Isn't this cool? After seeing Sam love the hand crank ride at Knoebels, I was determined to find him some type of adaptive bike. We found this very cool and relatively inexpensive ($69.99 on Amazon) compared to "real" specialty bikes (thousands of dollars!). He wants to do whatever the other kids are doing and he is determined to learn a way. I love his persistence and that he doesn't become frustrated or quit. He is such a great role model. He is going to achieve great things!
