I have learned one thing with keeping bikes is not to leave them in the rain (the hard way though
But apart from that Usually a good thing is to check the tire pressure weekly as that really makes a difference for me.
It is recommended to lube the chains after couple of weeks, remove dirt from them if you ride a lot off road that is.
One another thing is to keep a watch for brakes. I dont know where you got the bike from , but a lot of times if its not from a bike store there can be problems in the way it is assembled. Sometimes the brakes are not tight enough..that happened to me but I requested that they make sure they were. I have recently gotten a bike with disc brakes..sure is a lot of difference for me.
Also if you 'd like you can get seats from any store like target and replace the existing one for more comfort.
