I am not in the fifty plus crowd, but my Dad is. He is 67, and in fairly good shape. I have convinced him of the benefits of riding, and he has asked me to pick out a bike for him.
Are there any considerations for the bike appropriate for the age group? He will ride on trails and streets, presumably 10 miles or less. He wants both comfort and speed. I am tempted to pick out a hard tail MTB/hybrid, because that is what I know and love. What is your objective choice in the $500 range, new or used? thanks.
