Review on 🚴 LESOVI Electric Bike Horn 120 dB - Cycling Scooter Horn with 4 Sound Modes, Rechargeable Battery & Waterproof Design - Ideal Bicycle Accessory for Kids, Boys, Adults, Mountain Bikes - Bells & Whistles by Mido Taylor

But I like the design and the charging functions. I just read that blacks have adjustable volume, so now I know. This is unregulated and very loud. To be honest I would be uncomfortable using it when people just walk the dogs you have. I found a simple solution and void any warranty. I filled the round notch on the front panel with silicone and it's now around 90dB. Fits me perfectly and I don't have to send it back. Another solution is to split and cover the tennis ball. Silicone is lighter but irreversible. hp A regular o-ring can be used to reduce or reduce the size of the band provided - it's tiny and only suitable for handlebars.
