NOTE: Conventional tuning modules offer only limited functionality compared to today’s e-bike standards. They often rely on complex and unintuitive display button sequences for activating, deactivating, or adjusting speed limits. This makes operation cumbersome, especially during a ride. In some cases, users must stop the bicycle and manually rotate the rear wheel multiple times to initiate or confirm the selected setting — a process that is inefficient and inconvenient for real-world riding conditions.

SpeedBox 3.1 B.Tuning disables the speed limiter on your Specialized e-bike (including SL motors) and TCU/MasterMind TCU unit, allowing you to ride at unlimited speed. After installation, real data such as maximum and average speed, daily mileage, and range are displayed on your e-bike's screen.
With the SpeedBox App, you can monitor and store all trip parameters on your phone – anytime, anywhere.
How does SpeedBox 3.1 B.Tuning for Specialized work?
Install the SpeedBox inside the e-bike frame under the TCU/MasterMind TCU unit. Activate tuning by turning your e-bike off and on twice. Tuning remains active with a default max assistance speed of 50 km/h.
You can adjust the speed limit in the App or manually by cycling through modes (TURBO → TRAIL → ECO → OFF → ECO → TRAIL → TURBO). The default limit is 25 km/h. Each press of the WALK button raises the limit by 5 km/h. For example, 2.5 km/h on the display = 25 km/h limit, 5.0 km/h = 50 km/h.
The set limit is saved after 5 seconds of inactivity and must be confirmed by turning the bike off and on twice. You can check the current limit via the App or the + - + - button combo.
SpeedBox App for SpeedBox 3.1 B.Tuning
The SpeedBox App connects your e-bike with your mobile via Bluetooth. It provides real-time data, trip logs, and advanced features:
• Tuning control
• Speed limit adjustment

Try the App before purchase with the demo mode. Your phone must support Bluetooth 4.0 or higher.
