I noticed a clicking sound that I could also kind of feel on my right foot when pedaling on my fixed gear bike after a crash. The bike is an Aventon Mataro which I bought used but with mostly everything stock.

I went to see a local bike repair shop which helped me tighten my crankset because apparently that was pretty loose and that helped a little but the click still exists when I push hard both when pedaling or backpedaling. Although the bike repair person was a great guy and said I don't need a repair until the problem gets louder/worse, I still have my concerns.

First, what are the potential consequences of riding with a cracked bearing in my bottom bracket? I would like to get my bottom bracket changed even if there aren't any big safety issues because a big part that I like about riding fixed gear is the silence but should I keep riding this bike at all before getting it changed?

Second, how do I change the bottom bracket on this bike specifically? I was looking online and found a bunch of information on all sorts of bottom bracket repairs but couldn't really pinpoint what category mine fit into (it should be the stock bottom bracket which happens to be a VP Sealed Bearing 68*103mm).

Third, if I were to replace this myself, what bottom bracket should I buy online that fits this bike and is pretty worth for its price?

Thanks in advance!
