First ever time working on/building a bike

Hi everyone, I'm looking at bikes and it seems difficult to find one that suits what I'm looking or exactly in my price range.

If I was to get a frame and forks and then build the bike as a single speed/ fixie (so no gears, nothing fancy) using second hand parts does anyone have a very rough idea of the cost or if it would be possible to do for under £150. I know this is very subjective but if anyone has done this could anyone give me some tips and a rough guide of how much it cost them I would really really appreciate it!! Thank you so much!

Oh and I have a good range of tools already because dad works on his car a fair bit, so that wouldn't be a problem, unless I'd need any very specific tools!

If you post a wanted ad along those lines on here, I'm sure people could get you the relevant parts for around that, provided you were willing to go and pick them up

Thanks for the advice, really trying to gauge how feasible the project would be before buying the parts, just to make sure I can definitely finish the project and not be left with just half a bike!

Mmmm... you'll find the cost adds up buying them individually, so if you can buy e.g. wheels with tyres and a cog on, cranks with a chainring on, bar, stem and lever combos, etc., you'll make your money go further.

pesky piddly things like chain, tyres, cables, grips etc. add up in the end.

Ahhh see these are the things I needed to know haha! Thank you for the advice!

Update - Have just bought an Ambrosio pista so I'm not going to need to build a bike, however it may be a fun project to undertake should I get hooked on cycling so any info still welcome!

Does it have a front brake and foot retention? Unless you’re only going to use it on a track you’ll need those things over anything else. Especially if you’re a bit new to it all

Fortunately yes! It has a front brake and I'm planning to get some straps as they seem the easiest to use! Thanks for the advice!
