I get the instructables newsletter twice a week,
and this was one of the features in Friday's newsletter
Used to have a marine air horn on my touring bike, held on with hose clamps, when I lived in NZ. That used to get there attention if they came too close or cut you off.
I wouldnt try that riding through the Southern Alps...you'd get Keas trying to mate with your bike.
Some bugger nicked it of the bike in Greymouth. Perhaps they wanted to try there luck with the Keas?
Like the idea, might try it. Instructables is good - any site that has pages like "how to build a van der Graaf generator out of an old sewing machine", has to be good!
My bike has the Bee Brand Chinese Revolving Bicycle Bell - rings very loudly, you keep pushing the presser, it keeps on ringing and ringing ! (that's the revolving part).
On organised rides, you'll see Mum and Kids by the road, waiting for Dad to ride by - passing time, waving to other cyclists. If they wave at me, I always give the Bee Brand Chinese Revolving Bicycle Bell a good ring - gets a laugh every time.
And talking of organised rides, the Mutual Community Challenge Ride during the TDU went past the end of my road. I had a darned good look at the handlebars, to see how many cyclists, had fitted the mandatory Warning Device. Lots of heart monitors, cadence meters, GPSs, tri bars, mobile phone carriers, extra water bottles etc. But on those 2000 handlebars, not one bell or horn did I see. Not even a small one. Not one!
I'M the madatory warning device on my bike. If you cant see me coming in my coordinated Biacnhi bikewear then you must be blind and you shouldnt be on the road.
These day I've started to whistle quite loudly to get car drivers attention if I think they are going to pull out in front of me or cut me off. Has saved me a few times now.
i just had a couple of these delivered ...
hot tip: don't test them out in the office next to unsuspecting work mates :)
