Looking for a 125 starter bike

I’ve just done my CBT, so need a 125 for a few month/ years at least to practice on.

If any one has a nice old bike they’re getting rid of I could be interested in looking after it.

I’m in Wimbledon, but do have an Oyster Card at my disposal.

Instead of “rid of” I typed “ride off”! Freudian or whaaa?

Cheers
