A couple of days ago I was about a few blocks from home when the rear wheel gave a tug of resistance and I suddenly began hearing a loud noise.

I pulled over and put the scoot up on the stand and tried to rotate the rear wheel by hand. It moves (it's not completely seized) but it feels rough.

I decided to ride it slowly home with the noise remaining fairly constant.

I'm assuming that one or more of the rear axle bearings self-destructed and have started to take their neighbors with them.

My shop is about 20 minutes away. It'll cost about $100 bucks to have the scoot flat-bedded to the shop.

My question is this: If the scoot can be ridden slowly, is it possible to do so in order to get it to the shop under its own power without;
a) endangering me?
and
b) doing further damage to the axle and / or surrounding area?

Don't mean to sound cheap, but I doubt anyone here would willingly light a $100 bill on fire if there was a reasonable alternative that would save it from the flame.

Ok, so first thing to do is check the rear hub oil to make sure it hasn't run very very low causing the issue. I have seen the rear hub lose oil to the point where your symptoms have surfaced. Have you checked it lately? If the oil is the cause, you may have damage in need of repair, or not! Know one can tell until you verify this. refill and try it out.

Probably more likely is a bearing is going/gone out to lunch. It sounds as if it's in the final stage of maybe breaking up.

I take it the rear caliper hasn't come loose and it's dragging the pads on the disc giving simialr symtoms??

Irrespective of what is causing the issue, I would not ride it for 20 minutes to the dealer. If something breaks, you could hit real trouble and come off the bike. Even if you don't come off the bike, you could do real damage to the hub gearbox and the housing if something shears.

If you cannot determine what the issue is, then $100 is cheap insurance to get it to the dealer. It's called protecting your investment, and you life. Good luck on this and hope it pans out ok.

Flat
Get it transported.

It's not worth the risk.

If it fails en route you'll be curing your decision.

As advised above you do need to do some more investigation before any judgement can be made. Firstly make sure that the axle nut has not come loose. If you grab the wheel with both hands is there significant play when twisted out of the vertical plane? Have the brake pads disintegrated? Does the rear brake feel like its working normally without any further noises? Its also possible that some grit has been trapped in the brake calliper, this can sound quite alarming.
If a bearing has failed its more likely to be the one in the outrigger which is exposed to water and dirt rather than the transmission side which is running in axle oil. If you are sure its the outrigger bearing it would probably do no harm to ride carefully. Otherwise it doesn't sound safe given the level of uncertainty.

Thanks all. Called the truck.

Don't want to be penny wise and pound foolish.

Did you recently have a rear tire changed?

No. Interesting question. Why do you ask?

So, as suspected, the rear axle bearings looked like the morning after an epic frat party when my mechanic got the scoot up on the lift.

No damage to the axle or surrounding bits.

All sorted.

As for towing costs, I just renewed my AMA membership.

The membership includes free towing for up to 30 miles.

It costs $145 for three years.

In the first three years I have had it, I had scooters towed at least five times and my Miata once.

These tows would have cost at least $100 each, so quite a savings.

Do you have a similar club in Israel?

Yes, that is a good one, but I have State Farm. They don't offer the same.

Pictures of a frat party could be very interesting indeed.
The aftermath, not so much.
