mUnicycle - 24 inch with Creepy Crawler tyre

I have a mountain unicycle bought from a few years ago and rarely used (mainly because I live in the flat Fenlands!).

Located in Cambridge, UK.

Very good condition, open to offers!

I’d prefer pick up in person, but willing to negotiate postage.

The creepy crawler tyre is 19" or 20" only, or am I wrong?
Anyway, I interested in a 24" muni, but i’m in Sydney Australia so it mightn’t be so good for me to buy it off you.

Sorry yes I mean 20 inch!

What brand is it ?
