New York bike maker Priority Bicycles has launched what it's calling its "most compact and versatile bicycle yet." The Folder collapses down to 30 x 24 inches for between-ride transport or storage, features a Gates Carbon Drive and a geared hub, and is priced at under $800.
I’ve never tried one. I have chains on my hybrid MTB and my eFatbike, they’ve been pretty reliable for me though.
