Mr Wilson said he was surprised with the number of people who had read the column and supported the initiative.
Some Tauranga children would wake up on Christmas day with no gifts to open.
"This can be a year they can have a decent Christmas present that they will remember forever.
"It's nice to have the cans of food, foodbank parcels and putting the homeless up in motels. But this is something for the kids."
Mr Wilson said about eight per cent of pupils at Merivale Primary School suffered from homelessness.
"You add that together with the many families we are dealing with. Yesterday, a family of seven children had nowhere to sleep.
"Homelessness doesn't go away. It's not like 'oh wow, now it's Christmas now so nobody is homeless anymore'.
"It's always there. We see it every day of the year. So it's great for my staff to be able to sprinkle a little joy."
The bikes would be gifted to the children during the annual Santa Carrus Party on December 8.
"It's an experience they will remember for the rest of their lives. We might even have to get some more traffic control with a 100 new bikes for the Merivale and Greerton area."
Merivale Primary School principal Jan Tinetti said the bikes would be terrific.
"It's been a tough year for our children, this will mean so much for them.
"It takes the pressure off the family, too. Any family wants to do their best for their children and this helps them to achieve those goals."
