I am looking for ideas for an ebike for my wife. She will shortly have a replacement hip operation and I am looking at an ebike as a recovery aid. I want her to be able to ride out with me...no tarmac....fire roads bridleways and mellow single track only so no "real" mtb! She will not be able to manage standard mtb frame design so a step through is needed. I want decent components and xc type wheels and tyres. Hardtail would suffice. Anyone gone down this route that can advise?
