It is quite well known by parents that children with ASD often experience difficulties learning to ride a bike although the NAS doesn't seem to notice it, or that approximately half of all children with ASD are unable to ride a bike by their 10th birthday.
Can your ASD children ride a two-wheel bike? Did they find it easy or did they struggle learning to ride over a prolonged period? Did they learn to ride using a balance bike or with stabiliser wheels? Did any children start off on a bike with stabilisers and failed to learn how to ride without them, but learned to ride using a balance bike at an older age? Have any children had professional training how to ride a bike or training by a local ASD support group? Have any children been trained at school how to ride a bike?
