Hi Curley,
from Co.Down myself, needed something to cope with the hilly terrain and rough back roads we have,
bought frame and front wheel (rest i trashed) on the local gumtree for £25, added all new parts after that plus the Bafang BBS02 750watt kit with battery, now in the process in doing away with the rear derailleur and fitting a geared Alfine 8 hub... you could say it`s become a hybrid bike now, copes with much everything.
only thing i`d say is don`t skimp on the battery, get at least 13aH and upwards
bike weighs in now at approx 23kgs and cost of the conversion kit plus the battery was around the £600 mark.
If you live in hilly parts, not as fit as you were, have injury etc then this is for you!
