Think to remember is that ebay is full of idiots, some honest, some dishonest, and it is difficult to spot the honest buyers. However it is difficult to argue with the size of the audience the item receives.
I recently sold a bike on there with a minimum bid of £1000 (twice what someone on here would tell you it was worth). I had dozens of requests to sell it for cash before the sale ended (between £750 and £1300). I just told people to bid if there were interested and that I would not be supplying my address for collection until the payment was made and received after auction had ended (I do this for all items). Eventually got £1150, and was happy with that, as was the buyer.
You don’t need the hassle of meeting people to view, and unfortunately there are too many time wasters/crooks on ebay to allow that. Describe the bike accurately, and take lots of photos so you can prove the bike is as described, and has been collected by the buyer. If that diminishes the market, tough.
