I bought a 2nd hand Ghost Teru eMTB via Jack / GC2012 of this parish last Christmas. It was supplied from Germany with a two year warranty on the major components, it uses a Bosch CX Gen 3 battery and motor. Cost was £1200 (about half RRP) it had 1940 km on the clock on arrival and now has just over 4000 km. Consumables have been tyres, chain, front sprocket, brake pads, ie. the usual but the motor is harder on chains, sprockets and rear tyres. The motor was a bit rattly to start but torquing up mounting bolts and sorting the upper battery mount fixed that. It has been used off road in the Peak district (read rocky and steep) and has been excellent, I wouldn't have ridden trails like Mam Tor, Edale Cross, Doctor's Gate etc. without the motor. It will do 35 miles of off road with climbing on one battery charge (over 40 miles on the flat and using eco mode). Reliability on the electrics has been good - I have been careful not to drown it in fords etc, but it hasn't been babied. I fitted a suspension seat post as the hard tail was giving my backside a pounding. All in all an excellent purchase that I am very happy with.
