Bosch eBike Systems

Company

A 2009 Bosch Start-Up Became an Independent Division Supplying More Than 100 Bike Brands

Bosch eBike Systems started inside the Bosch Group in 2009, showed its first drive at Eurobike 2010 and began series production in February 2011.

Bosch eBike Systems has been a separate division of Robert Bosch GmbH since 1 January 2020 and is led by CEO Claus Fleischer. Bosch does not report e-bike revenue or headcount separately; the group as a whole had sales of 91 billion euros and about 413,000 employees in 2025. Bosch's April 2026 results described e-bikes as an established core business where it invests in technology and service and avoids price wars with Asian suppliers, while the wider Mobility sector's EBIT margin fell to 1.8% in 2025.

Drive units are built in Miskolc, Hungary, where Bosch opened a 20 million euro e-bike drive building in 2011 and set up production and logistics in 2012. A second plant in rented halls at Petrovany, near Prešov in Slovakia, was planned for about 400 staff with production from late 2023; Bosch wound it down from March 2024, saying e-bike demand had not grown as expected and that Miskolc had enough capacity. In January 2026 Bosch took full ownership of MAGURA Bosch Parts & Services, its former service and spare-parts joint venture with the German brake maker Magura.

Bosch eBike Systems will not exhibit at Eurobike 2026. It announced the decision in November 2025 after the German bicycle industry association ZIV, whose board includes Fleischer, ended its cooperation with the Frankfurt show.

Lineup

The Performance Line CX, CX-R, Cargo Line and Speed Share a 100 Nm, 750 W Ceiling

Figures are Bosch ratings as reported by Bosch and trade press. Every unit is rated at 250 W continuous. Hub motor torque is measured at the wheel and does not compare directly with mid-drive torque. A dash means the figure was not confirmed.

The fifth-generation Performance Line CX launched in September 2024 at the same 85 Nm and 600 W as its predecessor, with a patented freewheel that stops gearbox rattle and almost 100 g less weight; BIKE Magazin measured drag with assist off at 9.1 W against 13.8 W for the fourth generation. A free over-the-air update in July 2025 lifted it to 100 Nm, 750 W and 400% support and added an eMTB+ mode, and the CX-R, unveiled in May 2025 to replace the CX Race, shipped with the same figures and a Race mode with longer Extended Boost. Performance Upgrade 2.0, released through the eBike Flow app on 4 May 2026, lets the bike maker allow peaks of up to 120 Nm on the CX and CX-R, with at most 100 Nm in steady output, raises support to 600% below 15 km/h, makes Extended Boost adjustable on a 1-10 scale and adds a Drivetrain Tensioner function from mid-2026.

The June 2025 launch redesigned the Performance Line, 400 g lighter at 2.8 kg, and rebuilt the Cargo Line and Performance Line Speed on CX hardware at 750 W. The Hub Line, shown in June 2026, is Bosch's first hub motor for e-bikes and works with electronic and automatic shifting; it competes with Mahle's rear hubs on city and road bikes. The 2026 Active Line Plus is 17% smaller and 0.5 kg lighter than before, and Bosch claims a 50% lower manufacturing CO2 footprint from part-recycled aluminum and recycled plastics.

Smart System

Batteries From 250 Wh to 800 Wh, Eight Displays and One App Run on the Smart System

The Smart System, launched in 2021, links motor, battery, display, ABS and phone app on one network and takes software updates over the air. The older Bosch eBike System 2 stays in production for some models.

The PowerTube 500 and 750 and the frame- and rack-mounted PowerPack 400, 500, 545 and 800 remain in the range. A 12 A charger built on GaN (gallium nitride) parts, rated at about 500 W and weighing under 1 kg, is due at the end of 2026; it refills about half of an 800 Wh pack in an hour and slows near 80% to balance the cells.

• Displays: Kiox 300 and the 40% larger Kiox 500, both color with navigation; Kiox 400C, a 2.0-inch color screen with up to 1,000 cd/m² brightness, IP55 sealing and a USB-C port, set into the top tube; Purion 200, a 1.6-inch color handlebar unit; Purion 400, a 1.6-inch 320 x 160 pixel eMTB display from 2024; Intuvia 100; Intuvia 200, a 2.4-inch grayscale display from 2026.
• Controls: System Controller set into the top tube, LED Remote, Mini Remote, and the 2026 LED Controller, 65% smaller than the LED Remote with five buttons and a USB-C port.
• App: eBike Flow handles ride modes, navigation with 3D terrain maps, ride statistics, Trick Check jump and wheelie detection on Kiox and Purion displays, and over-the-air updates. A Live Data Interface opens ride data to third-party devices such as Garmin.
• Shifting: eShift automatic and electronic shifting covers Shimano XTR Di2, Deore XT Di2, Deore Di2, Nexus Di2 and CUES Di2, Enviolo and TRP systems, and the Classified Powershift two-speed hub.

ABS and security

Bosch Built the First Production E-Bike ABS and Locks the Bike From the Phone

ABS and theft protection set Bosch apart from motor-only suppliers; several features need the paid Flow+ subscription.

The first eBike ABS went on sale in 2018, and the second generation for the Smart System followed in 2022. ABS reached North America in fall 2023 on bikes from Bianchi, Cannondale and Diamondback, and Tern fits it as standard on Smart System versions of the third-generation GSD cargo bike. Flow+ costs £35, 40 euros or AU$60 a year according to TechRadar, with a one-month free trial, or 12 months free on bikes sold with a ConnectModule.

Bike brands

Trek, Cube, Gazelle and a Dozen European eMTB Makers Build on Bosch

Brands below are named in their own specifications or in trade-press launch coverage. Bosch counts more than 100 brand customers.

US market and legal classes

Bosch Covers EU Pedelecs, US Class 1 and Class 3, and EU Speed Pedelecs

The motor version and its programmed cutoff speed decide the bike's legal class. Bosch eBike Systems Americas has run US sales and service since 2014.

Bosch's 750 W peak sits at the US federal e-bike limit, and its US product pages note that the Performance Line Speed delivers slightly less than 750 W for compliance. The Gazelle Eclipse, launched in March 2024, was the first US bike to pair the Smart System with 28 mph assist, and Trek's Charter+ city bikes, launched in February 2026, use the Performance Line Sport as full Class 3 bikes. In Gazelle's US range the Performance Line is the strongest Class 1 drive, while the Performance Line Speed versions carry a plus sign in the model name. Class 4 E-Bikes covers machines above these limits, a segment Bosch does not supply.

Competition

Chinese Drives From DJI Avinox and Bafang Out-Torque Bosch by 50 Nm

DJI's Avinox launched the M2 and M2S in April 2026 at about 2.6 kg each and lists 16 partner brands, among them Commencal, Forbidden, Unno, Rotwild, Megamo and DJI's own Amflow. Transition Vélo described the Bosch 12 A charger as a reply to the Avinox 12 A charger of 2025, and Performance Upgrade 2.0 arrived a month after the M2S. Bosch matches the Chinese units on weight, with the CX-R at 2.7 kg against Bafang's 2.9 kg M510RS, and adds ABS, theft protection and its own service network. Bafang and Drive Systems compare the other makers' flagship units.
