For an Ultimate Commuter Bike, this one fits the bill pretty well. Its a 2012 Scott SUB 10 with urban kit. Here are some of the features that I appreciate so much as an urban commuter:

- 8-speed Alfine internal gear hub: An IGH is great: Not only is it maintainance-free, its also so easy to gear up and gear down at stoplights
- Gates CTC Belt drive: clean and maintenance-free, no grease to dirty up your pant legs
- Supernova dynohub and light kit (front and rear ligths) - beautiful!
- Shimano disc brakes, so much more predictable and responsive than rim brakes in busy traffic
- Urban kit includes integrated fenders, rack and kickstand

Some additions:

- Jandd Saddle Bag Pannier. I don't think the Scott rack will fit standard panniers. However, this Jandd saddlebag fits perfectly. Room for rolled-up office clothes on one side, and a 14" laptop and lunch on the other
- Schwalbe Marathon Plus 700x35 tires. I ride through an industrial area, and was picking up punctures from scrap on the way to work. Not the best way to start the morning. And yes, IGHs do complicate tire repair. These Schwalbe's solved that problem.
- Shimano PD-T400 Click'R SPD Pedals. Wonderful/highly recommended: they hold my shoes firmly; yet I can click in and out without effort or forethought. No more of those embarassing spills at stoplights.
