Frequently Asked Questions

The badassBox is attached to the speed sensor of the e-bike and overrides the 16 mph (25 km/h) speed limit - you can expect to reach speeds of up to 25 mph (40km/h) , depending on the bike and gearing. Your displayed speed will be 2 times slower than your real speed. We recommend the use of GPS-related accessories for a more precise data acquisition of driving data (smartphone, bike computer, etc.).

The tuning kit manipulates the speed signal without altering the motor's power relative to pedaling speed. This guarantees a smooth motor control without speed limit interruptions. Depending on a tuning kit, some determine when assistance stops, while others remove the restriction entirely for continuous support. However, the achievable speed mostly depends on the eBike model. Achievable speed can be calculated using a simple formula:

Speed = Cadence [rpm] * Wheel circumference [mm] * Front Chainring Teeth / Rear Chainring Teeth * 60 [min/h] / 1.000.000 [mm/km]

The contactless and wireless badassBox transmits a modified speed signal in order to override the speed limit of your e-bike – without interfering with the motor's electronic circuitry or software. There's no need to open the motor and there is no risk of damaging it, the BadassBox can be fitted or removed in seconds.

If this sensor of your Fazua motor - as shown in the picture below - is located on the chain stay of your bike, then the badassBox4 Fazua is exactly what you need.


If the sensor is not on the chainstay, then the sensor will probably be integrated in the dropout, please see the badassBox 4 Fazua X-Set.

New slim casing with patented snap-lock fastening for even faster mounting and release. Even more robust thanks to a special potting compound from the automotive industry. New electronics for even greater range with a single AAA battery. A quality product designed, engineered and manufactured in Germany.

The delivery includes the following parts:
- one badassBox 4 Fazua
- one badassBox 4 housing cover
- one AAA battery
- one spoke magnet with thumb screw

The BadassBox 4 Fazua is fitted over the Fazua speed sensor next to the rear wheel. When the snap-lock clicks into position, the BadassBox is fitted securely to the sensor. For extra secure fitting, the BadassBox can also be fastened with a zip tie.

Once the BadassBox has been fitted onto the sensor, the spoke magnet must be offset to the casing edge in the direction of the snap-lock clasp. It's now ready for use.

Following removal of the BadassBox, the spoke magnet must be returned to its original position.
