Yesterday I rode about 3-4 miles around our neighborhood and today rode  over 9 miles  on the trail de paris-met a gentleman riding by on his 2 wheel sun bent...it is obviously geared for speeds faster than mine...he slowed down a little to tell me about how far he rides (13 miles 3 to 4 times per week on the trail). I had seen him other times riding his bent and that unusual bike is kinda what got me interested.
