As the title suggests, this is what I'm planning on doing. There is no way I can afford one otherwise. My employer doesn't do any kind of cycle to work scheme, and I don't want to buy on credit. I have bought all my other bikes second hand, no problem. However the electric element of e-bikes dose make me a bit nervous. The primary reason for buying one will be for commuting to work, but Id be kidding myself if I said I wouldn't be taking it up my local hill (or everywhere else). So second hand buying advice please, replacement costs for motors etc because I doubt I will get any warranty support. My budget is about £2500/28000.
