First - 97 and still riding! That is great, I hope I will still be riding (trike or not) at that age.

Second - Based on what I have seen my last 2 summers at the bike shop, if you do buy the Wal*Mart bike for her, please take it to a bike shop and have them look it over to make sure it is assembled correctly & every thing is properly tightened. (I don't have a problem with shopping at WM, I just was there this afternoon, but I have seen big box store bikes assembled in dangerous ways. They aim to assemble a bike quickly, not correctly.)
