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).

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

    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.

    Funny but illegal. It falls under the booby trap law. Not to mention if someone fell on it ud be in serious trouble! But still funny.

    Everything in plain sight. You steel it. You ride it, You ouuuuuchhh!

    Impracticable, but ...... niiiiiiiiice!

    HA Believe it or not, I once had a seat stolen off my bike. The bike was locked up securely but the seat had one of those quick disconnect levers and someone stole it. I took that lever off when I put a new seat on.
    You would be surprised how difficult it is to ride a bike without a seat.

    This is why you should never ride your bike when drunk.

    This is seriously funny.
    Tempting, very tempting.
