Cycle Delta Airzound Bike Horn , colors may vary

Absolutely great pump it up to about 85 psi easy to install if you have the right tools fits perfectly Very very loud my decibel reader red up to 130db louder than car horn if you pump it up to 85 psi it last about 12s straight probably has about 35 honks in it

Recently bought this product quite surprised for a great small item. The sound from it is amazing can be very effective for everyone to hear highly recommended light portable and easy to use.

Bought this to replace my old AirZound, which has given good service over several years but had started to get a bit leaky. The new one has a metal canister, rather than the plastic 'pop-bottle' on the old one. This can take more pressure (100psi / 7 bar) than the old one (80psi). Consequently, the horn is a bit louder when freshly pumped. The downside is that it's more difficult (in fact, impossible) to get an idea of whether you should give it a top-up before setting off on a ride. With the old plastic bottle, a quick squeeze would tell you if the pressure was getting a bit low. With the metal container, you simply can't do that. I wouldn't be without my AirZound - seriously loud and has averted several potentially nasty situations where motorists and pedestrians have not been paying sufficient attention. An essential, and inexpensive, aid to safety, and a potential life-saver.

Only got this in Sept 2025. I never take it off the bike so there should be no damage. It is releasing air at the top of the bottle so will not hold air. Css ad n only imagine if you where removing this every time to put air in it would be broken then sooner. Can’t see how to contact the company. Don’t waste your money buy a bell. 🤷‍♀️

I bought this after trying numerous bike horns- Including electric ones, and I have to say this is amazing. I have used this numerous times to stop cars which haven’t seen me when cycling! It is effective every time. Pros: Extremly loud easily gaining the attention of car users. Cons: For a bike horn- it is relatively large and obviously requires you having the bottle like compressed air container on the bike, which looks fine but is still quite large when looking at the bike. Also needs topping up after about 6-7 seconds of use- but this is very simple and easy with a standard bike pump it takes only a matter of about 20 seconds.

I can't avoid giving this product a good review because it is a great idea. In terms of positives - it is loud and it will get you noticed, unlike the buzzers and 'rape-alarm' style electronic devices. I don't recommend honking at pedestrians as it just seems to scare them rather than alert them. I would however recommend it for cars, lorries and buses so if you're a commute rider in traffic I'd highly recommend this. Whilst some others have alluded to poor built quality or materials, I don't think that is the issue here. I think it's just that the execution and design are flawed. But these flaws can be overcome with simple adjustments and a visit to a couple of aisles in Tesco. The issues are two-fold - the bottle and the attachments. Firstly, and not as seriously, the bottle is ever-so slightly too small to sit comfortably in the average bottle cage so I recommend using the velcro that comes with it to improve this to avoid the bottle jumping out when going over bumps or generally rattling about. Alternatively one can slip it in to a bottle holder. and then in to the cage for a more snug/stable fit. Secondly is the trigger and horn itself. 1. Two white plastic screw-on handlebar attachments are provided. These would benefit from actually being black and having some form of grip to them because, as most people know, plastic on metal or plastic on handlebar tape is extremely slippery i.e. when pushing the trigger, the horn just moves round the handlebars. This can be remedied with a rubber insert or some torn up sandpaper (if on handlebar tape). 2. The horn sits underneath the trigger and hangs down about 2-3 inches. If fixed to the horizontal part of drop-bars, it gets in the way of your knees when cycling. Besides an alternative mounting point, there's not really a way round this. What this system would really benefit from would be separating the horn from the trigger, allowing the horn to be mounted elsewhere (out of the way) and allowing the trigger to be more practically mounted. You'd then just need to be creative with the air-tubing. 3. The way the horn/trigger unit clips to the handlebars is extremely poor. As mentioned above, your knee even grazing over the horn will cause it to fall off as will going over even the slightest of bumps. This can also be dangerous as it can fall in to your front wheel. The way to avoid this is to wind the tubing round the frame or use the supplied cable-ties... which kind of defeats the object of having the horn just clipped on i.e. being able to remove it all together when leaving the bike. . This issue however can also be overcome by using self-adhesive velcro or some other form of removable adhesive. The point with all these workaround is that we shouldn't have to employ them. Looking forward to a 2.0 version of this product with the kinks worked out.

There are tons of “electronic bike horns” out there with higher decibel ratings. I watched some YouTube videos and they all sound like rubbish fire alarms. I know as a cyclist, a driver and a walker, I am tuned to respond to a horn. THIS DOES THE JOB!!! People in cars with their windows up, pedestrians blundering into the road or cycle path - they are all alerted by this beast. I’m sure it’s louder than the decibel rating. It’s incredibly loud and incredibly effective, and has saved me from countless emergency stops / crashes in the short time since I bought it. It weighs next to nothing and takes air from a bike pump for power. 100% would recommend to anyone.

FANTASTIC, arrived fast, easy to fit, velcro and cable ties make it a firm addition to the most rugged mountain bike and the filler/horn button attach nicely and firmly to the handlebars with a double click to ensure a tight fit. Neat compact design meas that I like other air horns, it only occupies a small space under the handlebar, not at all obtrusive. The sound has to be seen, (the reaction from everyone within 100 meters), and heard to be believed. I have had loud 12v battery buzzer horns before, but this 120Db baby is another level. Think football air horns without having to buy compressed air. Evens up the score for anyone on a bike in a commute!

Imagine having to deal with pedestrians. That word alone already gives me frustrations and seeing how loud my friend's example is I decided to get one so I can piss off those who piss me off. However, it is so loud that prolonged horning can cause hearing loss to even the user, so it will be a last resort.

Luide hoorn, eenvoudig te monteren op de fiets. Voldoende installatiemateriaal meegeleverd (tie-wraps, velcro, ...). Slang lang genoeg om fles in onderste drinkfleshouder te steken. Klein minpuntje: de slang zit al door de krul van de hoorn (voor mijn configuratie net aan de verkeerde kant), om dit helemaal netjes te krijgen, moet je de slang demonteren, daar begin ik niet aan.

Se siente de buena calidad, sonido bastante fuerte, fácil de usar e instalar. Pros: - Sonido bastante fuerte, me escuchó un autobús que tenía todas las puertas y ventanas cerradas. - Indispensable para "hacerte notar" frente a cochistas distraídos. - Es divertido asustar cochistas distraídos en tus trayectos diarios. Contras: - Recargarla es un poco tedioso, aunque aclaro, no es difícil y dependerá del uso que le des la frecuencia de la recarga.

The Airzound is probably the best bike horn you can get. It's really loud, all cars and trucks and whatnot will hear you. I don't even use it at full blast because it's too loud (there's a volume knob!). Recharging the bottle in air is easy. Installing is easy too, although harder than your regular bell as you need some space for the bottle and route the tubing in a way that it won't bother you while riding. The tubing is the part that I'm not sure about. It's small and feels nice, but I'm not sure about its durability. The instructions mentions that you should put a UV protection on the tubing. So I'm thinking it can get old and become brittle and cracks, like plastic tubing often does? But it's too soon for me to be sure. Anyway, still a very good product!

Bardzo polecam ten produkt i sprzedawcę. Przyszło szybko, montaż łatwy. Świetnie się sprawdza na drodze. Piesi w końcu słyszą, że nadjeżdżam 😁
