"I like the idea of the saddle lock. In my opinion the designers have limited their audience having the saddle locked to one  bike purpose built for the invention and should have looked at applying this concept to standard built bikes instead of custom.I too had a similar idea back in 1997 . Unfortunately due lack of research on the internet I was scammed. Enough of the rant.It interesting to see the ideas and concepts available today regarding bike safety and security.I spent a lot of time trying to get my product recognised. Thanks to the internet there seems to be more scope to do so.Mike"
