I know guys that have quarter acre lots and insist on having a huge riding lawn mower to cut their grass. I like my $200 Sears push mower for my one acre lot. It takes me two hours to cut the grass, but I move swiftly and I get a workout.
There are always a few people out there trying to impress others with their toys. My philosophy is KISS (keep it simple stupid).
My Bike is a 15 year old steel frame TREK 400 purchased at a yard sale for $35. Of course it took a few bucks updating the bike, but it was a lot cheaper than paying $2500 for a new lightweight bike. I can average 18-9 mph on flat terrain. Perhaps I could do 23 mph with a new lightweight model, but I am out there for a workout and not trying to impress others.
Good for you for recycling cycling! I still have my ancient road bike, I bought it in 1973 so of course it's a heavy steel monster. It was a really good bike THEN, though. My son is really into mountain biking so he helped me rebuild it recently and it's good to go. We go out occasionally for a family jaunt and it's good enough for me!
