New to cycling and fixed gears

Hello,

Recently I’ve been very interested in getting a bicycle to weekend commute and just enjoy riding as a hobby.

I’m intrigued in going fixed gear due to the simplicity and more budget friendly option. After trying to research I feel very lost and overwhelmed on where to even start.

I was thinking about slowly building up my first fixed gear bike, purchasing a used frame, then slowly getting the remainder of the parts for it after. The problem is I’m unsure what I should be looking for and what I need to consider for each part in this build.

Can anyone give me advice and some guidance on how to go about just starting to get into cycling?

Thanks,
