With the speed limit removed, 28-37mph (~45-60km\/h) can be expected, depending on the bicycle and gearing.\n\n\u003ch3\u003eHow does the Speedfun work?\u003c\/h3\u003e\nThe tuning kit manipulates the speed signal without altering the motor's power relative to pedaling speed. This guarantees a smooth motor control without speed limit interruptions. Depending on a tuning kit, some determine when assistance stops, while others remove the restriction entirely for continuous support. However, the achievable speed mostly depends on the eBike model. Achievable speed can be calculated using a simple formula: \u003cbr\u003e\u003cbr\u003e\n\nSpeed = Cadence [rpm] * Wheel circumference [mm] * Front Chainring Teeth \/ Rear Chainring Teeth * 60 [min\/h] \/ 1.000.000 [mm\/km]\n\u003cbr\u003e\u003cbr\u003e\nThe function of the Furious Ultra tuning device for Specialized 3.1 motor (Turbo Levo gen4) 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 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.\n\u003cbr\u003e\u003cbr\u003e\nWhen the tuning device is active, having no communication with the display, it will show the halved data on any display (or app) starting from a certain threshold.\n\u003cbr\u003e\u003cbr\u003e\nThis tuning kit can be installed on Specialized Turbo Levo (gen4) equipped with Specialized 3.1 motor and MasterMind T3.\n\u003cbr\u003e\u003cbr\u003e\nFurious Evo Ultra devices offer a choice of operating modes:\u003cbr\u003e\n\n– Always active, cannot be deactivated\u003cbr\u003e\n– Activated\/deactivated by pedaling with the wheel lifted\u003cbr\u003e\n– If tuning was active before turning off, it will also be active after turning it back on.\u003cbr\u003e\n– If tuning was active before turning off, it will be deactivated after turning it back on.\u003cbr\u003e\n– Tuning can be activated\/deactivated with an external button (not included in the kit).\u003cbr\u003e\nFor more information, see the instructions on the page.\u003cbr\u003e\nThe device is supplied plug and go ready to use and is installed in a very simple way thanks to the compatible connectors with which no physical modification of the ebike is necessary.\n\u003cbr\u003e\u003cbr\u003e\n\u003cb\u003eWARNING!\u003c\/b\u003e\u003cbr\u003e\nThis device is not compatible with Specialized Gen1, Gen2, or Gen3 e-bikes equipped with TCU01 (blue LED), TCU01 (Mastermind), or TCD.\nThis device is not compatible with Specialized ebikes equipped with motor-controlled electronic shifting.\n\n\u003ch3\u003eHow to use Speedfun Service Menu?\u003c\/h3\u003e\nACTIVATION\/DEACTIVATION - PEDAL SYSTEM\u003cbr\u003e\n- Place the chain in the highest gear (the smallest rear sprocket).\u003cbr\u003e\n- Place the left pedal at 11 o'clock.\u003cbr\u003e\n- Lift the rear wheel and apply a strong pedal stroke (just one, with your foot). Let the wheel spin above 30 km\/h for a few seconds.\u003cbr\u003e\u003cbr\u003e\nThe system recognizes acceleration and considers it as a command to activate or deactivate (cyclically) the speed release. When activated, the display shows the speed changing from real to halved. When deactivated, the display shows the speed changing from halved to real, and the bike returns as original.\n\n\u003ch3\u003eIs this Speedfun the right tuning kit for my bike?\u003c\/h3\u003e\nThis Speedfun tuning kit is made to work with \u003cb\u003eSpecialized 3.1 motor ONLY\u003c\/b\u003e with any combination with all available displays and the Speacialized application.\n\u003cbr\u003e\u003cbr\u003e\nSpecialized ebike with 3.1 motor where the Furious Ultra device was successfully installed\n(this list is illustrative and not exhaustive)\u003cbr\u003e\u003cbr\u003e\n– Specialized S-Works Turbo Levo 4 LTD\u003cbr\u003e\n– Specialized S-Works Turbo Levo 4\u003cbr\u003e\n– Specialized Turbo Levo 4 Pro\u003cbr\u003e\n– Specialized Turbo Levo 4 Expert\u003cbr\u003e\n– Specialized Turbo Levo 4 Comp\u003cbr\u003e\n– Specialized Turbo Levo 4 Comp Alloy\u003cbr\u003e\n– Specialized Turbo Levo 4 Alloy\n\n\u003ch3\u003eHow to install this Tuning kit?\u003c\/h3\u003e\nWhen connecting Tuning Kit to an e-bike you will find connectors colored to make installation very simple.
