you a clear breakdown right in the app. On top of that, 3D mapping with terrain profiles is now available for improved navigation – whether via display or directly in the app.
Important: the new features, including Family Sharing, 3D maps and annual statistics, are only available with a paid Flow+ subscription. The basic functions remain free of charge.
First ride impressions: the Bosch Performance Line PX on test
In our first hands-on test, we had the chance to try out several of Bosch’s new features: the all-new Performance Line PX motor, the eBike ABS Pro paired with Shimano BR-MT200 brakes, and the eShift system combined with the TRP A12 drivetrain.
The Bosch Performance Line PX delivers solid support, feeling noticeably smoother and more accessible overall than the upgraded CX Gen5. It’s also a touch quieter. Thanks to the two-stage gearbox, the drive system feels slightly more laid-back in character compared to the CX, which actually suits trekking and touring use really well.
The Bosch eBike ABS Pro, which we tested with the Shimano BR-MT420 brakes, performed reliably and discretely , offering a clear safety boost– especially on loose surfaces like gravel and scree. The eShift system with the TRP A12 drivetrain also runs smoothly and is easy to handle, which makes it a great option for beginners.
Conclusions about the Bosch MY26 Update
With the new features and updates for MY 2026, Bosch deliver meaningful improvements where they matter most: more power when you want it, more comfort when you need it, and added safety where it counts. Our highlights? The ABS Pro with its much wider brake compatibility, the SX power update with the new eMTB+ mode, and the Performance Line PX – which could pave the way for powerful yet more affordable eMTBs in the near future.
