In this video project Engineer/Youtuber Tom Stanton is building an experimental bicycle that replaces the traditional gear system of the bicycle with a magnetic clutch.The magnetic clutch is made up of two discs.

One disk is made of copper and the other made of aluminum, with 200 neodymium magnets mounted on the aluminum disc.Tom Stanton wanted to see if it was possible to create a bike transmission that uses magnets to turn its wheel and create resistance.
The copper disc is stationary to the bicycles wheel and acts as the brake rotor and the other disk the aluminum one is connected to the pedals via a chain and rotates when the pedals are turned.
The magnets on the aluminum disc generate eddy currents in the copper disc, creating resistance that can be used to control the speed of the bike.Instead of the worm gear structure, it has the advantages of high drive, low noise, and less maintenance.This gearless magnet bike is just an interesting experiment in using magnetic technology in bicycles.
