About

Belt Drive Notes is a small, independent site about one thing: Belt drives on e-bikes: how a carbon belt drive replaces the chain, what it needs in frame design, tension and care, as set out in belt makers' technical pages and bike makers' manuals.

The pages draw on published material such as manufacturers' manuals and specifications, government and university pages, and encyclopedias. Each page lists the sources behind it at the bottom, along with the date it was last checked.

There are no ads here, and nothing is for sale.

What you read here is general information. Your own equipment's manual comes first, and where safety or the law calls for a qualified tradesperson, use one.
