The Cardo BK-1 is a helmet-mounted communication system that allows you to talk easily to a ride partner via Bluetooth – but the big question is whether you really need it. If it does appeal, you still have to contend with a hefty price.

I found setting up the system pretty straightforward. It takes just a few minutes. You use a Velcro strap to attach a cradle to the vents of the helmet and then snap the BK-1 unit in place. Then you attach the audio kit – which consists of two speakers and a microphone – to the helmet via Velcro mounts. I tried it on a several different lids and it was simple every time.

That's it. Then you just talk and the person (or people, if you buy an additional BK-1 Single Communication System for £195) you're connected to can hear you and talk back, just like a hands-free phone headset. The system is voice activated so it will shut down temporarily if there is radio silence for 30secs and come back to life when you start talking again (you can disable this feature).

The obvious worry was that the system would affect our ability to hear traffic sounds, but the speakers hover close to your ears rather than sitting right over them so they don't block other noises, and the microphone is foam-covered so you don't get the sound of the wind blowing over it. If someone is actually talking, it's only as loud as if they were standing next to you and chatting. Personally, I didn't feel that the system compromised safety, although you're naturally free to disagree.

The bits that mount to each helmet total 120g – so you're adding maybe half as much again to the weight of the helmet. I did notice that weight to begin with but soon got used to it.

One benefit to using the BK-1 system is that you can sit one rider behind the other and still talk. And usually when you're cycling fast, even riding side by side, you have to turn and/or nearly shout at one another to make yourself heard; that's not the case here – you just talk normally. You can be up to 500m apart and still communicate although that's in ideal conditions. If there are buildings or trees in the way, it's far less.

As well as two-way (or three-way) intercom function, the BK-1 can act as a Bluetooth headset for your mobile phone, allowing you to make or receive calls either by voice command or by reaching up and pushing a button. You can also use it with an MP3 player (let's not get into the rights and wrongs of that just now) or GPS device.

The BK-1 unit is waterproof and the Li-polymer battery provides up to seven hours of talk time. It takes three hours to recharge fully from empty.

All in all, the system works well. You might occasionally get fed up of your ride partner's heavy breathing in your ears up a steep climb, but it's easy to adjust the volume and the speakers are on flexy mounts so it's easy to move them away.

But I'm struggling to see much need for this system – in motorcycling, yes, but cycling? Don't get me wrong, it's quite good fun to use when just going out for a ride with a friend, but £335 worth of fun? Well, you have to decide that for yourself.

The BK-1 has won a Red Dot design award so maybe I'm wrong. I guess if you're in a two-up event, for example, they could be handy. If you think that they'd be useful for any other type of riding you do, fair enough, the system will perform as promised.

Verdict

Bluetooth system allows you to talk to a ride partner over several hundred metres - but an big outlay for an uncertain benefit.

Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

Cardo say, "Meet the Cardo BK-1 DUO, the world's first Bluetooth Cycling Communication and Entertainment system. The Cardo BK-1 offers simultaneous conversations via intercom between up to three cyclists, mobile phone connectivity, in-the-ear instructions from GPS devices and MP3 stereo music streaming from compatible devices. Whether you cycle alone or in a group, the Cardo BK-1 will give your favorite outdoor experience a whole new dimension."

The system works well, I'm just struggling to see a real benefit for most people that would justify the outlay. If a two-way communication system would benefit your riding, this system works well.

Well, there's nothing to compare it with, really (not that I know of, anyway). it would be good if the unit was a little lighter and less conspicuous... but you could say that about a whole lot of things.

Adding 120g to the weight of your helmet is noticeable, making it just a little less comfortable to wear.

Tricky one to judge but I think £335 is a lot to pay for something that makes communication just a little bit easier.
