Obv for building bike stuff, tig is the ticket and when I mentioned bike stuff one of the tutors said he's get me onto tig asap but I've heard that when you are learning it's actually better to stick to mma/stick because getting nice/good results with it is harder so you learn quicker. If you can stick weld nicely then you can probably mig and tig nicely but the opposite not necessarily true if you see what I mean.
From my very limited experience stick welding is harder than MIG but easier than TIG. So it´s probably a good start. It´s tricky to stick weld material thinner than ~1,5mm without burning through but it is possible. I welded track ends to this gas pipe bike with a stick welder (crap photo):
We can do mig, tig and mma or stick.
