Why does riding a bike make you want to pee so badly?

Bear it gets me as well, no point in me getting a bike which can travel intergalactic miles on one tank as I need one after about 100 miles anyway.

The Vibration from the bike can cause irritation of the bladder , it fills itself with fluid to make you go for a pee in the vain hope you will flush the irritation . Cold can also make you want to pee for some reason that escapes me .

To put it simply.......

In the cold a person will have to urinate from cold diuresis - A condition where the surface blood vessels constrict in response to cold. This constriction causes greater volume pressure in the bloodstream which is detected by the kidneys. The kidneys will "pull off" the excess fluid to reduce the pressure. The kidneys then excrete the fluid, causing the bladder to fill. This is one way in which the body protects the amount of heat lost at the surface) a full bladder can mean additional heat loss. Urinating will conserve some heat.

That was it , I`d heard that before when I complained about having to stop every 20 minutes when I was mountain biking in the winter , the theory of it all had escaped me in the mists of time , or was that the steam of Urine ? ..... I forget

Those on last years AR may remember me "marking" one of the junctions while marking one of the junctions, too...

it normally just makes me horny !!! lol

Umm not too much of a problem, I tend dehydrate when riding anyway. But if you want to pee lots dive me trust, I would take on about 1/2 litre of water before a dive, the first thing I do when I come up is make a run for bog. You have never seen someone dekit so quickly out of suba gear before (its to do with change in pressure, how it acts on the body)
