It may not be ugly, but I wouldn't want one. You want the weight as low down as possible. The heaviest thing is the battery, so at a minimum you want that mounted near the peddle crank. The next heaviest thing is the motor. Modern setups make the motor drive the pedal crank. Beauty does not mean functional. cf: high heeled shoes.
