badassBox for Trek e-bikes

Trek uses different 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.

Bosch Sensor

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

badassBox 4 Bosch
Attention, the badassBox 4 Bosch is only compatible with the sensor shown in this picture. Badass eBikes proudly presents: the new improved badassBox 4 Bosch 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. 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 One month money-back guarantee Installation The badassBox 4 Bosch is fitted over the Bosch 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. .responsive-video { position: relative; padding-bottom: 56.25%; padding-top: 30px; height: 0; overflow: hidden; } .responsive-video iframe { position: absolute; top: 0; left: 0; width: 100%; height: 100%; } 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.).

Integrated sensor

If the sensor is integrated, then you do not have a spoke magnet, but instead a magnet on the brake disc.
To get a good view of the sensor, it is recommended to remove the rear wheel.

Bosch G4 Sensor

If this sensor of your Trek ebike with Bosch, Fazua or TQ motor - as shown in the picture below - is integrated in your bike, then the badassBox4 Bosch G4 set is exactly what you need. This sensor is used by Trek.

badassBox 4 Bosch G4-Set
Attention, only the G4 Speed Sensor (first picture) is compatible with this set If the integrated (in dropout) sensor has the shape of the sensor in the second picture (Bosch Sensor), then you need the badassBox 4 Bosch X-Set If the Bosch Sensor (second picture) is mounted easily accessible on your chainstay, you only need a badassBox 4 Bosch. Badass eBikes proudly presents: Das neue badassBox 4 Bosch G4-Set The badassBox 4 Bosch G4-Set includes all the parts you need to mount the badassBox 4 on your Trek e-bike with Bosch, Fazua or TQ mid-mounted motor and integrated G4 speed sensor: badassBox 4 Bosch G4 Adapter Spoke Magnet with Thumb Screw With the badassBox 4 Bosch X-Set you not only get all the necessary parts to tune your e-bike in one 'click', but you also save money. Installation The integrated Bosch Sensor is located in the area of the dropout. To get to the sensor you have to dismount the rear wheel. With the included button head screw you can screw (for this you need a 2.5 mm Allen key) the G4 speed sensor to the G4 adapter (1). (2) A suitably cut pad made of self-adhesive elastic foam is included as an option. This pad can be glued to the G4 adapter to attach it to the chain stay without the risk of scratches. With the enclosed cable ties (3), you can mount the G4 adapter including screwed G4 speed sensor at a suitable location on the chain stay (4), where it is possible to slide the badassBox over the adapter. Slide the badassBox onto the adapter until it clicks into place. Reinstall the rear wheel. Mount the spoke magnet and align it with the edge of the badassBox housing. That's it. Have fun with your faster e-bike!
