The reason (i'm sure you're all wondering) is that in this episode there is a push bike with a motorbike sidecar bolted to it. My mates claim to fame is that he designed an built said bike and sidecar for the telly program when he worked at a bike shop. The thing is he's never seen the episode with it in, so I said I'll try and find a copy for him. I've found one torrent which has no seeders, so thought that uknova might have it. unfortunately it doesn't
I'll have to keep an eye on UK Gold, but as they've started showing it from series 1 starting tomorrow, it might take some time to get to series 25.
