VelogicalThe VELOGICAL RIM DYNAMO is an extremely lightweight high end LED lighting power system for bicycles in a miniature form-factor. Its ‘hard skills’ are extremely smooth running (low drag) even at high riding speeds, minimal weight and high efficiency for use with modern LED bicycle lights. This compact dynamo genuinely weighs less than a mere 75g! And it operates with minimal resistance, below the perception threshold. Thanks to highest electrical efficiency it supports passive safety in traffic while working as a daylight running light, too. This patented bicycle dynamo for LED lighting has been developed especially for the requirements of sports-oriented cyclists and year-round cyclists.More info & order
