Description
Highly waterproof, dynamo-compatible front light that can be used safely in bad weather and on long outdoor rides
SINEWAVE CYCLES, based in Cambridge, Massachusetts, USA, is a specialist brand of dynamo power generation equipment for bicycles.
Sinewave Beacon2 has evolved significantly from the original model, ensuring stable brightness with almost no flickering even at low speeds.
Furthermore, it is equipped with two modes, high brightness (approx. 750 lumens) and low brightness (125 lumens), that can be used according to the situation, making it ideal for use as a daylight or as a reminder to oncoming traffic.
It also has a stand light function that is charged while the vehicle is in motion, ensuring at least 5 minutes of "visible light" even when the vehicle is stationary. When using an external battery, the light can be turned on indefinitely, making it useful as a work light at campsites.
Furthermore, the main body of the light has a built-in USB charging function, allowing direct charging of smartphones, GPS, and mobile batteries while driving. When the light is off or in low-luminance mode, it is controlled to provide a stable USB power supply.
The beam pattern is round, making it ideal for on-road as well as off-road, MTB, and bikepacking.
It is also waterproof and durable enough to be used in bad weather and for long outdoor rides.
