Would they allow you to use mapamobile for a bike though? I could see them saying no as the number of kids that go missing is pretty low compared to the amount of bikes? Otherwise Im gonna do this I reckon, I gave up on trackets tbh if the bike gets nicked its nicked and thats it, I onyl use a disclock nowadays and a cover to 'hide' it, I have an R6 and not stolen yet after 8 months commuting. (mind you its not parked in London)
