BOSCH: The Bosch engines were one of the first mid-mounted engines to be produced on a large scale. Thanks to their reliability and high performances they become very popular to the point that today they are the engines of choice for more than 50 e-bike manufacturers. It is not a surprise that the first tuning to be produced were designed to unlock these Bosch motors.
The first engine produced was the Bosch Classic Line (Gen1) up to 2014. The Gen2 engines Active Line and Performance Line (produced from 2014) and the Performance Line CX (from 2015). The Gen3 engines Active Line Plus were first produced in 2017. The latest Gen4 engines Performance Line (+ CX) have been produced since 2020 and do have an integrated anti-tuning measure. All Bosch engines (Gen2, 3, and 4) from Firmware version 1.8.4.0 onwards do require a tuning kit that can override the Bosch anti-tuning measures.

In 2022 Bosch released the new Bosch Gen4 Smart System which Bosch call it the "BES3" and stands for "Bosch Ebike System 3". For the general public, the new Bosch Smart System is also known as the Bosch Gen5. The main focus on the development of the BES3 was to expand into the digital e-bike smart networking system. In fact, the new engine is compatible with the" eBike Flow App" with the KIOX 300 display.
ENGINE PLUGS COMPATIBILITY: The new 2022 Bosch Smart System comes with completely new engine plugs which are rounded in shape. The previous generation of Bosch engines does have squared engine plugs and therefore are NOT compatible with the new Smart System motor ports.
MAGNET ON THE AIR-VALVE: As for today, there are no tuning available for the Bosch System with the MAGNET on the AIR-Valve. Surely, the tuning manufacturers are working on a solution for this system. Just subscribe to our FaceBook group for updates on the release of tuning compatible with the magnet on the air-valve.

Another excellent tuning is the VOLspeed which has been on the market for very long time and are well known for their reliability and unique features. Indeed, with the VOLspeed apart from setting up the maximum assisted speed to improve battery consumption you can also adjust the engine behaviour for a smoother engine engagement and disengagement and thus improved handling capabilities on technical terrains. All this features can be programmed via the keys on the display.
SpeedFun was one of the first manufacturer of tuning on the market. For the Bosch motor we do have the SpeedFun advanced Bosch tuning which retains the speed accuracy for speeds even above the 60 km/h and can be activated and deactivated by a pressing a key sequence on the display.
Then, there is ePlus the most advanced Bosch tuning on the market. Indeed, thanks to the phone app you can switch off and lock the tuning, lock the motor (theft protection), and set the torque for each engine power mode.
The badassBox is a contactless tuning box that simply slide over the speed sensor and it is installed / removed in just a few clicks. badassBox Bosch models are compatible with several speed sensor shapes and speed sensor location on the rear sub-frame. Please check your bicycle speed sensor setup before choosing the badassbox model suitable with your bike configuration.
the MBIQ is a tuning that operates via a micro-controller processor. The MBIQ tunings are the smallest tuning if compared to the other tunings on the market. Due to this property, the electronics that operates the tuning are directly incapsulated into the speed sensor which makes the tuning completely invisible. The MBIQ are programmable and thus the tuning can be activated and deactivated and also programmed for setting up the max speed assist by just following a sequence of wheel rotations.

TUNINGS FOR BOSCH SMART SYSTEM BES3
The Bosch Smart System is a more complex and advanced drive unit than its predecessor which does not allows to program the tuning to communicate with the engine software as for previous engine. For this main reason, the displayed speed will be inaccurate with the basic tuning method. If the accuracy of the speedometer is important for you then the only tuning solution available is the SpeedBox B.tuning version which display the correct travelled speed directly on your mobile phone.
