If you get a Downtube, keep in mind that you will have to take it to a shop and get it tuned up. This is required with any bike, but if you purchase your wheels in an LBS they usually throw in at least an initial tune-up, if not 1 year of service (within reason).

The 1-speed Boardwalk usually runs around $200 and ought to do the trick if all you want to do is ride on flats. If you spring for a Dahon Speed D7, or a Downtube + tune-up, you'll have a much more versatile bike.

Don't forget to budget for the extras:
• front and rear lights
• gloves
• helmet
• a good bag to put on the rear rack
