Badass Box 4 Shimano 2020 (for e-bikes with integrated Shimano sensor SM-DUE11)
This is a simple but highly effective tuning tool specifically for Shimano e-bikes with a Shimano sensor integrated in the dropout SM-DUE11 (see figure below). The Badass Box 4 completely removes the 25 km/h speed limit, allowing you to finally utilize the full potential of powerful Shimano drives. This tuning tool doesn't offer any additional features. With the Badss Box 4, the annoying 25 km/h speed limit on your Shimano e-bike is finally a thing of the past – and you can ride much faster with full motor support.
The Badass Box 4 must be attached to the chainstay of the Shimano e-bike, together with the screwed-on speed sensor.
Important: Please note that for the installation of the Badass Box 4 Shimano 2020 a small modification to your e-bike is necessary. Please read be sure Please read the installation instructions below before you decide to order this tuning tool.
Before ordering, you should also check whether the cable of your sensor can be pulled out far enough from the dropout to allow the sensor to be attached to the chainstay in front of the brake disc. Only then can the sensor be installed together with the Badass Box 4 use.
Legal status can be restored
After connecting the wiring, the tuning can be switched on and off by plugging and unplugging the box. You can restore the legal (untuned) state of your e-bike by Badass Box and mount the Shimano sensor on the chainstay, or the original installation situation in the dropout and align the spoke magnet to it again.
More robust than ever before
The electrics of the Badass Box 4 is glued and sealed into the housing with a special casting compound from the automotive industry, making the box more robust and less sensitive to moisture than any other Badass Box Variants before.
Each Badass Box 4 is thoroughly tested for correct function before and after casting.
How does it work Badass Box 4 for Shimano 2020?
After installation, the Badass Box 4 sends a modified signal to the motor, thereby overriding or canceling the 25 km/h speed limit. This occurs contactlessly, meaning there is no electrical connection to the motor and no interference with the motor electronics. This eliminates the risk of damage.
Please keep in mind: Due to this special operating principle, your e-bike's display will no longer show the correct current speed when tuning is active (= box plugged in), and this also applies to any values derived from it. We therefore recommend using GPS-enabled additional devices such as your smartphone to record the actual data. You can do this using special "brackets“ directly to your handlebars so that you always have an optimal view of all driving data.
The Badass Box 4 is powered by an included AAA battery. Thanks to the specially developed and patented FEET (Field Enhancement & Elimination Technology), you can go a long way on a single battery. If the battery runs out, it can be easily replaced at any time without the need for tools. Suitable replacement batteries are available almost everywhere. We recommend replacing the battery once a year at the start of the season.
