Trying to find a good ebike for my wife, but finding it difficult to find anything reasonably priced that will work for her size. She is 5'1" but finds most bikes rated for this height to still be too big. Perhaps she has a shorter inseam than average for this height I don't know. The second issue is she has had a multiple back surgeries, so she needs something along the lines of a comfort bike, preferably with a low center of gravity. So far the best options we have seen are the 24" Pedago Comfort cruiser, which no one seems to have in stock, The Electric Bike Company model M, which has the basket mounted battery which I assume means a high center of gravity, or the Blix Sol. Any other good options in the sub $2500 range?
