RedPed 3 for Bosch (Gen2, Gen3 & Gen4)

RedPed 3 for Bosch (Gen2, Gen3 & Gen4)

Probably the most comprehensive and best tuning tool for Bosch e-bikes ever, also compatible with Bosch Gen4 drives!

This tuning tool for Bosch e-bikes impresses with an extremely high range of functions, so that you can optimise your vehicle in many different ways. The RedPed 3 is a tuning module that must be permanently connected to the motor. The tuning settings can then be set conveniently using the EBT app ("RedPed - E-Bike Tuning App"). The most important core function of the RedPed 3 is, of course, the removal of the speed limit, whereby the level of maximum motor assistance can even be set to a value of one's own choosing. It is also very practical that you can set an activation code via the app, with which the tuning can be switched on and off via the control buttons of the e-bike. For this reason, it is not absolutely necessary to take the smartphone with you every time you ride the bike. In principle, it is sufficient to make the desired settings once.

Note: If you need a crank puller to open the motor, you can purchase a low-priced crank puller in a special offer here with the purchase of this module.

Important, please note: The Bosch Gen4 e-bike drives (2020/2021 generation) are equipped with integrated anti-tuning software (this also applies to Bosch Gen2 & Gen3 drives from May 2019 with software version 1.8.4.0 or higher). Although the RedPed module is characterised by a very low susceptibility to errors, we would strongly recommend the following tips to permanently avoid detection by the anti-tuning software:

1. do not set the maximum supported speed higher than 32-33 km/h.

2. if you ride longer distances with tuning activated, you should slow down every now and then, at least for a short time.

If you follow these tips, it is almost impossible for the anti-tuning software to recognise the tuning. However, there can never be a 100% guarantee that the anti-tuning software will not recognise the tuning after all. There are even cases in which corresponding error messages occur without any tuning at all.

If you wish, you can also set the max speed higher than 33 km/h (up to 45 km/h) via the app, but we strongly advise against this option! If an error occurs as a result of the assistance speed being set too high, we cannot offer any support and an exchange is also excluded.

Connectivity: The RedPed app has the advantage that it can display extremely diverse parameters while on the road - even more than conventional Bosch displays can offer. So it makes perfect sense to attach the mobile phone to the handlebars while riding, e.g. using special smartphone holders.

The RedPed 3 module has all the functions and advantages that were already available in the previous versions. However, there are now a few improvements that make the RedPed 3 the best model of the entire RedPed series so far. There is hardly any other tuning tool for Bosch e-bike motors that offers such a wide range of optimisation options - with this module you can really get the best out of the Bosch drives!

RedPed 3 – Functions & Features at a glance

• Removal of the speed limit.
• Setting the maximum speed to a self-selected value from 15-33 km/h. Optionally, the maximum speed can also be increased up to 45 km/h (Note: With Bosch Gen4 drives, you should not set the Max Speed to over 32 km/h, otherwise the integrated anti-tuning software could kick in).
• Set individual activation code: The tuning can be switched on and off via the EBT app. Alternatively, you can also set a code with the app to activate/deactivate the tuning using the control buttons on the e-bike.
• Even when tuning is active, the e-bike display shows the speed and distance travelled correctly.
• Even after the module has been removed, the total kilometre reading is displayed correctly.
• Tuning activation: Set a key combination with which you can activate and deactivate the tuning via the control elements of the e-bike. This means that you no longer need a smartphone to activate/deactivate the tuning.
• "Speed Offset": You can reduce the speed shown on the display to up to -15 km/h. Example: If you set a value of -10 km/h and drive at a speed of (e.g.) 35 km/h, the display will only show a speed of 25 km/h, etc.
• "Visibility": Here you can set how long the RedPed can be found in the app after the e-bike has been switched on. This prevents unauthorised access to the module.
• "Troll mode": In this mode, the e-bike switches off after a self-defined time (10-60 sec) or restarts if no smartphone has connected to the module within the defined time. This function is not a real theft protection, but it can be used to annoy people who have access to the e-bike but are not actually supposed to ride it.
• "Workshop mode": If this mode is set, the CAN BUS data is not manipulated by the RedPed. Very practical if you have to take the e-bike to the workshop.
• "Split speed at": Here you can set how the speed is to be split.
• Set the PIN to protect the RedPed from unauthorised access.
• Set module name.
• The wheel diameter can be entered.

Data display via app

With the EBT app, you can not only define the tuning settings, you can also display an unusually wide range of parameters. It is possible to visually adjust the displayed data according to your own preferences (change colours of certain values, hide values, etc.). Here is a selection of the most important data:

• Tuning status (on/off)
• Support level
• Speed (current, average, maximum in one line)
• Crank speed in RPM (actual, average, maximum in one line)
• Crank Torque in Nm (Current, average, maximum in one line)
• Rider power in watts (Current, average, maximum in one line)
• Engine power in watts (current, average, maximum in one line)
• Battery charge level in percent
• Range in km
• Driving time in minutes
• Charging cycles (number)
• KCAL of the driver
• Distance in km (current distance travelled)
• Mileage of the RedPed

RedPed 3 for Bosch - innovations compared to previous versions

-The module is even smaller.
-Lower power consumption.
-There are no more jerks when using the SmartphoneHub or Cobi display.
-"Tuning Timer": With this completely new function, the tuning is automatically deactivated after a self-set time.
-"Unlock Max Speed": With the RedPed 3, the maximum supported speed can normally be set to a level of 15-32 km/h. You can also increase the maximum speed up to 45 km/h, but this function has to be activated separately via the app. The background to this is that Bosch motors from Gen4 onwards are equipped with special anti-tuning software and it cannot be ruled out that tuning could be detected at maximum supported speeds above 33 km/h.

Please note: If you have a Bosch Gen4 motor or an older Bosch drive with anti-tuning detection (from software version 1.8.4.0), and still unlock the Max Speed to 45 km/h, you do so at your own risk. If the manipulation is detected in this case (error 504), there is no more support from the manufacturer.

RedPed 3 for Bosch - Installation & Functionality

The RedPed 3 is a module that needs to be connected between the motor and the speed sensor as well as between the motor and the display. After installation, the module measures the actual speed and generates its own speed signal for the motor control unit. Since the module generates a lower speed, the preset speed limit of the engine is outsmarted. Due to this operating principle, the engine control unit will calculate various values incorrectly, such as the total distance. However, the values are corrected by the RedPed and transmitted to the display so that the correct data is still shown.

Communication between RedPed and smartphone works via Bluetooth 4.0

RedPed 3 Instruction

You can find detailed installation and operating instructions here.

Tip: Bosch Smart System e-bikes (BES3) can be easily recognised by the charging cable plug, among other things.

SQUARE plug = Bosch Smart System BES3 (Gen4) + Bosch Gen5:

ROUND plug = Bosch Gen2, Gen3 & Gen4:

If your Bosch e-bike charging cable has a round plug (as shown above), you have selected the correct tuning module. If your Bosch e-bike does not have either connector, you either do NOT have a Bosch e-bike or an e-bike with the old Gen1 drive (Classic Line).
