I would suggest going to REI and have a look at their offerings. I have a pair of their regular looking shorts that are "ok" for cycling. I balked at their pants offering but they seemed like they might work on a bike. It is pretty usual to see a cyclist wearing trousers or pants. I used to do that sometimes when touring but I had cycling shorts underneath. Eventually, I found it work bringing tights or legwarmers. The pants that I have seen have a tactical look with logos all over them. But REI seemed to have the best offerings.
