Bianchi Kuma 4600/5300, Bianchi Camaleonte Cross or Cube AIM

[Kupepe]

Good evening and thank you in advance for replies. I am interested in buying a bike to start cycling again. My aim is to start doing distances on road by the shore line in the city I live and possibly at winter to do some off-road cycling when stamina is up. Main use is gonna be workouts in the city. I am 1.92 cm and the height of my crouch is 33.9” . Due to style and after some research my attention is caught by these bikes

Cube AIM

My price range is going to be around 750-850 usd .

Should I be concerned with the camaleonte weight? It’s almost a kilo heavier and that is without having to use discs as breaks in the future. I like the fact that it does not have the huge tyres of mtbs and that will allow better cycling in town while it has a front suspension.

Any suggestion?
