If it truly is a vintage bike - don't.
Whatever value it has will disappear when you hack it up.
But If you insist:
Start with finding out what kind of dropouts you have.
Only bikes with (semi) horizontal rear dropouts are good fixie candidates.
Next check your rear OLD - Over Locknut Distance. Basically the width of your rear hub, the distance between the rear dropouts.
Then go shopping for a fixie rear wheel with the same OLD.
Install fixie wheel. Check what your chainline looks like.
If you have a double crank, you might get a better (=more parallel with the plane of the frame) If you use the inner chainring.
If that doesn't give a tall enough gear you might have to shift the rings around. Or swap to a Single-Speed crankset and a shorter Bottom Bracket.
Once happy with that, fit chain and ride.
Any bike can be turned into a fixie, at varying degrees of difficulty. But if the rear wheel can be moved back & forth to adjust chain tension it'll be so much easier.
Buy a rear wheel that can take a fixed sprocket. Mak sure the spacing fits your frame width. Tinker with your crank and/or the wheel centering to get a good chain line. Install new chain. remove derailers. Ride.
If you have a mach bike, go to mauville to change to an acro bike. when the road is straight, just ride in that direction. when the road stops, press B + the direction you have to turn together to jump to the next pipe.
Depends entirely on what you think of as a "normal" bicycle wheel. An externally geared wheel is unlikely to work very well, as it has a longer axle and will require a wider dropout spacing than a fixie wheel. On top of that you might get into chainline and gear ratio issues, not to mention that the fixie chain might not sit comfortably on multi-gear sprockets. If you get the urge to turn the fixie into a geared bike, there are a bunch of brackets and attachments that your frame will be missing which will have to be sorted out. A wheel with internal gears is more like to fit both dropout width and chain width, but again using those gears will require some work. Replacing a fixie wheel with a single-speed wheel is usually easily doable, they tend to be a direct fit.
in mauville city your choices are a mach bike (very fast but hard to turn) acro bike (a bike that is not very fast but easy to turn and you can do stunts with it)
no i cant turn a 50cc pitbike into a 125cc pit bike the bike will blow up .
why racing bike bends inward while talking a turn? answer
A lot of times, merging into a turn lane may require you to cross over a bike line, or the turn lane may be jointly a turn lane and bike lane.
Yes, it would be possible to turn a regular bike into an exercise bike. The way that this is done, is by mounting the bike at a level where the wheels spin, but the bike does not move. You can do this by welding metal onto the bottom of the bike, and elevating it.

Well first off you lean with the corner, Do not turn the handlebars at all, as a matter of fact start off on a scooter and then learn from that i hope i never meet you on the road
