E Bike Tuning for Bosch (Intuvia and others)

In 2021, Bosch introduced its new 4th generation motors with the Bosch Smart System. By acquiring a bike with this system early on, we were able to achieve a breakthrough with our e-bike tuning as early as February 2022, allowing riding without the 25 km/h speed limit. We are always at the cutting edge and, thanks to our many years of experience, can also offer solutions for new systems like the one from Bosch.

Due to the global "chip crisis" and "supply shortage" caused by the pandemic, we were only able to start series production after several months. This allowed us to thoroughly test our modifications. By the time sales began, we had completed well over 3,000 km of test rides and were able to ensure that everything functioned perfectly.

Thanks to our extensive expertise and intensive development phase, we are now able to offer sophisticated tuning solutions for the Bosch Smart System. These include both pedelecs with rim magnets as well as those with magnets on the brake disc or spoke.

We introduce: The bikespeed display for Bosch Smart System bicycles

The name of our products already contains the designation RS for "Real Speed". This refers to the special comfort of our advanced solutions: even with the tuning module activated, the actual speed is displayed on your e-bike’s speedometer. With the Bosch Smart System, however, this is no longer easily possible on an original Bosch display or via the Bosch Flow app based on our current technical understanding. Nevertheless, we have fulfilled the expectations associated with the name bikespeed-RS: we have used all our expertise to develop an alternative speedometer for pedelecs with the Bosch Smart System to work with our chip tuning.

This can simply be snapped onto the existing or retrofitted mount of the Kiox 300 / Kiox 500 and offers a comparable range of functions to the original Bosch display. Visually, our in-house development is also extremely close to the original. The bikespeed display is operated via the LED Remote or the System Controller with Mini Remote already installed on your handlebar. The Purion 200 can also be used for operation. However, the Purion display itself cannot be used to show correct data due to the aforementioned limitations. But you can read all correct values on the bikespeed display.

Despite being an add-on, our display provides you with all the essential functions for your ride: you can not only view your actual riding speed, but also all other important information such as the battery charge level and the selected motor support level. Additional data includes cadence (pedaling frequency), calorie consumption, trip distance, total distance, ride time, as well as average and maximum values.

You can combine the bikespeed display with all of our offerings for Bosch Smart Systems. This applies to bikes with rim magnets as well as those with brake disc or spoke magnets. The bikespeed display is multilingual and optionally supports the display of imperial units. It also automatically adjusts brightness to ensure you’re not dazzled in the dark and can still read everything clearly during the day.

Can I also use bikespeed-RS tuning without bikespeed display?

The bikespeed-RS tuning for the Bosch Smart System was designed so that it removes the 25 km/h motor support limit even without our display. This means you can ride your bike with the extended functionality even if, for example, you forget your device at home.

Of course, you can switch off the bikespeed-RS as usual using a simple key combination and then use your pedelec normally.

Spoke magnet, brake disc magnet or rim magnet?

The new 4th and 5th generation Bosch motors with the Smart System are available with two variants for speed detection. One method is well established and has long been used on almost all pedelecs: the speed is measured using a magnet on a spoke or on the brake disc of the rear wheel, with a sensor placed nearby.

In addition to this well-known method, Bosch has introduced a completely new option for its Smart System: the so-called rim magnet is attached to the valve of the rear wheel rim or inside the tire on the rim, while the sensor is integrated into the motor. Although tuning e-bikes with a rim magnet initially posed a special challenge, we were able to develop a suitable solution for this Bosch variant as well. With the bikespeed-RS, it is now possible to unlock the motor power.

Motor software versions for rim magnet tuning

At the end of 2023, Bosch released an update of the motor software to version 9.13.0. As a result, many —if not all— available rim magnet tunings became incompatible. However, we found a solution for the new motor software as early as December 2023, which we have been offering with new hardware since the following March. Naturally, we thoroughly tested this new solution beforehand so that our customers can use it as usual without any issues or error messages.

In April, Bosch released another update to motor software version 11.13.0, which once again led to compatibility issues. For bikes without a rim magnet, a solution could be found quickly through adjusted software. However, rim magnet tunings required another hardware modification. Thanks to our experience, we were able to implement the change much more quickly this time and soon offer our modifications for all variants and software versions. For bikes with rim magnets, however, we recommend exercising particular caution with updates.

To receive the correct modification for your bike, it is important to select the appropriate variant for your pedelec when placing your order. This is crucial because the different methods of speed detection require different hardware in the tuning: rim magnet, brake disc magnet, or spoke magnet. Our shop will assist you in making the right selection.

For bikes with ABS we currently have no tuning on offer.
