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

SpeedFun TQ-HPR40, HPR50, HPR60
SpeedFun Furious is an electronic and smart speed release device that needs no external power.
It is designed for use with TQ-HPR50 engines to circumvent the 25 KmH speed limit and allow for an increase in its active assistance up to speeds that can exceed 50 KmH by exploiting the motor’s power to the full.
SpeedFun Furious Evo easy+ is a tuning for ebikes equipped with a TQ HPR50 motor that allows you to remove the 25 km/h speed block.
This release device is specially designed for TQ HPR50 motors mostly used by Cube, Focus, Riese & Muller, Haibike, Ghost, Bulls and many others, regardless of the display or handlebar control.
All SpeedFun Furious Evo speed release devices can be activated and deactivated at any time and without the need for connections to the light output.
HOW DOES THE SPEEDFUN FURIOUS EVO TUNING FOR TQ-HPR50 WORKS.
The function of the Furious Evo tuning device for TQ HPR50 is to electronically manipulate the rotation speed of the rear wheel and to communicate to the motor a speed always lower than 25 KmH in order to obtain a real speed with a very high active motor. The maximum speed limit will therefore be dictated by the power of the engine added to the power expressed by one’s legs.
This speed release device is compatible with TQ HPR50 motor regardless of the display/handlebar control installed on the ebike. When tuning is active, the display (or app) will show the altered speed and km.
SpeedFun Furious Evo is supplied ready to use, plug and go, can be activated and deactivated as desired and maintains the setting even after the ebike is turned off. It can be easily installed thanks to the original and/or compatible connectors.
THE MAIN FEATURES
– Totally INVISIBLE
– Equipped with original and/or compatible connectors (does not require any physical modification to the ebike wiring)– It can be dismantled and reassembled at any time

– Installable in a few minutes, ready to use, plug and go!
