For everyday use with 5V-21V e-bikes with a maximum speed of 25km/h (32km/h in Canada), the Supernova V521S is well suited for any commuter or adventure seeker. The light weighs in at a slick 75g, making it easily one of the lightest e-bike headlights available. The Terraflux 3 lens and new high-performance LED produce 15% more light than its predecessor - 235 lumens, to be exact.

    Supernova Company History: The year 1995 saw a tomato paste can, a halogen bulb, and motorcycle battery turn into a headlamp - and so came the first of countless innovations from Supernova. From then on, Marcus Wallmeyer took his original idea and designed a company that could allow riders from many disciplines, primarily mountain bikers, to ride into the night on unlit and relatively uncharted paths. The lights to follow brought about some of the brightest and most powerful lights the industry had ever seen. As the concepts grew bigger (dynamos, pedelecs, and battery) the designs got smaller and even more powerful. In 2004, the E3 dynamo headlight and tailight were produced to huge acclaim and numerous awards. Supernova continues to be the go-to for the best design, meticulous engineering and near-perfect functionality
