Am only 5" with short legs and weigh 50kg..My knee is acting up so looking at getting an electric bike for commuting to work, shopping etc. The problem is they all weigh 25kg and with panniers it'll be over 30kg. Any other petite riders out there and am I just being anxious worrying about the weight of the bike? I won't have to lift it anywhere,just concerned about control and responsiveness of a heavy bike , especially on a windy day . I can't rent one for a week as there aren't any small frame bikes for rent in my city
