With my son having Duchene Muscular Dystrophy/ Autism,my son has never had the joy of riding a bike due to him not being able to use his muscles in his legs without experiencing some discomfort and with his autism him not understanding that he has to stir,pedal the bike at the same time ,he'd be thrilled to be able to get a bike.
