I do have a secure place to leave it
If you are 300 lbs, I would NOT get a carbon bike. Even if you were 150lbs, I would still recommend an aluminum bike for commuting. Carbon is great but can be fragile in some situations.
And honestly, the different between a 18 lb bike and a 20 lb bike is meaningless in this situation.
