E-bike tuning - for e-bikes/pedelecs with SPECIALIZED motor


SPECIALIZED - A motley crew of passionate cyclists began making tyres in the USA in 1974, because there was a great shortage of high-quality tyres. A few years later, SPECIALIZED successfully built entire mountain bikes and made a name for themselves beyond the States. This was followed by racing bikes, touring bikes and finally e-bikes or pedelecs.


SPECIALIZED does not offer its own drives, but installs BROSE motors in its e-bikes and mountain bikes. The software of the drives is adapted to the respective bike so that an optimal interaction of motor and material is achieved. In the case of SPECIALIZED, you don't have to look up which motor your bike has, but the model of the e-bike itself is decisive. At the moment, tuning is available for the following e-bikes:

- Speedbox 1.0: All Brose SPECIALIZED drives
- Badass Box 4 Specialized Set: Turbo Levo (pre 2019), Turbo Vado, Turbo Kenevo (pre 2020), Turbo Como
- Badass Box 4 Specialized Set Turbo Levo 2019: 2019 & 2020 Turbo Levo, Turbo Levo SL, Turbo Creo SL, 2020 Turbo Kenevo

The following list shows you which modules we at SIP Scootershop offer for SPECIALIZED motors:

The manufacturer from the Czech Republic has gained experience in the production of tuning chips since 2014. Its modules are installed directly on the engine and are suitable for all BAFANG engines depending on the year of manufacture: The Speedbox 1.0 can currently be used for most SPECIALIZED bikes.


The Czech manufacturer builds tuning modules for the engines of many well-known manufacturers. They are characterised by clever functions such as a chip lock or the "Still On" mode. These interesting modules are also available for some TQ engines.

E-bike and pedelec tuning from Lower Franconia. The so-called Badass Box is not installed on the motor, but simply attached from the outside and works with many e-bikes from SPECIALIZED.

These small boxes are plugged onto the sensor of the bike or pedelec and now this tool halves the transmitted speed, doubling the motor support. It is a wireless device that can be removed again in no time. The manufacturer Badass is the market leader here.

These modules contain a chip and cables with connectors. They are installed invisibly under the engine cover and clamped between the sensor and the control unit. Many modules can even be switched on or off via the display while driving. The latest modules, such as the Speedbox B, also have integrated app control via Bluetooth. The control and also the reading of the motor data can be done with the smartphone. However, tools are required for installation and removal. In the following, we will go into more detail about these modules.

The motors are controlled by a speed pulse that tells them how fast a pedelec or e-bike is travelling. If the pulse reaches 25 km/h, the motor switches off. However, if only every second signal of the impulse comes through, 50 km/h can be reached, because the motor is "fooled" into thinking it is travelling at a different speed. With cheap modules, the speedometer then simply displays half the speed.

More sophisticated chips are more advanced: they halve the impulse only from 23 km/h or, in some drives, they are directly connected to the data transmission between sensor and motor, so that the speedometer always shows the correct values. The most modern tuning modules, for example from VOLspeed or Speedbox, even display the total kilometres driven and average speeds correctly.

However, the software version of the bike and pedelec must also be kept in mind. A carelessly installed update from the manufacturer can abruptly end the tuning pleasure. Be careful, because the motor manufacturers and tuning experts are constantly playing a cat-and-mouse game.
