"He was just seen as being naughty for pushing or hitting as he didn't have the social skills to be able to say how he was feeling."
The family moved to a smaller town where they found a perfect school for their son and he settled in easily.
"His new school follows the Walker Learning Approach and he adjusted so well."
Seeing the difference this made to her son encouraged Ms Blythe to do something to raise awareness.
After seeking advice from a man who organised a similar charity event, she created Riding for Autism Awareness.
"Then I thought what would I do with the money raised?" Ms Blythe says.
"What better way to spend it than to use it to help educate our child educators, as it is not a part of their core teacher training."
The goal is to raise enough funds to donate to Altogether Autism who will hold workshops in the Manawatu, open to all child educators.
"Every teacher deserves the right training, and every autistic child needs a teacher to understand them to help them succeed at school."
Motorcycles and cars are welcome to join the ride leaving from Gary Worsley Motorcycles in Feilding and ending at The Wines in Himatangi.
If you can't make the ride you can still join the family-friendly afternoon from 2pm at The Wines. A speaker from Altogether Autism will be there to speak about autism and there will be a live band, sausage sizzle and face painting.
Registration opens 9am, Sunday, March 4, Gary Worsley Motorcycles, 38 Weld St, Feilding. Registration is $20.
