It's a tough recommendation to think of one material for both bike riding and working. If you want a leather for working in, I'd recommend a medium weight horse or steer - any thick leather will really tire you out, especially your shoulders and inner elbows. If you get a medium weight hide on a slightly oversized jacket, you can just wear motorcycle armor underneath when you want to bike.
On the other hand, many people want a very heavy leather for riding - flexibility can be sacrificed because you are basically holding one position on a bike.
I would not want to be doing outside work in any 6-8 pound piece of thick hide that can stand up on it's own. Furthermore, you may want to get a bi-swing back or armpit gussets to make it more movable. Frankly I think a chrome tanned horse or steer would be great for shedding water and wind - though I suppose in a downpour the water would eventually soak through.
I'm six feet and 150lb too, and I used to do construction in the mid-west, so that's my 2 cents.
