At last I put the bicycle together and rode it back and forth from work. I have not had a bicycle with good gears except for a few hours once, decades ago, before it was stolen and I can now say that bicycles with good gears are an entirely superior experience.
It is stressful to ride bicycles in traffic in the morning but coming home after rush hour, without traffic, the bicycle is infinitely more refreshing than the car. Infinitely.
Of course I now want this bike rack-mounting office bag, so it is good that I have not acquired the other accessories I also want.
