【Loud&Clear】 Our new aluminium alloy bicycle bell can sound bright and loud. A highly elastic spring inside the bell provides a stable and long-lasting sound of 90-100dB, and the spherical spring paddle ensures comfort in the hand during use and has a good striking feel. Even on noisy streets, passers-by can hear the pleasant sound of your bell to keep you safe on the road. 【Innovative&Hidden】 The small, lightweight bell has an innovative design. The small bell does not take up much space and can be hidden on the handlebars. Therefore, the bicycle bell does not interfere with the use of the mobile phone holder, handbrake or gear lever. Simplified shape also fits well on mountain and road bikes. 【High quality material】 The bell is made of aluminium alloy and stainless steel, which are rust-resistant and allow riding in the rain. The PA base and anti-slip discs are both durable, which helps in gripping the bell securely on the handlebar. 【Easy to Install】 Our bicycle bell is very easy to install. The package contains a bicycle bell and an Allen key. You must first unscrew the screw with the Allen key, place the bell in the right place on the handlebars and set it to the right angle. Finally, use the Allen key to tighten the screws. Material: Aluminium alloy+stainless steel+PA Size: 4.5*4.5*1.9cm Volume: 100dB Applicable size: 22.2mm Colour: Black, Red, Titanium
