SPEEDFUN E-Bike Tuning Solutions

SPEEDFUN, manufactured by PHASE B snc in Italy, develops high-performance tuning kits and speed unlocking devices for electric bicycles. Their innovative plug-and-play modules, such as the Furious EVO and Ribelle systems, are engineered to override the standard 25 km/h factory speed limits on major pedal-assist e-bike motors, including those made by Yamaha, Bosch, Fazua, TQ, and Brose.

With a focus on seamless integration, SPEEDFUN devices allow riders to experience the full potential of their e-bikes without permanently altering the system. While specifically intended for off-road or private terrain use, these tuning systems provide reliable features such as real-time speed display adjustments, customizable activation thresholds via handlebar controls, and secure, hidden installations inside the motor housing.

• Does installing a SPEEDFUN tuning kit void my e-bike's warranty?

  Yes, modifying your e-bike with a SPEEDFUN unlocking device typically invalidates the manufacturer's warranty. It is also intended only for use on private property.

• Can the SPEEDFUN speed release function be deactivated?

  Yes, depending on the model (like the Furious EVO), the speed release can be activated and deactivated at will, often by pressing a key sequence on the handlebar control or by interrupting a specific wire loop.

• Are SPEEDFUN tuning devices completely waterproof?

  No, SPEEDFUN tuning modules are generally not fully waterproof. You should position the module in a protected area inside the engine casing and avoid direct water exposure.

• Will my e-bike display show the correct speed with a SPEEDFUN device active?

  On some versions like the Furious EVO, speeds above certain thresholds will display as halved or divided by three. However, more advanced modules like the Ribelle variant process the data to show the real speed and accurate distances on your display.
