Fazua motors use very specific speed sensors, whose shape and positioning decide on the badassBox to be used.
Where is your sensor?
The speed sensor and its positioning are decisive for which badass box you need.
We distinguish between the classic mounting on the chain stay and the integrated mounting in the area of the dropout.
Sensor on the chain stay
A good indication that your sensor is on the chain stay is the presence of a spoke magnet. In addition, the sensor is usually direct and easily visible.
Fazua Sensor
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.
Attention, the badassBox 4 Fazua is only compatible with the sensor shown in the first picture. The sensor is easily accessible on your chainstay
(see red marked area in the 2nd picture).
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.
Badass eBikes proudly presents: the new improved badassBox 4 Fazua
The badassBox 4 is the result of more than a year's development. We have completely re-designed the casing, made
it more streamline and replaced the o-ring of the previous version with our patented snap-lock fastening. Making it
more streamline makes it even easier to fit. The new snap-lock fastening means you can attach and remove your
badassBox with just one hand in seconds. At customer's request, we have additionally added an optional securing
feature on the snap lock using a cable tie.
The CR2 battery has been replaced with a AAA battery, so you can pick up replacement batteries much cheaper on
just about any street corner. Tool-free battery change can be carried out quickly and easily while you're on the
road. We recommend replacing the battery at least once a year at the start of the season. Due to our specially
patented field enhancement technology FEET (Field Enhancement & Elimination Technology) you get very far with one
battery. To protect against moisture and mechanical stress, the electronics are glued into the casing and completely
sealed with a special casting compound.
The badassBox is developed and manufactured exclusively by us in-house. Before and after casting we check each
badassBox individually. Customer satisfaction and quality are our top priorities. If you have any questions, don't
hesitate to ask – we'll get back to you with an answer straightaway, mostly on the same working day. Due to the high
quality and our focus on customer satisfaction, we additionally offer a 1 month money-back guarantee.
In a nutshell
The badassBox is attached to the speed sensor of the e-bike and overrides the 25 km/h speed limit. Remove it and
your e-bike is restored to its original state.
Contactless e-bike tuning
Streamlined, registered design for casing
Patented snap-lock fastening
Securing feature on the housing
Patented field enhancement technology
Auto industry potting compound
Doubled quality control
Made in Germany

Installation
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.
When the badassBox is first fitted, the spoke magnet that comes with it must be mounted in place of the original
magnet. Without the badassBox, our spoke magnet functions identically to the original magnet, but when the badassBox
is fitted, the spoke magnet is necessary for our patented field enhancement technology to work properly. 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.

How it works
The contactless and wireless badassBox transmits a modified 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 in seconds – and just as quickly removed, restoring
your e-bike to its former road-legal condition.
For all these advantages, a wrong speed, and values derived from it, are displayed. We recommend the use of
GPS-related accessories for a more precise data acquisition of driving data (smartphone, bike computer, etc.).
