History of recumbent bikes
The question is this: when will you give one a try? The surprise to many is that recumbent bikes are NOT just for old people, or the handicapped, or anything like that. They are just another bike - and one that will likely allow you to be faster and WAY more comfortable than your "safety bike" frame. Period. Anyone who argues this has simply not tried one.
And for those out there who are "reaching the age" where riding your DF is just getting too difficult - for your neck, ass, balls, wrists, back, shoulders, or whatever - what are you willing to do? Try a recumbent? Give up cycling forever? All of us who ride will face these questions eventually.
