Key to upholding their reputation for being the most advanced and reliable drive system manufacturer, year on year, Bosch continue to develop new products while providing reliability and performance upgrades for current generation products and for 2025, we're getting a host of new hardware and features as well as a handful of updates to currently available products.
What's new with the 2025 Bosch eBike system?
Its been 5 years since the Performance CX motor last had a significant overhaul and launched to the market with 75Nm in 2019. In June 2021, this was increased on new motors as standard and available as a software update for compatible motors already on the market to 85Nm.
Although we've already had a handful of new battery form factors/capacities since the launch of "Smart System" in 2022, Bosch have launched 2 new variants for 2025, along with a brand new display and a couple of Bosch eBike flow updates. Bosch eBike ABS is also being much more widely adopted by manufacturers for the 2025 model year, signifying much greater confidence in the technology and demand from consumers.
Is there a new Bosch eBike motor for 2025?
Bosch Performance Line CX (BDU384Y) motor
The new Bosch Performance CX motor retains the same 85Nm, but its outer shell and some of its internals have been redesigned and reconfigured into a smaller, lighter package with mounting points moved in order to allow bike manufacturers, particularly those using the new "Generation 5" Performance CX motor in full suspension bikes, much greater flexibility in the way they mount it and the position of the pivot point at the bottom of the suspension.
As well as a new outer case and mounting position, the motor weighs in at 3.5oz less than the predecessor, produces less riding noise and reduced resistance as well and a new "Hill Start "Assist".
Hill Start Assist offers a similar function auto-handbrakes on newer vehicles. When starting on a hill, the the motor will "hold" the bike and stop it from rolling backwards on inclines, giving the rider much greater confidence when pulling away uphill, especially on heavier bikes.
The new "Gen 5" Bosch Performance CX joins the Bosch motor range to compliment its offering for every type of bike.
Are there any new Bosch eBike displays for 2025?
Bosch Purion 400 Display
The new Purion 400 display joins the rest of the Bosch electric bike display offering, specifically designed for mountain bike trail riders. Nestled in the triangle area of the bar/stem assembly, its 1.6" full colour screen is conveniently protected from debris and crashes by stronger components on the bike.
The new Bosch Purion 400 is cross compatible with all Smart System equipped bikes from 2022-onwards. It can be fitted in just a few minutes and is ready to roll the moment its connected.
Bosch have designed the new Purion 400 display to be read in an instant. Its high contrast, full colour display gives provides battery status, speed and selected power mode settings at a glance, with more in depth information available when scrolling through further data fields.
The Bosch Purion 400 display for Smart System equipped electric bikes is just one of a range of displays Bosch make for their ebikes, all designed to suit a different type of rider or riding style.
Are there any new Bosch eBike batteries for 2025?
Bosch PowerTube 800 and PowerTube 600 batteries
As well as a new motor and display, Bosch have also launched two new batteries for 2025. The Bosch PowerTube 800 and PowerTube 600 batteries are "in frame" batteries, designed to be neatly integrated into the frame of electric bikes by their manufacturers for the best level of protection, performance and aesthetics.
When we first heard about the addition of a Bosch PowerTube 800 and PowerTube 600 battery we were at bit confused as to why it was necessary. The PowerTube 600 battery is 25Wh less than the PowerTube 625 which already exists. Likewise, the new PowerTube 800 battery is only 50Wh more than the PowerTube 750 version we've had for the last 2 model years.
Having been provided with the final launch materials, the reason is now obvious.
The new Bosch PowerTube 600 weighs the same as the older PowerTube 500, but a full 1.4lbs (635g) less than the 625, shaving over half a kilo from a bike without the normally associated significant cost increase.
This weight saving carries through to the new PowerTube 800, which comes in at almost 1lb (453g) less than the 750Wh and only 0.6lb (272g) heavier than the older 625Wh version.
For just an 8% weight increase from a 625Wh to a 800Wh battery nets riders a whopping 28% increase in range!
Note: Due to differences in mounting assemblies, it will not be possible to upgrade early generation Smart System bikes using the 500Wh, 625Wh and 750Wh PowerTube batteries to use either of the new 600Wh or 800Wh variants.
Here's the full PowerTube Battery line-up for 2025.
Any changes to the Bosch ABS system for 2025?
Bosch eBike ABS Pro
Pioneers of ABS systems for electric bikes in partnership with Magura, Bosch have updated the Bosch eBike ABS system with a new Braking Statistics function accessible through the Bosch eBike Flow App.
This new function allows riders (particularly mountain bikers) to look back through their "braking history" and see visualisations of of the number and distance of braking events, as well as those where ABS was or wasn't activated.
The non-Pro version (without the Braking Statistics function) is available from E-Bikeshop on the new 2025 Cube Kathmandu Hybrid EX 800 Crossbar, Uni and Easy Entry frame variants.
Any updates to the Bosch eBike Flow App for 2025?
Bosch eBike Flow App
The central hub of information and the best way to get the most from your Bosch Smart System equipped bike, the Bosch eBike Flow app is available in both Android and iOS format and packs in a ton of features for free (eBike Flow), with a couple of extra's available with a subscription based service (eBike Flow+).
The Bosch eBike Flow app allows riders to lock their ebike system using their smartphone and in conjunction with the Bosch ConnectModule can also offer an audible alarm to warn would-be thieves of its protected status. The Bosch ConnectModule also allows the use of the tracking function in the event of a theft.
As well as the ability to protect the bike while not in use, the Bosch eBike Flow app also ties in navigation to the experience. For bikes not fitted with a Kiox 300 or Kiox 500 display, the phone can be used on its own or paired with the Bosch SmartPhoneGrip to take advantage of Bosch's unique route planning, navigation, activity tracking a Range Control functions.
Note: A one month free trial of the Flow+ version of the app is available for all new bike owners as standard. This can either be extended, or left to return to the free version of the app. 12 months of access to Flow+ is available to riders who purchase the Bosch Connect Module.
What we think of the Bosch eBike 2025 range?
Its great to see Bosch continuing to innovate, especially given the last 24 months of trading performance in the global cycle market.
While there has been a significant amount of "doom and gloom" with many large retailers and some well known brands having folded over that period, key manufacturers like Bosch continuing to innovate and invest in the market offers a great deal of comfort to retailers who've been facing a lot of bad news since Covid-19 faded into the distance.
With Bosch having spent a significant amount of money in R&D bringing these products to market as well as updating a motor which was already regarded as the best performing and most reliable, we can seek comfort in their dedication to the range and its continuance into the future beyond 2025.
