I have had quite some bicycles, and I have replaced everything on them. Including frame, front fork, wheels, steer, axles... I'd like them to be more durable.

I have had quite some bicycles, and I have replaced everything on them. Including frame, front fork, wheels, steer, axles... I'd like them to be more durable. Regular maintenance on the chain and gears should be done twice a week in fall conditions. In winter, this is true too but since we salt the roads, you must also clean chains at least weekly. Less maintenance simply wears of the chains much quicker. I think I replace them around 3-4K KM, but I have no exact numbers here. Lights break about every month when commuting daily. Batteries go empty, cheap lights break because bumps, charging them is a hassle. I'd like to throw my bike from 2 meters down and know it's not broken anywhere. In the city, people fight for parking spots and play rough with others peoples bikes. I want a mapping system which is safe and usable. I know it can be done, but is has not yet been done. I'm thinking integrated sounds & lights in the steering wheel. I have seen some interesting kickstarter projects trying to solve this problem.
