Girls bicycle (IP2)

Hello, my grandaughter would live a rideable bike of her own for christmas. If anyone has one to spare that would suit a 12 year old height that needs little or no work...please do not hesitate to contact me. My grandaughter is 9 and has only just learned to ride her friends bile recently. I am asking for a bike suitable for a 12 year old because despite her age she is just shy of five feet in height! Many thanks for taking the time to read this.
