Women's Schwinn Merano 16" hybrid bike

This bike has been ridden fewer than a dozen times and is in superb condition. It's frame size is best for a person 5'-3" to 5'-7" tall. The hybrid tires are suitable for riding on asphalt or gravel roads and on smooth dirt trails. The aluminum frame makes it light and easy to handle; the front shocks give a comfortable ride on bumpy roads. The bike has Shimano v-brakes and a 24 speed Shimano EZ Fire gear system. Included accessories: a rear carrier; a heavy-duty Bell U lock; a gel seat cover (total added value is $80)
It is almost identical to the Schwinn GTX-2 Women's Hybrid bike currently selling at Canadian Tire for $549. Why buy a new one like that when you can get a beautiful Merano model for less than half the price?
