There are many organizations out there that donate transportation and/or equiptment that is used for PT. My niece recently got a bike esp. customed made for her leg length, and CP needs. Although, you do have to qualify for some of these organizations and if you don't, they do offer payment options. You just have to research for those groups in your area and even ask those people if they can't help you, if they know someone who can....if you don't care about buying the equipment outright, I believe there are parts you can buy to customize the equipment for safe PT. Good luck.
