I have an electric bike - it was adapted using a Swytch kit (see earlier posts). The kit was very easy to fit. lietoswim, can't understand why bike shops won't fit these for you, but it was pretty easy to do yourself. I've found it great, only drawback is they are heavier than before, but not too hard to carry upstairs at my local station. The front wheel drive, Malumbu hasn't been an issue at all. Also plenty of range, have never got down below 3 levels out of 5 on the battery level indicator. But haven't cycled long distances with it, max 26 miles maybe.
