Look for a Georgena Terry Symmetry that has a smaller front wheel and low standover. Similar bikes were made by Shogun, Bridgestone, and Fuji?
Trek among others made small frame road bikes down to about 48 cm. Might also check out mixte frames.
I recently picked up a similar St. Tropez 28" standover height.
St Tropez Terry knockoff
Terry Symmetry or Trey?
