Tax includedShipping calculated at checkout

Unlock the speed limit of your electric bike with a Shimano 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 like a derestricted e-bike should be!

Attention, you need this set only if the Shimano Sensor SM-DUE10 (first picture) is integrated in the fork-end of your bike.
If the integrated sensor looks like the one in the second picture, then it is the SM-DUE11 from Shimano. Then you need the badassBox 4 Shimano 2020.
If the Shimano Sensor (first picture) is mounted easily accessible on your chainstay, you only need a badassBox 4 Shimano 2019.

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.

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.).
