SpeedBox B.Tuning 3.0 For all 2014-2023 Bosch Motors

The SpeedBox 3.0 B.Tuning chip 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]

The tuning kit can be activated directly from the mobile application or on yours bike display. After pressing the 'WALK' or '+ - + - ' or 'WALK' and '+' buttons, a value of 6.2 mph or 9.9 kph is displayed and from now on you will be able to ride at a speed of 25mph (40 kph), 31mph (50 kph) and even more than 37mph (60 kph). As much as you can pedal!

At the first start, SpeedBox App will ask you to create a new PIN code to provide maximum security for your e-bike. This code will serve for everyday access to your App.

After creating your PIN code, SpeedBox App will ask you to set up your Service password. This will serve you in case you need to change the PIN code.

You can set the maximum speed pf an electric assistance by changing modes: Turbo - EMTB- Tour - Eco - Tour - EMTB - Turbo. An actual speed limit will be displayed after that. The maximum speed of an electric assistance can be switched by pressing 'WALK' button shortly or by turning the rear wheel 360° .

The value of 0.93 mph (1.5 kph) on the display corresponds with the limit of 9.3 mph (15 kph),
1.2 mph (2 kph) corresponds with the limit of 12.4 mph (20 kph),
1.5 mph (2.5 kph) corresponds with 15.5 mph (25 kph),
1.8 mph (3.0 kph) corresponds with 18.6 mph (30 kph),
6.1 mph (9.9 kph) corresponds with 61.5 mph (99 kph) etc.
The last displayed limit will be saved after 5 seconds of inactivity.

When using SpeedBox 3.0 B. Tunng with Bosch motors of the 4th generation (produced in 2020 or later) it is necessary to leave the bike on after finishing the ride until a value of 0.0 mph or 0.0 kph is displayed. During this process the remaining time will be displayed in minutes. Then it is safe to turn off your bike and you can start looking forward to your next trip.
