Description
Unlock the speed limit of your electric bike with a Specialized badassBox tuning box. The badassBox is the easier ebike tuning to install and remove. No wiring or engine cover removal required – just slide the badassBox over the speed sensor and you are ready to go! Unleash the full speed of your ebike engine and ride it as fast as you can!
NOTE: The BadassBox enables motor assistance up to approximately 35–37 km/h but does not maintain accurate speed data on the onboard display. As a result, riders must rely on external GPS devices (e.g., bike computers or smartphones) to obtain correct speed readings.
In contrast, the EPAspeed BOX supports assisted speeds of up to 50 km/h while preserving full accuracy of the factory speedometer — offering the most advanced contactless tuning solution currently available.

HOW TO INSTALL THE BADASSBOX:
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.
NOTE:
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.
RETURNS:
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.
