OP lives in a mountainous country so he basically had two choices: a 29er or a gravel road/adventure bike.

He chose well.

Cheap bikes are a waste of money b/c they're heavy, assembly is questionable and they come in only one size.

One pays more for a high quality bike but the satisfaction derived from owning a properly sized bike is something money can't buy.

And for people like OP, a bike is often the only practical means of transportation.
