Bottom bracket/crank spindle

bazcarnegs:
Hey, fairly new to the whole maintenance side of things. I’ve been out practising stuff on my bmx and had a little try if my friends, his pedalling was so much smoother and “grind free” so I’m looking into replacing some parts. I’m not sure exactly what I would need to replace, is it common to replace bottom bracket and crank spindle at the same time or is one more prone to wear than the other? I’m not 100% on what both do truth be told. Just putting out the feelers to see what’s what at the moment. Any help or advice greatly appreciated. Thanks in advance.

What set up do you have, One piece cranks or three piece cranks?

How do I tell the difference? Sorry noob here
It’s a fitbike if that makes any difference?
