Without a bike intercom, bike riding is a solitary experience. When you're riding alone it's a good way to clear your head or get your thoughts together. But if you've got a passenger, or you're riding with another biker, inevitably you'll want to talk to them. bike intercom systems that mount in your helmet let you do that.
The problem is that there are so many to pick from in such a wide price range. It's hard to rule which one to choose. And given that bike intercoms have to work in an extremely difficult environment, choosing the right one can make the variation between enjoying your new buy or hating it. This bike intercom recap will hopefully make your decision easier.

Let's start with a broad summary of the types of bike intercoms available.
Acoustic bike Intercom
The most basic form of bike intercom is the acoustic intercom. By acoustic I mean that it doesn't use electronics at all. It just uses hollow tubes that your voice travels through. They're like the old ships where the captain yells down a tube to the engine room to tell them to "give it more steam."
These systems have rubber-tipped tubes that insert in your ear the same way an earplug would. There is also a mouthpiece tube for you to talk into and all the tubes connect into a junction box.
One of the positives is that there are no batteries or electronics to mess with. That makes them very dependable. However, there is no amplification which means there is no way to adjust the volume or filter out wind noise. So at higher speeds, it will be more difficult to hear. another problem is that some population find the "earplugs" uncomfortable in their ears for long periods.
Obviously these acoustic intercoms only work for rider-to-passenger and not bike-to-bike.
Wired bike Intercom
The next step up is wired intercoms. These systems have wires that run from the rider and passenger into a central control box that houses the electronics and battery.
Just like the acoustic intercom, with a wired principles you don't have to worry about any external interference like you do with wireless technologies, unless you add a radio handheld communicator for bike-to-bike talking to your system. Some wired units let you plug in an Frs/Gmrs radio, which is described in the wireless technology section below. The radio requires voice activation for it to work.
One of the issues some population have is that the wiring can be a small bit of a pain. Every time you and a passenger get on and off the bike you have to remember to unplug the units. Depending on how you have it set up, this could be two or three plugs.
Wireless Intercom Technology
There are four types of radio technologies used in the U.S. For bike intercoms. They are Gmrs, Frs, Fm, and Bluetooth. There are also wired intercoms that enable you to plug into a handheld Citizens Band (Cb) radio that has voice activation.
Frequency Modulation (Fm) radio is similar to the Fm radio you listen to, but for bike intercoms a narrower frequency is used. Like Fm radio, these systems can produce clear sound, as long as the distance between them isn't too great. Fm radio works best when there are no obstructions such as hills between the transmitter and receiver. If long range is the most prominent feature, then Gmrs intercoms will provide best performance.
The family Radio service (Frs) and the normal mobile Radio service (Gmrs) are the contemporary equivalents to the old walkie talkies you may have had when you were a kid. Frs radios typically have a maximum range of two miles with few obstructions in between, while Grms radios recap up to several miles. Like Fm, these are group frequencies so other population can hear your conversations and vice versa. In some heavily populated areas these Frs/Grms radios are heavily used, while out on the open road you should have fairly underground conversations.
One nice thing with the Frs and Gmrs radios is that you can go to your local discount store and buy a cheap handheld radio that will recap with these units. If person were following you in a car, or they had a wired bike intercom principles that lets them plug in an Frs/Gmrs handheld radio, they can recap with you. The downside of this was just mentioned in that there are millions of these radios out there so in heavily populated areas you'll pick up lots of other transmissions. Also Gmrs radios need an Fcc license for legal use.
Bluetooth is the most recent technology to hit bike intercoms. Not only can these systems recap totally wirelessly from rider to passenger, they can be used to recap from bike to bike. Although with these systems the range is not in miles, it is in hundreds of feet. Since you are likely riding close to your buddies, this is not regularly a problem. Although, range can be as much as 800 to 1600 feet.
The Bluetooth range limitation unmistakably works as an benefit since it limits the estimate of surface interference you'll get. Also, since you must schedule two units to work together, you won't pick up conversations from other population with Bluetooth devices...and they won't be able to hear you. You won't have to worry about your conversations listened to by anything else.
If you want Bluetooth wireless transportation there is one thing to watch for. Some units that say they are Bluetooth use Frs or Gmrs to recap bike-to-bike and the Bluetooth is just used to recap with a Bluetooth enabled cell phone or other device.
Bluetooth intercoms also regularly have some other features you won't find on other types of intercoms such as:
Integrate with Bluetooth enabled cell phones and automatically acknowledge calls totally hands free.
Enjoy your beloved stereo music from your A2Dp enabled cell phone or Mp3 player
Listen to the audio navigation message from your Bluetooth enabled Gps.
Some Bluetooth intercoms only have one ear speaker while others have two.
Motorcycle Helmet Intercom Features
Here are features to look for as you are shopping for an intercom to use with your bike helmet:
If you may be riding in the rain, get a principles that says it's waterproof and not just water resistant. Some riders will put a water resistant principles in a plastic baggie and that works for them.
You can get systems that have a headset speaker for one ear or both ears. Factory and spellbinding the intercom to another helmet is easier for systems with only one ear, but some population want to hear sound in both ears.
Most systems have voice activation of some kind to keep the headset quiet when no talking is occurring. This voice activation often has the potential to be disabled and a push-to-talk switch used instead.
Many intercoms have noise discount capabilities with digital signal processing to help reduce the noise they pick up from the microphone. The faster you drive, or the windier it is, the more prominent this feature is.
If you want music, look for a principles that has a built-in Fm stereo radio tuner or an auxiliary stereo input for a Walkman, Mp3, iPod, or satellite radio unit. You can also use this input to receive driving directions from a voice prompted Gps unit.
Some systems mount on your helmet, while others have potential to mount on your belt clip or bike. If the principles is big and bulky, you may want the potential to mount it on your bike.
You can join some intercoms with cell phones so you can talk while you ride. They need special cables or you can get bike intercoms that have Bluetooth potential so they connect to your Bluetooth-enabled phone wirelessly.
Once you find the right bike intercom for you, it will unmistakably make your ride with other population much more enjoyable. You'll wonder how you got along without it. You typically get what you pay for when you buy bike intercoms, but even a bad bike intercom is best than none at all.
