For the final C-chest we've selected From sale of stock you get £50.
I've never managed to sell any of my bikes, through eBay or any other channel, because they've ended up nicked, lost, abandoned in a college cellar, or run over by a builder's lorry while parked.
But eBay looks a pretty good way of turning an unused bike into cash. Because I've never seen a half-decent one go for less than it's worth. You think, aha, there's a Dawes Galaxy that must be worth five hundred quid, and it's only been bid two: I'll keep an eye on this... but in the final minute of bids, it ends up going for six hundred and fifty.
Conversely, I don't think eBay is a good place to pick up a bargain bike, especially if you don't get the chance to inspect it and try it first.
But then, where is a good place to pick a decent second-hand bike at a sensible price? All the shops I've seen in London that do used bikes don't do them as bargains. Getting a quality tourer second-hand is something I've been trying to do for years without success. So if you have one to sell, let me know, and for your sale of stock you'll get considerably more than £50...
