Very cool and sleek looking rear light. Sure to make all your cycling friends curious and jealous, it can be mounted under the saddle or on the seat post. An essential item once the light fades. I have a similar one but not the same brand, mounted on the seat post. It really helps you stand out in low light so cars can see you. Better safe than sorry.
