The 11-year-old had a sore hand the rest of the day but it was not until the next morning when his hand had swollen up that he and his family realised he had broken a bone.
His cast was removed this week following the accident last month.
"My hand was all swollen up," Maikyren said.
"You can still see some of the bruising. My hand is still a bit green on top."
His little finger was bent sideways into his palm, he said.
"It was snapped out of place and dislocated and bent inwards. But I wanted to go back to school straight away."
Maikyren said he did not bike to school anymore.
"I don't feel safe. And I can't get a proper grip on my handle bars.
"I just run to school now."
Te Puna School principal Neil Towersey said people needed to be careful when entering or leaving driveways and being conscious that between 8.30am and 9am and from 2.50pm onwards, there were childrenon bikes and they should be more alert.
"People need to be super vigilant of the fact there are children out and about on bikes or on footpaths."
Maikyren's grandmother, Annie Rose, said she thought someone would have come forward or at least contacted the school to see if Maikyren was all right.
"I think to myself, this is a child.
"They should have at lest come and asked how the child was that was hit."
He had been wearing Te Puna School uniform items so it would have been obvious which school he attended, Ms Rose said.
"It's not just my kids that walk or bike to school.
"It was on a straight bit of road, there's nothing obstructing the view," she said.
"No one has come froward to say they saw it either.
"We could have been burying him."
