Bosch ebike system, 2015

The Bosch ebike system is available on many mid-to-high range ebikes. Bosch entered the ebike market in 2011, and it has experienced a constant and growing success since then, so much so that sometimes production has struggled to keep up with demand.

Bosch has decided to produce not only motors, but also all the other electrical components of an ebike: batteries, pedalling sensors, displays…Bosch’s range of ebike systems has evolved in time, especially after Eurobike 2013, when new versions have been presented to the public. This is why we have decided to present a review of Bosch’s systems, in order to compare and contrast the various versions available.

Let’s start by making it clear that Bosch does not produce ebikes: it “only” offers its systems (that is: motorbatterydisplay etc…) to ebike producers who decide to set them up on their ebikes. Also, it is not possible to buy a “conversion kit” version of Bosch’s systems.

Bosch’s range of products is based on two lines: the Active Line and the Performance Line. You may still find some ebikes on sale which are based on their older Classic Line, but that is being abandoned by Bosch. If you can get a fat discount on a Classic ebike, then good; but if you want a future-proof system better go for an ebike with an Active or Performance system.

Knowing the differences between these systems will allow you to make a more informed choice. These are generally quite expensive ebikes (starting from about 1500€), so it is important to buy one that is really adapted to your needs.

Bosch Active Line

Drive Unit Active: by “Drive Unit” Bosch means the motor plus the ECU and the sensors. Active Line motors are available in the Drive version (which provide assistance up to a speed of 25 km/h); it has a torque of 48 Nm and weighs less than 4 kg. A series of sensors measure the torque provided by the cyclist, the speed and cadence, 1000 times per second.

Intuvia is the name given by Bosch to its controller with display. Its main function is selecting the desired level of assistance among the following:

  • Turbo: the motor delivers a power which is 225% that delivered by the cyclist
  • Sport: the assistance value is 150%
  • Tour: the motor delivers 100% of the power delivered by the cyclist, therefore doubling it
  • Eco: the motor delivers 40% of the power delivered by the cyclist
  • Off: the motor is off

(Don’t miss at the end of this article the section dedicated to the new Bosch controller for 2015, the Nyon)

Power Pack, that is, the battery. There are two versions of Bosch’s batteries: a 300Wh battery and a 400Wh one. They’re both litihium batteries, working at 36V, with a capacity of 8,2 and 11Ah respectively. The 300Wh battery weighs 2,4kg, the higher-capacity battery weighs 2,6 kg. This picture, taken from Bosch’s website, shows the expected range for each kind of battery and each level of assistance, in case of optimal, normal, or difficult conditions.

Charger: Bosch’s charger weighs 800 grams. It recharges the PowerPack 300 to 80% of its capacity in 1,5 hours, and to 100% in 2,5 hours. For the PowerPack 400, the time needed is slightly longer: 2 and 3,5 hours respectively.

Bosch Performance Line

Drive Unit Performance: the motor of the Performance Line has a torque of 50 or 60 Nm (in case of hub gear or derailleur gear respectively). The weight remains less than 4 kg. As for the Active Line, sensors measure torque, speed and cadence 1000 times per second. The Performance Line motor is also available in a “Speed” version, which can reach a speed of 45 km/h.

Intuvia: the controller display is very similar. What changes are the specifications regarding the levels of assistance:

  • Turbo: the motor delivers a power which is 275% of that delivered by the cyclist
  • Sport: this value goes down to 170%
  • Tour: The motor delivers 110% of the power delivered by the cyclist
  • Eco: 50%
  • Off: the motor is off, though the electronics are on

(Don’t miss at the end of this article the section dedicated to the new Bosch controller for 2015, the Nyon)

Power Pack: batteries available for the Performance Line are very similar to those of the Active Line, with a capacity of 300Wh and 400Wh respectively. Performance Line motors deliver more power than Active Line motors; consequently, the range available is about 10% less, as you can see on this picture taken from Bosch’s website.

Charger: the charger is very similar to the one available for the Active Line, and its performance is the same.

Nyon, the new display and controller

Bosch ebikes sold starting from 2015 can mount a new bike computer called Nyon.

Nyon had already been shown to the press many months ago, but it was not actually available on ebikes sold to the public. We don’t yet know whether Nyon will be available on ALL Bosch ebikes, or (more probably) just on high-end ones.

As Bosch says, Nyon is at the same time a system used to control the functions of the ebike; a navigator; and an entertainment system. over, Nyon connects to the smartphone.

Buttons are placed next to the left handlebar grip, in a way which makes it easy to reach them with your left thumb. Maps are optimized for bike navigation, and can be consulted both in 2D and in a 3D simulation. Nyon can be connected to a heart-rate sensor, allowing you to have access to a whole range of functions conceived for training (for instance, you can define the hear-rate at which you would like to pedal; Nyon will automatically adjust the power delivered by the motor to make you stay within that range). Thanks to the connection to the smartphone, messages and calls are notified on the display, and can be read entirely when the bike is halted.

One of the most interesting characteristics of the Nyon is the possibility to finely personalize the 4 levels of assistance. The display of your smartphone will show curves, corresponding to the 4 levels of assistance. Each curve shows how the motor delivers a minimal assistance at first, which grows as the speed increases and then diminishes gradually. Each curve can be personalized. If, for instance, you generally like the Eco level, but you think it could be more punchy at starts, you can increase the steepness of the first part of the curve.

The navigation system is based on Open Street Maps; the GPS sensor and the elevation data included in the map allows Nyon to calculate more precisely the remaining range offered by the battery. It is of course possible to record tracks, analyze them on your pc and upload them to a Cloud system.

Automatic gear shifting systems

In 2015 Bosch is betting a lot on automatic gear shifting systems. Using the right gear (and therefore having the right cadence) is very important on a Bosch ebike, because it allows the motor to work at a more efficient rate (the motor works at its best with a cadence of 60-70 rpm). This translates into a higher range, and therefore in happier e-cyclists. Sport-oriented or expert cyclists may prefer a manual gear in order to have maximum control on it, but for the majority of the population, especially in a urban setting, a well-working automatic gear shifting system can be useful or even liberating (think about how often you have to change gears in the city). For its ebikes, Bosch has decided to partner with three important actors:

Bosch Shimano

This is actually NOT an automatic gear shifting system; “just” an electronic one. Bosch ebikes can be integrated with the Shimano electronic Di2 gear. The cyclist is still in charge of deciding when to change gears, but the controls on the handlebars don’t actuate a mechanical cable; rather, they send an electric signal to the gear system, which then changes the gear. The integration of the Di2 with the Bosch system means that the Di2 can take power directly from the ebike battery; there’s no need for an extra battery for the Di2 (which you might forget to recharge). The data provided by the derailleur (in particular, the selected gear) will be shown directly on the Nyon display. The new Shimano pieces necessary for the coupling with Bosch are:

This system will only be available on Bosch ebikes with a maximum speed of 25 km/h. The derailleurs which can be used are the following:

Bosch NuVinci

Bosch has also started to collaborate with Technologies Fallbrook, the producers of the NuVinci, a continuously variable and automatic gear-shifting system. In this way, it is possibile to always keep the preferred pedalling cadence. This is not new per se, but the agreement now allows the NuVinci H | Sync to be completely integrated with the Nyon controller, thereby making it not necessary to have a separate controller: the handlebar is therefore clutter-free. The H | Sync system is based on the CAS interface, and will therefore be compatible not only with the Bosch system, but also with other ebike systems.

What does it all mean in practice? You will be able to select (directly on the Nyon) your preferred pedalling cadence (from 30 to 80 rpm), and the automatic gear-shifting system will automatically choose the correct gear, according to the situation. Remember that the Bosch motor works at its best with a cadence of about 60-70 rpm. In this way, you’ll be able to select a 60 rpm cadence and then forget about the rest.

Bosch Sram

Finally, Bosch has also concluded an agreement with Sram, Shimano’s great rival, to integrate the Dual Drive 3 Pulse automatic gear with the Bosch ebike system. Sram’s solution is a combination of an automatic hub gear, with three speeds, and a normal 10-speed rear derailleur. The automatic hub gear changes the gear according to the speed of the ebike (0-8 km/h for the first gear; 8-15 km/h for the second gear; 15 km/h for the third gear).

We will try to have an ebike with one of these systems in test as soon as possible.

Bosch eBike Systems – Flow for everyone

Whether it’s a sporty ride through the forest or a relaxed commute to work. eBikes have become indispensable on our bike paths. In order to be able to adapt the riding experience even better to individual needs and wishes, Bosch eBike Systems has developed an app called Flow. It offers features such as additional theft protection and provides riders with all the relevant information they need via the ride screen. During the ride, speed, distance, altitude, weather as well as fitness and performance data can be viewed without having to take your hands off the handlebars. To ensure that this new dimension of cycling is accessible to everyone, Bosch eBike Systems called in our UX experts. Together, we tested and further developed the app in terms of its accessibility.

Inclusive understanding for sustainable products

In order to ensure barrier-free use of the eBike Flow app, we first tested whether the app complies with the Web Content Accessibility Guidelines (WCAGs). The WCAGs represent the international standard for digital accessibility and are particularly relevant to future-proof products due to the Barrier-Free Accessibility Act. Depending on which criteria apply to the product, which disabilities are in FOCUS, and which level of compliance is targeted, the scope of the disabilities criteria will vary.

Step-by-step towards accessibility

A central component of our preliminary analysis was the understanding of the users and their disabilities: how do vision impaired people people participate in road traffic? And which assistance systems are used in different situations? As a result of this preliminary analysis, we decided together with the Bosch eBike team to FOCUS on achieving compliance level AA under the WCAGs and on optimizing the design aspects of the interface. With UXMA’s support, Bosch eBike Systems has been able to accelerate its adoption of the topic of accessibility and implement the accessibility standards immediately in the project.

Testing Usability

To ensure that barrier-free use is guaranteed, the app was then assessed by UXMA’s Accessibility Expert. The resulting Accessibility Conformance Report (ACR) provides detailed information about the extent to which accessible use is possible and which components and patterns need to be improved. Barriers were identified, for example, in animations and videos, in color perception, and in the consistency of layout and operation. These identified barriers were then discussed in detail with the team in order to jointly develop the best results for accessible app use for people with disabilities.

We believe that to become established as a user experience requirement, a solid understanding of the WHY and HOW of accessibility is needed. This understanding was triggered by UXMA with the help of team talks, trainings and QAs.

  • Assistance in getting started with the topic of accessibility
  • Review and application of WCAG conformance level AA
  • Creation of an official Accessibility Conformance Report (ACR)
  • Support for design teams during accessibility optimizations
  • Accessibility training for designers

Accessibility is no longer just a nice-to-have. and more organizations are asking themselves how suitable their applications are for users with disabilities and which legal requirements must be met. Do you want to explore this question together with us? Feel free to contact us!

Bosch Gen3 Gen2 motors

As far as e-bike drive systems are concerned, Bosch eBike Systems has established itself as the market leader throughout Europe. Founded in Stuttgart in 1886, Bosch today is primarily active as an automotive supplier and as a manufacturer of household appliances and electric tools. In 2009, the company entered the booming e-bike market with the founding of “Bosch eBike Systems”. In the same year, the first e-bike drive system was presented at the Eurobike bicycle trade fair. In 2011, the first Bosch e-bike drive went into serial production. and proved to be extremely successful. Over time, other Bosch e-bike drives were added. Today, Bosch systems are installed by over 50 leading European bicycle brands in their e-bikes.

About Bosch Gen2 and Gen3 e-bike motors

At the moment there are at least 4 or 5 different e-bike drive generations from Bosch: After the proven Bosch Classic Line (Gen1), Bosch launched 2 new drive systems in 2014, namely the Active Line and the Performance Line (both also called Gen2). With these two product lines, Bosch wanted to address different e-bike target groups: The Active Line (also available with coaster brake) was aimed more at comfort-oriented leisure and everyday cyclists, while the Performance Line with its powerful drive was primarily aimed at sporty riders. A special feature of the Active Performance Line drives is the Bosch 3-sensor concept, which measures pedalling force, cadence and speed 1,000 times per second, so that you always get the optimum pedalling assistance. By the way, all Bosch e-bike drive units are mid-mounted motors.

In the 2016 model year, Bosch presented the Performance Line CX. the top model of the Bosch Performance Line series, which was especially designed for use on e-mountain bikes. The third generation (Gen3) followed in 2018: A revised version of the classic Active Line and the new Bosch Active Line Plus. In the meantime, there is already the 4th generation of Bosch drives called Bosch Gen4 / model year 2020. Since Bosch motors from Gen4 onwards are equipped with integrated anti-tuning software, we have a separate section in our shop for Bosch Gen4 e-bikes (Bosch Gen4 motors). Quite new is the Bosch Smart System from 2022, for which we also have attractive tuning solutions in our shop.

This section only deals with tuning tools for Bosch Gen2 and Gen3 motors.

Attention: Firmware version with anti-tuning detection

From firmware version 1.8.4.0 onwards, the anti-tuning detection is also included in e-bikes with Bosch Gen2 and Gen3 drives. For affected Bosch Gen2 and Gen3 e-bikes, tuning tools for Bosch Gen4 motors are required!

Bosch Gen 2 motors

Bosch Active Line:

25 km/h / max. torque 48 Nm / available with derailleur or hub gears / with optional coaster function for the hub gear version.

Bosch Performance Line (MY15/20):

25 km/h (or 50 km/h in the Speed variant) / max. torque 63 Nm / max. pedal assistance 275% / support up to max.cadence: 120 rpm.

Bosch Performance Line CX (MY15/20):

25 km/h / max. torque 75 Nm / max. pedal assistance 300% / support up to max. cadence: 120 rpm.

Bosch Gen 3 motors

Bosch Active Line 2018:

25 km/h / max. torque 40 Nm / max. pedal assistance 250% / support up to max.cadence: 100 rpm.

Bosch Active Line Plus:

25 km/h / max. torque 50 Nm / max. pedal assistance 270% / support up to max.cadence: 105 rpm.

Bosch Performance Line (MY20):

25 km/h / max torque 65 Nm / max pedal assistance 300% / support up to max.cadence: 120 rpm.

A small note from our side: As far as the allocation of the individual motors is concerned, opinions differ somewhat. Some experts classify the Bosch Active Line as Gen2, some as Gen3. Other experts, on the other hand, classify only the Active Line Plus as Gen3 in the narrower sense. In this context, however, this is irrelevant, as the same tuning tools work with all the motors listed. regardless of whether they are assigned to Gen2 or Gen3. Only if the Gen2 or Gen3 drives are equipped with a firmware version from 1.8.4.0 onwards you need tuning tools specifically for “Bosch Gen4”.

Gen3: Bosch Active Line Plus Active Line 2018

For the 2018 season, Bosch eBike Systems presented two new drive systems, namely a revised version of the Active Line as well as the new Active Line Plus. often called the Gen3. Compared to the previous model, the new Active Line motors were more compact, lighter and, above all, quieter. This was made possible in particular by a newly developed gearbox that ensures particularly smooth and harmonious energy development. Another advantage of the new gearbox is that both drives can be used practically like normal bicycles without the motor. so there should be virtually no more motor-related pedalling resistance.

The Active Line 2018 was designed for everyday use, i.e. for rides in the city or on flat terrain (torque 40 Nm / weight 2.9 kg). The Active Line Plus, on the other hand, is somewhat more powerful and also well suited for use in hilly terrain or for longer tours (torque 50 Nm / weight 3.2 kg). According to our information, both drives are compatible with all current Bosch displays as well as with derailleur and hub gears.

All tuning products for Bosch Gen2 also work with Bosch Active Line Plus motors (Gen3). For this reason, we have combined Bosch Gen2 and Gen3 tuning tools.

Can Bosch motors of the 2nd and 3rd generation be optimised?

Yes, there are now a large number of highly recommended tuning solutions for Bosch Active and Performance Line as well as CX Line drives (Gen2). The tuning tools also work with the Bosch Active Line Plus (Gen3). You can find the best tuning tools in our shop.

Here we show you manufacturers who offer tuning tools for Bosch Gen2 and Gen3 e-bike motors:
