it doesn't have an internal geared hub, it's a singlespeed only. upgrading would cost you at least 400 bucks, because you have to change the gates sprockets, so good luck with that.
Why have a CDN Belt with that gear ratio? It will break or slip sooner or later, especially in wet and cold conditions, when you go in full weight standing up ok the pedals… Been there, done that. Otherwise I love this bike … Price nowadays is a bit too high
