Ok... at this point I think I have read so much that I am simply confused.  This is what I want.  I want to spend $2k,  I want to ride both on paved surfaces and light, beginner type Mt bk trails.  I will be climbing some fairly steep hills at times.  I may like to do some very long rides and overnight type excursions(but that would be rare.). Most of the time, I will be riding for fun and exercise.  I rode an ebike in Portugal and it was the best time I have ever had cycling.  I am 5'4".  Ive looked at a ton of bikes but damn I get lost in the tech talk.  I do not want to have to perform complicated maintenance.   Can you give me some suggestions?
