Hello everyone. I'm new here and really happy this thread has been posted as I'm in the nursery still. Bike security is one of the reasons for joining up. I am currently designing custom build fixies with security in mind; not to mention that they are hopefully going to be stylish one-offs. Whilst discussing my designs with a friend last week, the inspiration and imagination was flowing nicely. By a bizzare coincidence or syncronicity I came up with the idea for secure bike parking in London theft hotspots. Bethnal Green sprang to mind initially. My idea was a little less techie than the bike tree. It could be much simpler. Electronic swipe cards or key pad passwords (mabe both incase you lost your card). Once inside there would be traditional bike stands to which you lock your bike to. Cost wise, if it was funded for ground rent, elec, CCTV (yurgh) etc. there could be a pay as you go system. With a dedicated web site one could simply register themselves and their bike(s) before being able to get a card. ??? Ride safe all !!!
