one wheeled wobbling?

after a while of being on 1 wheel i start to get a bit of a wobble sometimes. a lefty righty one, not a choppy throttle one.
its fine on 2 wheels, no buckles or anything like that, so im pretty sure its something im doing wrong.

only happens at low speeds. about 10-20mph. above that its fine. it also only happens after about 10 seconds. not over-revving either. we're talking sat at about 1/4-1/2 revs.

ideas/theories im interested in. not someone who wants to look like they know.

maybe you're moving the handlebars slightly while the front wheel is still spinning and this is having a gyroscopic effect on the bike.

Try pulling the front brake when you're on 1 wheel and see if that makes a difference. Make sure you release it before you set the bike down though. Laughing

It's just a guess but I suppose it narrows it down a bit more.

I'd be thinking of other things that effect the rear wheel also such as alignment, wheel bearings etc.

As I said, this is just speculation. For all I know, maybe the wobble is normal.

An afterthought:

Maybe wind etc have less effect on the bike when riding at faster speeds, whereas at lower speeds the wind can make it wobble about. I guess the bike is probably more stable on 1 wheel riding at 50mph than at 10 or 20mph.

I can't wheelie myself, but this is my thoughts.

I suspect it could be where the old rusty bullet hole is puckering and twitching with excitement of getting it up and this is transferring to the rear wheel.

I don't know, just spit balling.

I thought the whole idea of getting on one wheel was to have a twitchty bum hole.

Stop complaining Laughing

the whole adrenaline from being on 1 wheel gets old pretty quickly.

hence the trying to learn slow speed stuff.

If you're having stability problems after being on 1 wheel for more than 10 seconds at 10-20mph then I'd say your speedo is broken and your ability to estimate time is also broken.

Don't slow down then, I should charge for this sort of advice.

Arse. OK, look up "torque-free precession".
