SpeedFun Furious Ultra: tuning for Specialized Turbo Levo 4 with 3.1 motor
SpeedFun Furious Ultra is an e-bike tuning device for Specialized Turbo Levo 4 with the Specialized 3.1 motor, designed to remove the 25 km/h assistance limit.
The device electronically modifies the signal related to the rear wheel rotation speed, communicating a lower speed to the motor. This allows motor assistance to continue beyond 25 km/h. The actual maximum speed depends on motor power, riding conditions and the power generated by the rider (more information).
When Furious Ultra is active, as there is no direct communication with the display, speed and distance data shown on the display and in the app are altered above a certain threshold.
This tuning kit is compatible with Specialized Turbo Levo 4 e-bikes equipped with the Specialized 3.1 motor and MasterMind T3. Turbo Levo 4 models are also commonly referred to as Turbo Levo Gen 4 or Gen4.
With SpeedFun Furious Ultra, different operating modes can be selected:
- Always active and cannot be deactivated
- Activated/deactivated using the foot switch with the wheel raised
- If tuning is active when the e-bike is switched off, it remains active after restarting
- If tuning is active when the e-bike is switched off, it is deactivated after restarting
- Activated/deactivated using an external button (not included in the kit)
For further information about the available operating modes, please refer to the installation instructions.
The device is supplied plug and play, ready to use. Installation is straightforward thanks to the compatible connectors and requires no physical modifications to the e-bike.
