You could easily install the light on pretty much any part of your bike.
They are very tiny little lights, but the battery lasts for maximum of 20 hours, and can be recharged with an USB cable.
The name "Koma"(Spinning Top) comes from a classic Japanese toy which looks very simular to the product.

Loved the aesthetics of this when I first saw it and it’s pretty bright for its small footprint. Good value too considering some other lights of brand are pretty much at the same level or more even. Bikeary was the only one who had it in the Philippines!
