SpeedBox 3.1 B.TUNING for YAMAHA PW-X3

Description

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.

In contrast, the EPAspeed B.Tuning series represents the next generation of e-bike tuning — fully app-controlled, firmware-resistant, and designed for effortless operation. With Bluetooth connectivity, intuitive controls, and invisible tuning functionality, EPAspeed delivers precision, reliability, and freedom unmatched by conventional solutions.

• Adjustable Speed Limits – Set your preferred maximum assistance speed
• Invisible Tuning Mode – Undetectable operation for smooth and safe performance
• Trip Recording – Automatically save and review detailed ride statistics
