The Bike Wheel Bow is a unique weapon made from an old bicycle wheel. Obviously this isn’t going to work like your typical bow. It is more of a bow-like-sling-shot, relying on the stretch of the string, which is rubber tubing. Here is how to make one should you find yourself with a bike, but need a weapon.
First you chop up a bicycle wheel and remove the spokes, until you have a semi circle. Then use some eyelets to make it look like a compound bow. Using rubber medical tubing with a section of bicycle inner-tube in the middle will give you a fold and let you shoot arrows without nocks.
Its creator Darren Hall says that the rubber tends to stick on the eyelets, so it might be a good idea to lube them up before shooting. Now you can make a weapon from a bike. Awesome!
