I am looking for a new bike with following properties:
- comfortable for commute, promenades and fitness in the city and outside with occasional bad roads (dirt roads with some tree roots, bumps) and rough cobblestone
- more or less light (I expect to go upstairs with it in hands often)
- upright posture preferred if possible
The thing is, I don't want to buy a compromise that tries and fails to be everything -- hybrids are seen this way in some articles I've read.
So I am looking at the three categories I mentioned in the title. Can you give a comparison of the three? What can you advise? Are my criteria too broad?
