Büchel offers a lot of light for a reasonable price, with no real weaknesses apart from the glare in the saddle. The automatic mode with automatic light dimming works perfectly and is a real highlight.

Sensible automatic. Good, but somewhat narrow illumination up to 18 metres. Suitable for most cyclists, less so for fast cyclists. The optional automatic system adjusts the brightness slowly and sensibly. Light duration is poor, but at least it charges quickly.
