Bicycle frames

hey, im doing a survey for my bike alarm. How thick is the biggest frames on your bike, and how thick is the smallest frame? a reply would be very helpful. Thanks

Thick as in the metal inside a frame? On my bike, a very thick street bike (stunt/bmx whatever you want to call it), it is .049 throughout. And that is thick! The frame weighs more than 8lbs (for a 20in bike) I would say your standard bike is .035 or less throughout, probably less for a cheap mountain bike.

He's attaching an alarm to one of the tubes of your frame, Matt. He doesn't care what the wall thicknesses are. He needs to know what the outside tube diameters are.

lol, ok thats what I thought originally, but I thought that information was easy to get.
My frame:
top tube and down tube are 1.5"
seat tube is 1"
downtubes (rear triangle) 3/4"
