This is a new mechanism for your bicycles, I am sure you will love it. No headache of chain drop during a ride.
The Bicycle is much softer and smooth in ride on this gear mechanism but working gears produces some noice which is definitely bearable and sometimes cool to hear.
Good luck with this new information you can make your own chainless bicycle now. People in surroundings love this invention.
