LOCK8 smart bike lock

this is pretty cool; it has a built in alarm and GPS tracker. It can also facilitate you renting your bike (because it's keyless), so you can earn money renting out your bike. And no charging as it recharges whilst you cycle.

Also check out skylock. http://www.producthunt.com/posts...

There's also http://teolock.com/ and http://bitlock.co/. Not sure about world's first!

I think one of the key advantages is that this has an inbuilt alarm/siren also.
