The most popular product from Sinewave Cycles is the Dynamo Light.
Its name is " Beacon "
It's very simple and rugged, yet beautiful. The toggle switch on the back gives off a truly USA-made feel that is irresistible. It's high-tech and high-performance, but it's well-made in a way that doesn't make it feel that way at all. This means it will match any bike seamlessly.
If you check Instagram, you'll see that it's often used on cool bicycles overseas.

The revolutionary thing about “Beacon” is that it can be charged via USB.
By switching the toggle switch to charge priority mode, you can charge your smartphone, Garmin or other cycle computers while riding.
It's reassuring to be able to enjoy your adventure without having to worry about the remaining battery life.

This may seem obvious, but the body is completely waterproof.
The internal electrical circuitry is coated with epoxy and gold plating. No problem even if there is a sudden downpour or it falls into a river.

Look at this beautiful anodized color...
Vivid colors and beautiful design never before seen in a dynamo.
There are a wide variety of colors available, and you can change the color of the front cap, rear cap, and body. It's nice to be able to customize the color to your liking.
To be honest, it's not cheap as a light, but if you look at riders overseas, it's clear that it's a valuable product.
We are currently adjusting the selling price, but would like to keep it as close to the local price as possible. I've been interested in this product for a long time, so I'd like to see it in person soon.
