Hi:
I have been an avid cyclist for many years and since I was diagnoised with Parkinson's Disease 4 years ago, cycling has become a vital part of my exercise therapy to delay the effects of the disease. However, I no longer have good enough balance to ride a regular bicycle and so I need to get a recumbent tricycle, but they are very expensive. I have the following questions.

Does anyone have any experience with getting their medical insurance to pay for this type of equipment?

Does anyone have a used recumbent trike for sale (tadpole style)?

Are there any foundations which pay for this type of equipoment?

Has anyone built their own recumbent trike?

Thanks for any information.
