I've tried the AirZound at a bike shop, great for auto traffic, not so good for pedestrian traffic My only concern with the system is that many ebikes don't have even one water bottle mounting location/bosses. If you do will you want to use your one for a horn?I am a bit too late, but with this one's 115 dB you could have blasted anyone out of your way.
Topeak introduced a light/bell/horn and I think it beats the Orp! The Soundlite, I wish they had it out before I had purchased the Orp. Nicest part is the wireless remote and it costs about the same as the Orp.- car horn
- normal bike bell but loud
