SineWave Cycles designs innovative cycling accessories that make it easier for riders to charge their devices on the fly. From their home in Cambridge, MA, SineWave specializes in USB chargers specifically designed to integrate with dynamo hubs (hubs with a small electric generator within the hub that provide power to lights and other accessories).

As with any dynamo-related product, SineWave chargers place a premium on clean integration, and blend seamlessly and discreetly with your setup. These chargers will keep your phone, GPS, or lights running strong no matter how long the ride, making them the perfect solution for adventure-minded riders who tend to stray far from home.
