Bike Spike- Theft Deterrent.





Introduction: Bike Spike- Theft Deterrent.


Bike thieves are a pain in the bottom; I thought that I would get my own back.

Ladies and Gentlemen, I give you  . . . the bike spike.

When locking your bicycle in a dodgy area simply remove your saddle and replace it with the bike spike.

Please read on  . . .

Step 1: Materials and Tools

A piece of wood and a chisel.

I took a piece of my Eucalyptus firewood.

Step 2: Making

I removed the bark and sharpened the stick into a point with a chisel( I also used a surform but it is not necessary).

I tried to stop myself but I could not resist putting on the inevitable blood splash.

I added a rim from a drinks can just to finish it off.

Step 3: Using

Given a choice of bikes to steal it would be insane to steal the one with a big, bloody spike on it.

"They don't like it up 'em ".

Maybe I'm fooling myself but at the very least it gives passers-by a smile.

Happy Riding ( remove the spike first).

    Legalities aside, what's to say someone won't just do a stand and ride. Peddling it without sitting down.

    The risk of you hitting a bump and then getting knocked into the non-existant seat for one thing.

    Don't panic!

    Maybe just a THREADED―sharpened or not―piece of chisel wood of about 3 feet long that when riding goes on a holder (like surfers use to carry the surfboards. It wouldn't be a booby trap because is obvious to anyone, but the deterrent would be the time spent in undoing the stick. A thief needs the time to undo the thread.
