looking to convert my old Nicolai to ebike as a spare that will be used occasionally probably when Levo is out of commission. Wouldn't be doing anything hairy scary on it but looking for maximum couple of hours riding any recommendations. I was selling the bike but 2014 model top spec I can't ask and winna get what it is or was worth . Can you point me in any direction or recommend any one who can help. I don't fancy anything too complicated if you know what i mean.
