SpeedBox 3.1 B.Tuning Brose ir Specialized varikliams

New generation tuning product with Bluetooth and mobile app for your e-bike. Our most powerful and versatile product.

This new device brings a unique connection of e-bike and mobile phone. The SpeedBox 3.1 B.Tuning is a top-notch product perfectly optimized for the most powerful ride and experience. It suppresses the speed limiter so you can enjoy your ride at unlimited speed. Thanks to SpeedBox App mobile application you can monitor and store all the parameters of your trip on the display of your phone in any place, anytime.

The tuning kit manipulates the speed signal without altering the motor's power relative to pedaling speed. This guarantees a smooth motor control without speed limit interruptions. Depending on a tuning kit, some determine when assistance stops, while others remove the restriction entirely for continuous support. However, the achievable speed mostly depends on the eBike model. Achievable speed can be calculated using a simple formula:

Speed = Cadence [rpm] * Wheel circumference [mm] * Front Chainring Teeth / Rear Chainring Teeth * 60 [min/h] / 1.000.000 [mm/km]

Our newest product features an easy and user-friendly control unit. The tuning kit can be activated directly from the mobile application or on your bike’s display. By activating the WALK assist function shortly a value of 9.9 km/h (6.2 mph) is displayed and from now on you will be able to ride at a speed of 40 km/h, 50 km/h and even more than 60 km/h.

To deactivate the tuning kit, activate the WALK assist function again. The value of 2.5 km/h (1.6 mph) will appear on your display and the speed limit will reset to 25 km/h. Your e-bike will then work the same as before installation of the product.

SpeedBox was also designed for e-bikes that do not have a classic control unit with WALK assist function. In this case you can just use the combination of + - + - buttons and SpeedBox will be activated. You can easily deactivate SpeedBox in the same way.

You can set the maximum speed of an electric assistance in SpeedBox App or by changing modes: TURBO - TRAIL- ECO - OFF - ECO - TRAIL - TURBO. An actual speed limit will be displayed after that. The maximum speed of an electric assistance can be switched by activating WALK assist function shortly or by turning the rear wheel 360°. The value of 1,5 km/h on the display corresponds with the limit of 15 km/h, 2 km/h corresponds with the limit of 20 km/h, 2,5 corresponds with 25 km/h, 3,0 corresponds with 30 km/h, 9,9 corresponds with 99 km/h etc. The last displayed limit will be saved after 5 seconds of inactivity.

Activation and deactivation of SpeedBox tuning for e-bikes with SRAM Powertrain unit

To activate or deactivate the tuning, briefly activate the WALK function or switch between two assistance modes (+ - + -).
Activation of tuning (unlimited speed) → the display will show a battery value of 99%, which corresponds to a maximum speed of 99 km/h.
Deactivation of tuning (limited speed) → the display will show a battery value of 25%, which corresponds to a speed limit of 25 km/h.
Setting the maximum assistance speed:
To set your custom maximum assist speed, first open the SRAM AXS app and go to the Ride Modes section. Here, it is possible to adjust the parameters of individual modes, such as Max Power, which you first decrease three times and then increase three times. The control unit briefly displays the current speed limit as the battery level in %. Then, using the WALK function, gradually set the maximum speed – each press increases the battery value by 5%, which corresponds to raising the speed limit by 5 km/h. For example, showing 55% battery means a 55 km/h limit, 60% means 60 km/h, and so on. The last displayed limit is saved after five seconds of inactivity.
