Anyone have a Davina McCall folding exercise bike?

[Slippermam]

Totally random but I’ve lost the locking pin to make the bike stay folded up. I’ve attached a pic of the bike and a close up of the locking pin in it.

If someone has one can you measure the length and the diameter of the pin please so I can try and find a suitable replacement please?

I have a slightly different version of this bike, my pin is roughly 11cm in length and 0.5 cm in diameter. hope this helps. I tried to post pic of my bike but not sure how to add it to the message
