The Blast Airhorn is capable of putting out up to 115 decibels of trumpeting glory. That, combined with its ability to fire off 30-50 blasts before needing to be refilled by way of any regular bicycle pump, makes this biking accessory very effective. So, if you carry a mini bike pump, you can blast away on your horn to your hearts content knowing you can quickly refill it at anytime. To top it off, the whole thing weighs in at less than 100 grams, so there’s no worry about adding too much weight to your bike.

I have used the Blast Airhorn on bike rides in the mountains of Northern Idaho in the winter, on the San Juan Islands off the coast of Washington state, all over the San Francisco Bay Area, around remote areas of Northern California and even in Death Valley. Not once did the Biologic Blast Airhorn fail me.

Installation of the horn is straightforward and very similar to most other bike accessories that strap to your handle bar. It even has a quick release capability so you can remove the horn when you are not on a ride, thus it won’t get stolen. This also comes in handy if you want to use it off the bike, such as when kayaking to make your presence known to other boaters, or to scare off wildlife when hiking in bear and mountain lion territory, or even at night on a city walk to ward off a would be attacker!
