Frequently Asked Questions
The BadassBox is attached to the speed sensor of the e-bike and overrides the 16mph (25 km/h) speed limit - you can expect to reach speeds of up to 31mph (50km/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 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.
This tuning kit is made to fit bikes with either the Bosch Slim speed sensor on the chain stay, or with the alternative Bosch Slim speed sensor integrated into the bike, with the magnet in the brake disc.
Your sensor should look like this if it's on the chain stay:
