Bosch reveals e-bike components for model year 2021

Bosch eBike Systems has just presented its innovations for the next model year, including a new onboard computer, software updates for various drive systems, a function extension for the Bosch Performance Line CX and a new eBike design study.

If Bosch has its way, e-bike riding will be noticeably smarter in the future, thanks to the updated Nyon onboard computer that connects with Bosch digital e-bike products. The onboard computer automatically synchronises ride data with the eBike Connect app and the associated online site. During the ride, the Mini-PC can be controlled using a separate control unit. When on the move, the 3.2-inch colour display shows the user the way, provides fitness data and informs the rider how far they can get with the selected assistance under the geographical conditions or when a different mode would favour range.

As a premium function, Bosch also offers the prospect of additional digital protection against theft and promises that other connectivity functions are to follow in the future. The upgraded Nyon will be available for retrofitting from specialist dealers from autumn and is compatible with all drive systems from the model year 2014.


From this summer, software updates for Bosch’s Cargo Line, Cargo Line Speed, Performance Line Speed and Performance Line CX will also be available for the 2021 e-bikes. According to the manufacturer, new features include a maximum torque of 85 Nm and further developed software, which should result in “an even more natural and dynamic driving experience”. According to Bosch, the increased torque provides a plus in performance, which is more noticeable at a low cadence.


For the Cargo Line and the Cargo Line Speed with support of up to 25 kph and 45 kph (speed pedelec version) respectively, the update should make itself felt, among other things, with easier starts on inclines and faster acceleration with heavy loads. Also in the Performance Line Speed (up to 45 kph), the 85 Nm provide more thrust and more dynamic driving experience. According to Bosch, this applies to all drives, especially to the low pedalling sequences. However, in this case, only users of 2021 model year drives can benefit from the update, retrofitting is not possible.


In contrast, the software update for Bosch’s Performance Line CX is even more comprehensive and can be retrofitted from the model year 2020. In addition to the 85 Nm torque, the drive system, which was developed for sporty applications, has several new features that will benefit mountain bikers off-road. These include an Extended Boost, which provides short-term assistance over difficult stretches of road, or the further developed e-mountain bike mode, which is designed to make starting on rough surfaces noticeably more sensitive. The package is supplemented by new sensor and engine control functions that, as Bosch has just announced, “will provide support in the future even more dynamically and naturally in an extended cadence range.”


The new product offensive is supposed to give Bosch eBike Systems an aesthetic of the future look of e-bikes. Here, the manufacturer is picking up on the trend toward integrating system components increasingly seamlessly into the bicycle design. With the eBike Design Vision, Bosch wants to set new standards in this respect and provide the impetus for the pedelec design of the future.


In the sporty urban bike, the drive system merges with the carbon frame and handlebars to form a single unit. Lateral cooling channels in the frame generate the necessary “cooling effect” for the Performance Line CX drive while riding. Bosch’s PowerTube 625 battery is integrated into the down tube and can be removed for charging. The new Nyon onboard computer is embedded in the middle of the handlebars. The control unit of the onboard computer and the two brake levers also form a visual unit with the black handlebars.


“Our aim in developing the eBike Design Vision is to show what is already possible today when it comes to functional design integration and investigates where the journey might take us in the future”, says Claus Fleischer, CEO of Bosch eBike Systems.

Online Course, Trainings and Industry 4.0 Skills at DIYguru Learning Platform

  1. For Students:ITI / Diploma / B.Tech / M.Tech. / M.S. Research (Mechanical, Electrical, Electronics & EEE Branch)

    FUNDAMENTALS: For First & Second-year students, who are new to science and engineering and are looking to boost their CV / Resume to stand out of the crowd in getting Internships and preparing base for making their future in Automotive & Product Development Industry, the best strategy will be to go with Fundamental Job oriented Certification Courses which includes Fundamentals of Automobile Engineering, Fundamentals of Python for Mechanical Engineers, Motorcycle Engineering Fundamentals, Electrical Machine Fundamentals Training, MATLAB Fundamentals & Additive Manufacturing Fundamentals.

    INTERMEDIATE: For Third-year students who are planning about making their career through Campus Placements in Automotive (Original Equipment Manufacturers – OEMS’s & Electric Vehicle) & Product Development Industry the best strategy, if they have cleared their Job oriented Fundamental DIYguru Certification Courses which we have recommended above for sophomore students would be to go with the Job oriented Electric Vehicle Engineering Nanodegree Program, Vehicle Dynamics, MATLAB, CATIA / Solidworks for CAD and ANSYS – CAE for structural analysis and MSC Adams for Multibody Dynamics Analysis like Suspension and other moving automotive body part and finally Automotive Sketching to boost your knowledge of concepts and software required for Automotive Industry and OEM’s, This will also unable you to boost your resume. Third years is considered vital for your career growth and you can make the best use of time by adding as many certifications in your resume as possible to stand out of the crowd.

    ADVANCED: For Final year students, as they are about to appear for Mechanical Engineering companies interview mainly Automotive / Automation & Product Manufacturing companies, it is best suggested to go withJob oriented Advanced Electric Vehicle Engineering Course and Battery Management System Course if they have already gone there thinking about making their career in EV sector which is growing exponentially and is about to generate 25 lakh jobs by 2025. Electrical & Electronics Engineering students along with Electric Vehicle Fundamental & Advanced Module should go for added Labview Course as well as Specialization in DATA Analytics with Python to have a firm understanding of the subject and open a wide variety of career option in Industrial automation (Industry 4.0)

    For students who have passed out from Engineering / Technology / ITI / Diploma background and are looking to enter into Automotive or Product manufacturing/development industry making sure that they land a job after doing DIYguru Job oriented course.The best use of this platform would be to go with The Job Guaranteed Program or the Job Assistance Program which will enable you to go extensively through the modules to be completed in a particular time frame.

    For Professionals

    For Entrepreneurs who are looking to develop an electric vehicle from beginning till the end of the Product lifecycle i.e. right from the Planning phase and preparing the basic concept note to Market Research to Designing and Analysis of different Electric Vehicle OEM parts and then simulating the components in different software obtaining thermal and fatigue profiles and finally rendering the finished prototype and putting it into manufacturing phase, we have prepared a bundled Industry 4.0 pack which you can buy here – Industry 4.0 Course Package consisting of all required courses with lifetime access.
