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


BROSE - Anyone who can look back on 110 years of engineering experience is unlikely to fail if they want to get into the business of drives for e-bikes and pedelecs. BROSE has been extremely successful in this market segment since 2014 and the drives from Berlin are now installed in over 50 brands worldwide. They are considered to be particularly powerful, light and quiet. A special feature is the fact that the housings are available in aluminium or magnesium.


The name of the manufacturer is usually written on the housing of the drive. In the case of BROSE, in any case, the name cannot be overlooked. You should also be able to find the exact name of the motor in the data sheet supplied. There are four different drives from the Berlin manufacturer:

  • BroseDrive C: 250 W / 50 Nm / up to 25 km/h

  • BroseDrive T: 250 W / 70 Nm / up to 25 km/h

  • BroseDrive TF: 250 W / 90 Nm / up to 45 km/h

  • BroseDrive S: 250 W / 90 Nm / up to 25 km/h

The following list shows you the manufacturers whose modules we at SIP Scootershop offer for BROSE 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 motor and are suitable for many BROSE motors.

The Italians are the only manufacturers of e-bike and pedelec motors who also offer tuning modules. POLINI modules are installed directly on the motor and are not visible from the outside. POLINI modules can be used with all BROSE drives.

E-bike and pedelec tuning from Lower Franconia. The so-called Badass Box is not installed on the motor, but is simply attached from the outside and works smoothly with all BROSE motors up to 25 km/h.


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


At SIP Scootershop we offer the following tuning modules for BROSE motors:

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.
