Those like me who lives at the Fläming-Skate and is often overtaken on liners of (racing) cyclists without them making their presence felt, who knows the importance of ensuring appropriate and timely signaling is. This bell I have now mounted on my bike and the term "bicycle safety" applies here full point. A bright louder Zweiklang is hard to miss. Small size and easy installation are other advantages. If you're looking here and wants to put a bell is well advised with this product.
