E-bike tuning - for e-bikes/pedelecs with GIANT 2015/2016


YAMAHA/GIANT - For some years now, the bicycle manufacturer GIANT has been producing its own e-bike motors. The basis for this are drives from YAMAHA, which are modified with their own software and installed exclusively in GIANT e-bikes and pedelecs under the name "SyncDrive". The SyncDrive Core was the first mid-motor from this series and now runs under the name GIANT 2015/2016.

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 the GIANT 2015/2016.

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 the GIANT 2015/2016.


At SIP Scootershop we offer the following tuning modules for the GIANT 2015/2016:

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 small boxes contain a chip, are installed invisibly under the engine cover and clamped between the sensor and the control unit. The module 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.
