For those who say the 'wife couldn't do 50 miles on her own' are you refering to the distance on the bike or trying to ride 50 miles all by herself, solo, no one to talk to, no one to be there if some cager uses her for spitball practice?
I can ride 50 miles on my bike but there is no way I'd do it solo. I'm not a HUGE fan of biking in the first place. I enjoy it only when the hubby and I do it together. I'm having more fun now that we are riding TWOgether.
There is a difference between riding 50 miles on the bike and riding 50 miles SOLO on the bike.

So, which is it really?
