What is Bafang M400 and M420 SpeedFun Furious Evo ebike tuning?<\/h2>\n

The function of the Furious Evo tuning device for Bafang M400 and M420\u00a0<\/strong>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 (info<\/a>).<\/p>\n

When the tuning device is active, having no communication with the display, it will show the halved data on the display starting from a certain threshold.<\/p>\n

SpeedFun Furious Evo can be activated and deactivated at will and maintains the setting even after the ebike is turned off. It can be installed on ebike with Bafang M400 and M430 motors regardless of the type of display or side control of the ebike.<\/p>\n

The Furiosu Evo tuning device for Bafang M400 and M420 can be activated\/deactivated by simply pressing the ebike’s light button. If the ebike already has the lights connected to the light output, or if it is not possible to use it, it will still be possible to activate\/deactivate the tuning with a very practical system (for more information see the instructions here). The device is supplied plug and go ready to use and is installed in a very simple way thanks to the original connectors with which no physical modification of the ebike is necessary.<\/p>\n

 <\/p>\n

WARNING 1<\/strong>
Since 2020, speed sensors with 4-pin connectors are being produced instead of 3 (click here<\/a>) as previously.
\nBefore buying, it is important to check the version of the speed sensor connector of your bike to avoid incompatibility problems of the Furious Evo device with your engine.
\nBy clicking here<\/a> you can easily recognize whether a 4-pin or 3-pin connector has been mounted on your ebike.<\/p>\n

WARNING 2<\/strong>
If the ebike is equipped with lights, it is recommended to purchase the Y-splitter cable (model CY-01)<\/a> together with the device.\u201d<\/p>\n
