MTT SmartChip “Switch”: Chip for Bosch Smart System (BES3)
The MTT SmartChip "Switch" is a practical tuning module for removing the 25 km/h speed limit for e-bikes with Bosch Smart System drive without display. In contrast to the MTT SmartSensor ("MTT SmartSensor"), the MTT SmartChip is a convenient module solution that is very compact and easy to install. The module is tiny and, unlike some other modules, fits into even the smallest engine compartment. Once connected, the MTT SmartChip enables you to ride with full motor support, even at speeds well above 25 km/h.
The MTT SmartChip does not require its own battery; the power is supplied by the bike. When tuning is activated, the display will no longer show any real values above a speed of 25 km/h.
The MTT solutions for Bosch Smart System motors are the best products for this motor to date. They generate by far the fewest error messages with the new Bosch motors.
Tip: We recommend the use of GPS-enabled additional devices such as your smartphone if you want to display the correct speed when you are cycling. Suitable mounts for the handlebars are available in our shop.
Important: The MTT SmartChip "Switch" is an extension to the previous MTT SmartChip. The "Switch" version is particularly suitable for Bosch Smart System e-mountainbikes without display. The MTT SmartChip "Switch" has a small cable on the chip which runs back into the chip. If it is disconnected, the original mode of operation is changed (see here): Tuning is activated when the magnet is in front of the speed sensor when the e-mountainbike is started. If the e-mountainbike is switched on and the spoke magnet is not in front of the speed sensor, the tuning is deactivated. This means that tuning can also be activated and deactivated without having a display on the e-bike. If you want to switch this function off again, simply reconnect the two cable ends that were previously disconnected.
MTT SmartChip "Switch" for Bosch Smart System - Compatibility
-This tuning module is compatible with e-bikes with "Bosch Smart System" drive systems, sometimes also referred to as "Bosch Gen4 2022", "Bosch Gen5" or "BES3" ("Bosch development stage 3"). The MTT SmartChip “Switch” is specially designed for Bosch Smart System e-bikes without a display.
-This tuning tool is not compatible with Bosch Smart System e-bikes with a rim magnet. These models can be recognised by the magnet or the speed sensor on the rear wheel valve. In this case, please select the RimBoost.
-Not compatible with Bosch Smart System e-bikes with ABS system.
Attention: Please do not carry out any Bosch updates after installing and using a tuning! Compatibility may then no longer be guaranteed!
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).

Important: Tuning measures on e-bikes and e-scooters mean that they are no longer permitted for use on public roads. Legally permissible use is therefore only possible on private property or - if permitted - in competitions. Driving an e-bike or e-scooter modified by tuning measures on public roads can lead to criminal liability for driving without a license as well as driving without insurance coverage. Tuning measures on the e-bike and e-scooter can lead to a loss of warranty rights and manufacturer warranties. In addition, tuning measures can lead to a loss of insurance coverage and accident victim assistance benefits in the event of accidents. The e-bike (or e-scooter) modified by tuning measures is exposed to an additional load due to the higher speed, which can lead to safety risks.
