Really the only big change I made was I went to recumbents in 2005, and have been bent ever since. The comfort and view was in instant reward for me. As far as distance and speed, it still is about the same. I will be 84 this year and ride any where from 20 to 35 miles every other day, weather permitting. I have both a LWB bent, and a tadpole trike. I ride the trike mostly in town, and the bike out of town with the bike club.
