I have a Cannondale 50/50 nexus 8 internal hub designated city/commuter bike. They work well but if the commute is a longer one, I found the bike to be uncomfortable, even with a stem riser and various types of hanlde bars. My commute is 30 mi. + round trip. If the commute is shorter, say 10 miles each way, I think a bike of this type works great. I just used the Cannondale yesterday for 20 mi ride towing my son and his trailer bike and it worked great! I am a big fan of the internal hubs in general and feel that (Nexus, Rolhoff, Sturmey Archer, (Old or New) help inrease my enjoyment of cycling. Easy to use, easy to maintain great for all around cycling.

Cannondale it seems,does not want or can't sell commuting bikes in the US. I bought the above mentioned bike and had a very difficult time getting it (had to drive from Philadelphia to NYC ) and now the bike has been dropped by Cannondale in less than two years.
