Tulip, how long does it take you to ride 10 miles on your Bike Friday?
Same time it takes me to ride it on my Luna. I average about 14-15 mph, with cruising in the 17-18 mph range. Depends on the terrain, of course. Last month I rode about 300 miles in the Arizona mountains in a week on the Friday, and last week I rode 200 miles on it at Cycle Zydeco (4 days). I'm doing two centuries on it in May. It feels like a full-sized bike and rides like a full-sized bike.
