Wyatt has autism and bipolar, anxiety, depression and developmental delays he was able to benefit from a balance bike last year and we are very happy to report he is ready to move on up. However with his autism I am uncomfortable sending him out alone. We have 6 kids all with different sorts of disabilities. I feel the tandum bike would be big aiding in fun and exercise. He is excited to get moving this year. Oh the adventures he will go on. Please help us make this possible. Many thanks.
