As to that saddle lock? It's much easier to change the seat post bolt to an recessed hex. A thief would need an allen wrench to steal the seat & post. I seen plenty of bikes on campus minus the seat & post. A proper bolt instead of the quick release would slow down the thieves who only carry vice grips. Or clean your frame out and install you seat post with jb weld instead of grease.
Did you watch the video? The point of the Seatylock
isn't to lock the seat -- the inventors have turned the saddle and saddle rails INTO a lock that can then be used to lock the bicycle itself, hopefully to a fixed object like a bike rack or sign post.
How much vs a normal seat & post?
Of course it costs more than a "normal" seat and post, and probably more than a normal seat, post, and a quality lock -- BUT it offers the same sort of convenience as the pedal lock that started this thread. It's always with the bike, so you can't ride to the store and
then discover that you left your lock at home. (It's also probably not as secure as some higher end locks, but again, it's about the convenience in lower-crime neighborhoods.)
And do you really want to have to adjust your seat every time you unlock your bike?
The nice thing about that design is that you don't have to adjust the seat each time you use it, since the seatpost itself doesn't move when the seat is removed. It also means that the seatpost itself can be secured with a normal bolt, preventing theft of the post.
What's to stop the pedal lock from being removed with a wrench, thereby unlocking the bike ?
If the cable comes out of the pedal, goes through the bike frame and/or wheels and/or around a fixed object, then locks to the pedal again, how is that any different than a normal lock?
Normal locks don't bolt to the bike's cranks, but they still do a decent job of locking the bike.
