Supernova Horn 2 Black. The ultimate horn for e-bikes with the typical low-frequency horn tone. Our e-bike horn not only relies at maximum volume but also on a characteristic horn tone that is perceived and perceived in every traffic situation. In contrast piezo horns which are often used for e-bike horns create a high shrill tone which is less effective in many traffic situations and can be more easily ignored. Our horn is made for everyday use. It is weatherproof shockproof and durable – perfect for all conditions. The Supernova Horn 2 can be operated on all common 12 V e-bike drives.
