What's the best way to positively identify your own bike? I engraved my son's name on his BMX underneath the bottom bracket and on the head stem, but I feel this may be a bit harsh on my new roadie. Are there more astatic ways of marking one's own bike?? powinc
Just a couple of ideas (not sure if feasible): 1. Security companies use a special pen to write info like the driver's licence on goods. The writing is almost invisible but the ink will light up with UV. 2. HSV uses a similar technology (I think) on their cars. They call it DNA. Hope this provides some clue to start with. Cheers, Amir.
A personal fave of mine is to make your bike as weird or unappealing as possible to thieves. Another alternative is to contact your local neighbourhood watch, who should be able to engrave a license no. prefixed with a state letter under the bottom bracket. http://www.neighbourhoodwatch.com.au If you check the above website for Victoria you will see its "Mark it in March" month.

I saw something in this month's Bicycle Victoria magazine that was basically some sort of transmitter that you put down the seat-tube. Im not sure how its activated but the idea is that you can identify your bike (and im guessing here but possibly find out where it is) through this transmitter. It's not heavy and it wasn't expensive... I will look up the details tonight if i remember... unless anyone else knows what im talking about? Cheers, Troy
What about some sort of medium-powered transmitter that sends a specially-coded beacon on a certain VHF/UHF frequency? Send it using code division to enhance the range of the device. It could be designed so that if it hasn't received an "unlocking code" from a device that you carry with you, for a certain number of hours (12? 24?) then it starts transmitting its signal, which should be detectable. Have it installed inside your frame so that it uses the frame as an antenna, and possibly have it inductively powered by your pedalling to charge a battery. This is all hypothetical... cheers, C3

People are talking about EPIRBs and transmitters... but... Do you just want to get some custom stickers for it or something? Depends if you want to mark it for ID after theft or if you just want your name on it to make it easier to find in a crowd? Paint some parts of it a strange colour, get those custom stickers made, i.e. your name on the top tube, maybe make some stickers that look like they are supposed to be on their but ID you somehow.. "POWINC STAYS" or something equally "marketable" - POWINC CRANKS - 20% More Power / 10% Less Effort Oh, you could try marking the frame "under" some other part - seatpost clamp, inside the dropouts, under the headset caps... hth hippy

Surely someone could get something like this in the space of a seat tube. They are small but squarish but tubes are long. Would work better than an ordinary transmitter.

I've got one of these in my bike which I bought when I lived in the UK. The one I have is a DataTag <www.datatag.com>. It is unpowered but emits a radio signal with a code when the relevant equipment is held close to it. I think the problem here would be the "relevant equipment" part, apparently all UK police forces have the right stuff (probably supplied by the manufacturer) but if Australian police don't have it then the DataTag is effectively useless. There's a mention of them here <http://www.nrma.com.au/pub/nrma/motor/car- research/secure-car/secure-valuables.shtml> in reference to protecting cars, but the price is much higher than I paid for the bike version. I paid around about $70. Graeme

I think if you used one to track a stolen bike you'd end up with a seriously p*ssed off rescue service and with luck, a very large bill for wasted time. Graeme

I was sort of thinking outside the box. I meant the idea of one not actually one that calls for emergency response. What I mean is something a little better than a vhf transmitter.
I suspect that some form of modulation on the VHF band would be ideal, since the signal can travel further than higher frequencies. It doesn't have to be identical to an SES beacon. I used the word 'beacon' loosely. cheers, C3
Personalising your bike may identify it to you, but it's not really going to be enough if you want to legally recover it. Unfortunately, I don't think there's an easy answer to all this. Any determined thief can remove/destroy the transmitter or unique markings. cheers, C3
Why wouldn't it be enough? How else do you get stuff back? "Yes officer, it's the one with HIPPY written down the side and the picture of the semi-naked chick on the toptube". If the stickers are still on it after the bike is recovered - why wouldn't stickers be acceptable to ID the bike? It's not like bikes are like VCRs, where every one of the same model will be the same (barring that incident with the yoghurt and the leaky garden hose...) hippy
Yes, but you haven't seen my bikes. Like my lovely little road bike for short/medium distances, why steal something with 150mm cranks & cotter pins? Have different bikes for different purposes, don't leave the expen$ive ones on display or out of sight too long for potential thieves to tamper with. Timely story from CNN: GPS bicycles used to bait thieves Wednesday, March 10, 2004 Posted: 11:58 AM EST (1658 GMT) http://www.cnn.com/2004/TECH/ptech/03/10/bikes.gps1.reut/ AMSTERDAM, Holland (Reuters) -- Amsterdam police will use bicycles equipped with hidden GPS transmitters to bait thieves and track them down in the latest effort to stamp out rampant bike theft, a police spokesman said Tuesday.

Yes, but those POWINC cranks are pretty unusual... -- "I'm proud that I live in a country where witnessing two hours of bloody, barbarous torture in gloating detail is considered indicia of religious piety, whereas a mere second gazing upon a woman's breast is cause for outraged apoplexy."

How close does the scanner have to be to detect the transponder?

I assumed (obviously incorrectly) that those types of beacons were made to have an excellent range (funny how misconceptions grow). Food for thought though. Since I like canyoning and the like I was always thinking of buying an EPIRB or whatever they are called but if there is something with better range that uses VHF then it sounds like a waste of money driven by media hype. Cheers Pete
The ones I saw were being distributed here in Oz (of course, I didnt remember to up the name) and were around $40. Must remember to look over the weekend. It seemed like a great idea but like you say, it all depends on how available the "relevant equipment" is... Cheers, Troy
Unfortunately, the device I described in my original reply to the parent was completely imaginary. I am only proposing what I think a good bike beacon would be like. Or at least as good as I can think of, with the technology currently available. If there is a market for this, it may be designed by some company, and sold. I suspect there isn't enough demand to make this sort of device profitable. cheers, C3
