Wanted: second hand bike, where is best to source one?

[Jamma]

My son needs a new bike, ideally a 26 inch kids bike or a small adult bike. Keen to save the planet and get a second hand one if possible, but obviously in good nick.

Would love to get one off the forum if anyone has one to offer.

But also wonder if there's a good shop or lock up or something where we can source a second hand bike? Recommendations gratefully received. Thanks.
