The essential core of this controller uses a rotary encoder which is then connected to an Arduino Uno to read the speed of the revolutions and converting that into the gain of axis direction on an Xbox controller. Thanks to SilicDev with their coding skills to make this possible

For the bicycle to be attached to the rotary encoder, NanakiEmi, Mintopia and Sparky373 did rapid prototyping and engineering to be able to 3D print off custom parts to fit the encoder into and gears which fit the chain perfectly and safely for long usages
