I have a neighbor. 71 yrs old, pretty active, a bit overweight, and some rather serious permanent injuries to deal with.
His doctor told him he should ride bicycles. He wants to but finds it too painful. My short diagnosis of the problem is that he is looking at crap (dept store type) bikes and needs to be fitted for his physical condition.
He trusts me and knows what I spend on bikes. He wants to buy one of mine or have me pick one for him. However, I am skinny, flexible, significantly younger than him, and don't have the issues with injuries he has. Any of my bikes would put him in extreme pain. He has plenty of money, but I don't know how to fit him on a decent bike, and he won't trust anyone in a shop. What should I do?
