So I constantly have this problem where my moped feels like it’s galloping and bouncing up and down as I ride I can re adjust the wheel alignment and it fixes the problem but it eventually comes back any tips on how I can, align it better with more accuracy? Or if it’s a totally different problem all together. This has been extremely annoying since it makes my peugeot very unpleasant to ride.
Bent rim ?
Is your tire seated properly? Or is it old, cracked and separated?
The seat is fine
that sounds like it could be plausible. How do I check?
Old school, lay on belly with a string from front to back wheel and sight down each side.
Is it variated?
If so that is "the goat"
Its from too weak of a spring
Yes it is variated
Then try adding preload to the spring. Is it kitted?
The goat feels like a bucking bronco as if you were riding a goat that was pissed offand it sucks to ride.
Do you have a launch lever?
If so, by holding the level slightly it will stop the engine bounce that causes this.
It also could be that your chain is kinked and it's jumping teeth (edited)

Yes I do something pretty much the same as that with every new to me used bike I got, I was surprised how far off wheels, swingarm and frame were off on many bikes,
It’s hard to get a 40-year-old moped that was never downed or involved in a crash of some sort before not to mention left the factory/dealer not perfect when new or Serviced
It’s decently kitted by this forums standards since I’ve heard of these things going like 70mph. Mine goes about 51mph and I do have a launch lever so I will try it out on the way home today. I will also try the “old school method” and see how that goes. I’ll send an update this afternoon.
If it's still the stock spring with a stock preload you're probably goat'n it.
I aligned the wheel and it’s so far so good I found that it’s a little bit of both because once I get up to 40mph it starts feeling smooth again. The only thing that annoys me is it seems like I have to align it every week.
Well, does the bike have some kind of threaded wheel adjusters?
If so there should be no way it changes alignment.
Pics of rear axle and wheel?
It does and I’ll send pics after school today
yea that's not something that changes, is the axle nut loose? tensioners slipping? What's the bike? chain fiunal drive? maybe the sprocket is offcenter, tugging the wheel periodically out of alignment and also making a leaping surge feeling?
Axel nut is fine and so are the tensioners but how would I check the sprocket? Also it’s a 1970 Peugeot 104.
I would bet your wheel is out of round. I had two wheels out of round and it felt like a galloping horse. Not sure why realigning periodically would help but what your describing was due to out of round wheels; for me anyway. Hope that helps!
Check the sprocket by spinning the wheel and holding a pencil, screwdriver, stick, whatever, right above the teeth. As it spins, check the gap between the teeth and the stick.
You'll notice if it hops up and down.
But that wouldn't make your wheel hop. It'll just mess with your chain tension. And they all have a little bit of out of round-ness.
It's the wheel or tire that would make it hop. Or a severely bent axle.

I can tell you, for fact, if your wheels are out of round enough like mine were it will absolutely move you up and down like a hopping, galloping horse.
The wheel won't leave the ground but it absolutely makes you feel like you're bobbing.

That's not what I typed. Having a sprocket out of round a little bit wouldn't make your wheel hop.
But a flatspotted, or bent, or egg-shaped wheel would definitely give you a hoppity horse ride.
