With the badassBox 4 Bosch G4-SET you not only get all the necessary parts to tune your e-bike in one 'click', but you also save money.
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!
HOW TO INSTALL the badassBox 4:
For best results, during the installation of the badassBox keep the bike engine TURNED OFF at all times.
1) Remove the battery from the badassBox and make sure that it is fully charged. Wait before re-inserting the battery.
2) Slide the badassBox over the speed sensor and install the magnet on the wheel spoke. Align the magnet as shown below.
3) Make sure that the battery was removed from the badassBox for at least 30 seconds before re-inserting into the badassBox.
4) Turn on the system and make a few wheel turns. If the display shows a speed, the device is working.
On certain e-bikes models it may be advised to relocate the magnet on the rear spoke or to twist it at 90 degree (magnet facing up or down) to allow more tolerance between box and magnet.
The returned BadassBoxes are tested with a specific badass diagnostic tool for any errors/malfunctions. In the majority of the cases boxes are in good working conditions so please make sure that you have followed the instruction correctly before requesting a new unit.
BEFORE RETURNING THE BOX CHECK THAT THE BATTERY IS NOT THE CAUSE OF THE MALFUNCTION
