The Tweedster is a shoulder bag that doubles as a cycle bag. It's the perfect size for your mobile phone and money or your bicycle repair kit. You can carry it comfortably over your shoulder or attach it to the handlebars or frame. The packs and bags in the Tweed Run series are inspired by the London event of the same name, where participants ride through the city's hippest districts on vintage bicycles, dressed in tweed outfits reminiscent of the 19th century. And anyone can take part.
