Cannondale make a nice bike but they are also a bit of a thief magnet.
The Bad Boy series sometimes suffer from issues of rack/fender eyelet position.
The Bad Boy eccentric bottom bracket is known for creakiness.
The one-piece bar/stem lacks the adjustability of normal units

I ride a hub-geared Alfine bike with dynamo front hub as a grab and go bike. I prefer this to derailleur and battery light systems. I would fit a clean belt drive if I could.
