No, my commuter bike is my nice bike. I put about 140 miles per week on my commuter bike, and the ride includes a fair amount of rolling hills terrain. I have an enclosed bike locker at work, so I don't have to worry about theft or leaving the bike outside in the elements. So I get to use my nice bike for commuting, which is the majority of my weekly bike distance. My "errand bike" which is used for short trips near home is the closest thing I have to a "beater bike", but it gets light use and low mileage. My fair weather "weekend bike" is a 29 year old Ciocc which doesn't have fenders or a rack. I like to take it out for a 40+ mile leisure ride like I did today. After riding the heavier commuter bike during the week, the Ciocc feels a lot different, and is a bit quicker on the hills.
