wait till you repack your wheel bearings.
I use butt juice to repack mine
how do you repack sealed bearings?
You replace them.
welcome to moped repair
I have seen needles that hook up to a grease gun. I guess sealed bearings can't be totally sealed and dust gets in
ok new bearings on my list now
where do you get these "bearings" you speak of? never seen em fs on ped sites. maybe i havent been looking.
Bearing shops.
local bearing shop had none here
If they are sealed you can either remove the dust seals. I have never seen true sealed bearings on a moped (where you can't get access to the actual bearings). spray em clean with carb cleaner till all the old grease is gone then repack them with a high temp bearing specific gease.
there are shops designated specifically to bearings? yet to see one around here.

I can imagine that conversation going well when the bearing shop dude wanted to open his store...
Any bearing with shieds on both sides are classified as sealed. tomos uses them on their axles. I would persume there are many other mopeds that had sealed bearings, but Motobecane and Puch seemed to have been stuck in the dark ages of using loose balls.
McGuires seems to be a nation wide bearing provider with locations in larger towns. There are others. Try the yellow pages
"There is also Mcmaster Carr":http://www.mcmaster.com . Thats where I found the sealed bearings for my Motobecane, spoked rims, my mags came with cone and cup bearings
Mcmaster Carr is the shit! I use them for all kinds of stuff for furniture projects. They get a lot of money from me...
Un-seal them, carefully pry the plastic up at one place and pull her out, wash the bearings clean and re-grease pushing the seal back on. No biggie.
You can't beat a new or OLD non-worn supple chain, tightened to the max with 5/16 sag avoids climbing up the teeth.
"sealed" bearings should really be referred to as "cartridge" bearings. Chances are you can get them at a good bicycle shop.
Here's a how-to for replacing cartidge bearings.

The only issue with that how to Bret is puch wheels have spacers between the bearings that have the same ID as the bearing thus there is no easy way to get them out. I don;t know about other moped wheels though.
Motobecane bearings can be removed this way.
im getting better gas milage too .
im so excited! new chain should be in the mail by tommorow! It may already be here by tommorow! as for the bearings, i dont feel like replacing them. too hard to track down. Can i just regrease them? I'm gonna have my wheel off too change my brake pads anyways, is it easy to regrease? I think i'll grease my brakes while im in there, too :).
i just bought my motobecane 2 wks ago and my chain snapped today - aauugghh - how difficult is it for a newbie to change the chain? do i have to change the bearings as well? - Thanks in advance
very easy..very easy just find out the chain size and it should be fairly obvious how it goes on...otherwise look up anywhere online about putting a bike chain on and its pretty much the same...
so no need to do anything w/ the bearings then right?
and not to sound like a complete idiot but can i just look up the chain size (1978 MB) or should i just measure the old one? thanks
its a 415 type chain. get one at quarterkick.com. they have the racing style in stock which is a bit more expensive, but im sure for a reason. then you pop it on, it will make sense. you may or may not have to remove links from your chain.
to adjust tightness once you have it on: loosen the two matching bolts on each side of the rear wheel. there up there in size.. 16 or 17 mm if i remember correct. that will free the rear wheel up for adjustments. then turn the small 8mm (you'll see which ones) bolts tighter/looser to bring the rear wheel forward/backard, which will loosen or tighten your chain respectively. make sure you turn the 8mm bolt on each side equally so that the rear wheel is STRAIGHT. otherwise you have a poorly aligned bike. then tighten up the 16 or 17 mm fat bolts when you've gotten where you like, and you're good to go.
