Kickstarter Campaign to fund batch production of a Bicycle Movement Alert

I still think a good lock is a better solution.

but surely,

were you to lock your bicycle outside a cafe or public house, with a good lock, (e.g. a Kryptonite lock with a Sold Secure rating Silver or Gold), then be positioned in that venue with your gaze away from your bicycle,

it would be useful to know if the bicycle/lock moves to an extent which suggests somebody might be in the process of attempting to break your lock?

(as i for one would find this useful, as i'd go outside and investigate what's happening - hopefully being able to intervene via negotiation to prevent my bicycle from being stolen!! - which was the whole impetus behind building a working prototype, and attempting development of the idea via open source product development..)

ps., did you see this post? :-)
