Planning to Buy a new bicycle. Need the community's suggestion.

Firstly, hello everyone.

As mentioned in the title, I am looking to buy a new bicycle, but I don't know anything about what's wrong and right here.

I have been here for 2 years now. I LOVE IT. but I am planning to explore the province and use it for day to day commute. Car is my least best option.

I rode my grandfather's bicycle (which is around 30lb) for the last 12 years back in my home country. But, that's it.

My budget is around 1.5k to 2k. All road bicycles. Any suggestions, please? Thanks in advance.

Edit: Thanks, everyone, for the suggestions, and I also read a lot of reports regarding bicycle theft. So, I will be going used bike as well as a lesser price as of now. Thanks again! Cheers!
