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.
Key Features
• Tuning Control – Instantly activate or deactivate tuning
• 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

After installation, the tuning is activated by pressing the WALK button, a value of 9,9 km/h (6,2 mph) appears on the display for approx. 3 seconds. This signal confirms that the tuning is activated and that the engine is now fully derestricted for speed up to +99km/h (most likely you will run out of gears before reaching that speed).

HOW TO SET UP THE MAXIMUM SPEED
To set the maximum speed, the mode must be changed: Turbo – Sport – Tour – Eco – Tour – Sport – Turbo. The current speed limit is then displayed. To change the current maximum speed, briefly press the WALK button or turn the rear wheel 360°. A displayed speed of 1.5 km/h corresponds to a maximum speed of 15 km/h, a displayed speed of 2.0 km/h corresponds to a maximum speed of 20 km/h, 3.0 km/h in the display corresponds to a maximum speed of 30 km/h etc. If 9.9 km/h is finally displayed, this corresponds to a maximum speed of 99 km/h. After five seconds of inactivity, the last saved limit is saved.
For the 4th generation (MY2020) Bosch engines, you must leave the ebike switched ON after you have finished your ride and until the display shows a constant speed of 0.0 km/h. Within this time the display will show the remaining time in minutes. Then the ebike can be safely parked.
