Dear ________________
Our records indicate that two years ago you purchased a bicycle for your son, _________________________ (name of child) for his birthday which falls on __________ (date)
If he is ready for a larger bicycle, you may wish to surprise him on his upcoming birthday with one of the beautiful models we presently have available in our shop which would be suitable for a young man of his age.
We do offer a modest trade-in allowance and, of course, will be happy to deliver the bicycle to your home in order to keep it “under wraps” until that special day.
Give it a thought and if you feel that ___________________ (name of son) would be pleased, come in to visit us at your convenience and I will show you our stock.
