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
• Comprehensive Ride Data – Monitor distance, duration, average & max speed, and elevation

Even with the tuning active all data on the display remain accurate.
VOLSPEED QUALITY
The tuning hardware is completely encapsulated and protected by a rigid casing which guarantee for toughness, impermeability, and thus hardware longevity. The VOLspeed is manufactured in Germany.
FUNCTIONS:
• Individual activation code to prevent unauthorised riders to activate the tuning.
• Completely unlock the engine for speed up to 45 km/h.
• Set your own speed limit to adjust or reduce battery consumption.
• All settings can be easily made using the display control buttons.
• The tuning is always switched off after switching on the bike.
• Correct total mileage of the bike even after removing the tuning module, as the kilometres are tracked in the engine control by the tuning module.
• Range calculation remain accurate even with the tuning active.
• Set a ‘softer control behaviour’ (dynamic mode) which reduces the annoying engine abrupt cut-off. This allows for a more pleasant driving experience and a constant pedal stroke.
• Battery percentage remain accurate even with the tuning activated. In active mode the battery range is calculated as: Interval: 4 second range, 1 second battery level.
• Workshop mode: Deactivate the module completely, e.g. if a workshop visit is due.
• The electronics are completely encapsulated in the housing, making them absolutely waterproof.
• Does not require any diagnostic tool for installation.
EASY TO INSTALL
The VOLspeed tuning chip comes with original plugs and colour-coded wires for an easy and perfect fit. Installation manuals and videos provide step by step detailed instructions and are easy to follow and understand. The VOLspeed does not require any diagnostic tool for installation.
The tuning module is plugged into the connections of the drive unit. These are located under the left engine cover. Depending on the type of bicycle, you will need different tools to remove this cover. Most of the time you will need an ISIS crank puller and a Torx TX20 wrench. You can purchase a crank puller from us.
