✅ EPAspeed BOX |
|
Installation Time |
Tool-free installation; mounts on the chainstay in approx. 1–2 minutes. |
Same fast installation time (1–2 minutes), with a more secure and vibration-resistant fit. |
|
Maximum Supported Speed |
Assistance typically increases up to 35–37 km/h, depending on wheel size. |
Same assistance range of 49-50 km/h, but with higher measurement accuracy thanks to improved sensing. |
|
Speed Display Accuracy |
Output speed on the bike’s display becomes random and highly inaccurate, requiring an external GPS device for correct speed readings. |
Maintains correct display readings using a 1 : 2 speed-correction algorithm, providing accurate speed feedback without external devices. |
|
Battery Lifetime |
Approx. 5,000 km or ~6 months under regular use. |
Approx. 8,000 km or ~12 months, depending on conditions — engineered for extended service life. |
|
Build Quality |
Uses standard materials; the pin-lock mechanism is prone to wear and may break under repeated removal or vibration. |
Reinforced enclosure designed to lock directly into the speed sensor with enhanced durability and anti-vibration structure to prevent failures. |
|
Included Components |
Box, magnet, battery. Spacer not included, which may be required for some chainstay geometries. |
Box, magnet, battery. Includes multiple spacers, anti-vibration shims, and zip ties for universal and secure fitting. |

If the Shimano Sensor (first picture) is mounted easily accessible on your chainstay, you only need a badassBox 4 Shimano 2019.
badassBox 4 for SHIMANO X-SET
The badassBox 4 Shimano X-Set includes all the parts you need to mount the badassBox 4 on your e-bike with a Shimano mid-mounted motor and Shimano Sensor integrated in the fork-end.
- badassBox 4 Shimano 2019
- Universal Adapter
- Spoke magnet with thumb screw
INSTALLATION
To get to the sensor you have to dismount the rear wheel.
Find the position of the integrated sensor* in the fork-end of your e-bike.
*The sensor shape shown is an example.
Undo the screws of the bracket that holds the sensor* is fastened to the fork-end.
*The sensor shape shown is an example.
*The sensor shape shown is an example.
Now you can attach the Universal Adapter with mounted Shimano Sensor* on the chainstay with supplied cable ties.
*The sensor shape shown is an example.
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 THE BADASSBOX 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.).
