Electric bike wanted. 5'6" and heavy-ish, wanting something mainly for Sheffield's hilly terrain, eventually with mudguards and a sturdy carrier. Also important that the electrics are fairly rain-proof, and don't look easy or useful to thieve from the bike, as it will be used for shopping, etc, so will sometimes be left outside (well locked up). A bonus would be using the bike for long outings and off-road paths. Thanks for any leads or suggestions.
