SpeedBox 1.1 for Bosch Smart System

SpeedBox 1.1 for Bosch Smart System (BES3)

The latest version of the SpeedBox for Bosch Smart System e-bikes - now even less sensitive to tuning detection than ever before!

This tuning tool removes the 25 km/h speed limit of Bosch Smart System e-bikes completely (also compatible with Bosch SX motors). This means that thanks to this tuning tool, you can ride much faster than before with full motor support. That allows you to finally utilise the full potential of your powerful Bosch drive.

Note: With the SpeedBox 1.1, the desired maximum speed can be individually adjusted. However, it is not recommended to set the maximum speed higher than 35 km/h. Setting values above 35 km/h is at your own risk, as the Bosch anti-tuning software could kick in!

Important: The SpeedBox 1.1 for Bosch Smart System (BES3) replaces the SpeedBox 1.0 for Bosch Smart System (BES3).

The SpeedBox 1.1 is a module or chip that must be connected directly to the connectors on the motor.

Please note that your e-bike display will NO longer show correct values (current speed etc.) when tuning is active.

The total distance will be displayed correctly, but only after a countdown (deduction of kilometres) at the end of the ride.

Our tip: If you want to view the correct speed and all riding data during your ride, we recommend this tuning tool in the B.Tuning version, which is also compatible with the practical SpeedBox app. You can then use the app to view the correct riding data on your smartphone display while cycling (you can find suitable smartphone mounts for the handlebars in our shop).

Tuning can be switched on and off

After connecting the chip, the tuning can be switched on and off very easily using the operating buttons on the e-bike.

Tuning can be switched on and off by pressing the WALK button (hold down the "-" button). A short message appears on the E-Bike display to confirm this: "3.5" = SpeedBox ON / "2.5" = SpeedBox OFF. Note: Switching on and off should not be carried out while riding.

On Bosch e-bikes where the WALK function is not available or not activated, tuning can also be activated / deactivated using the -+-+ button combination.

The manufacturer recommends leaving the e-bike switched on for a while after the end of the ride until the SpeedBox has completed the "countdown" (this is indicated by the ride time continuing on the display until it stops and the correct ride distance is displayed) in order to avoid tuning detection.

Setting the maximum speed

The maximum supported speed can be changed by switching the modes from TURBO mode three steps down and then three steps up: eMTB - TOUR+ - ECO - TOUR+ - eMTB - TURBO. The current speed limit is then displayed. You can now adjust the maximum speed by briefly pressing the WALK button or by turning the rear wheel 360°. A displayed speed of 2.5 km/h corresponds to a maximum speed of 25 km/h, 3.0 km/h would correspond to 30 km/h and 3.5 km/h would be 35 km/h, etc. The last displayed speed limit is automatically saved after 15 seconds of inactivity.

A maximum speed of 35 km/h should not be exceeded in order to avoid tuning detection by the Bosch system!

Installation

The SpeedBox 1.1 must be connected to the plug connections on the motor (to gain access to the plug connections, you must temporarily remove the motor cover). To simplify the connection, only original plugs are used in the production of the chip.

Important: The male and female connectors must be connected in the direction of the lock. Do not rotate the connectors during connection!

To activate all the functions of the SpeedBox correctly, it is necessary to enter the menu after the first switching on of your E-Bike after the tuning installation and switch to the circumference of the wheel of your bike.

The SpeedBox does not require its own battery.

Please note: If you want to install the SpeedBox 1.1 chip in a brand new E-Bike, you must first ride at least 10 km on the E-Bike before activating the tuning chip for the first time.

If necessary, the tuning chip can be removed at any time to restore the e-bike to its original condition.

-Performance Line CX (Smart System)

-Performance Line CX Race (Smart System)

-Also compatible with Bosch Performance Line SX motors (Smart System).

-Compatible with Bosch software version 11.13.0 / 12.13.0. Important note: Compatibility with software version 11.13.0 / 12.13.0 is only guaranteed for SpeedBox tuning modules ordered after May 2024. We strongly advise against updating to software version 11.13.0 / 12.13.0 for SpeedBoxes ordered before this date! In this case, the update could lead to incompatibilities with the SpeedBox Tuning.

-Compatible with all Bosch Smart System Displays (for example Kiox 300 or Intuvia 100).

-Not compatible with the SpeedBox app.

-Not compatible with Bosch Smart System e-bikes with ABS system!

-Not compatible with Bosch Smart System e-bikes with a magnet on the valve (rim magnet). Tip: If you have a Bosch Smart System e-bike with rim magnet, please select SpeedBox 1.2.

A few more tips:

-Please do not carry out any Bosch updates after installing and using a tuning tool! Compatibility may no longer be guaranteed afterwards!

-During short breaks, you should keep one foot on the pedal to prevent the "countdown" triggering process from starting so that you can continue riding seamlessly.

For longer stops, you should allow at least a partial "countdown" (kilometre deduction) to run through.

-Do not remove the display from the E-Bike until the "countdown" is complete (the countdown can take several minutes after a long ride).

-Switching the tuning on and off should always be done before and not during the ride.

-The manufacturer recommends not exceeding a maximum speed of 35 km/h.

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 square plug (as shown above), you have selected the correct tuning module (provided the bike does not have ABS or a rim magnet). 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).
