Which type of bike for me?

[NbyNW]

5 miles, 30 minutes = 6 minute mile, = 10 mph. HIlls... any traffic lights are issues (stopping wreaks havoc with time ) but it should be much more do-able on any road bike vs. mountain. My folding bike is much faster than my slower bikes, too, and I can tuck it under my desk .

I also commute on a folder. It's an agile, versatile little thing, and my 5.5 mile commute takes about 30 minutes in the morning (mostly downhill, with traffic stops) and 40-45 minutes in the evening (mostly uphill). Mine is a one-size-fits-most (Dahon), but you can get them custom, too. (Any Bike Friday owners want to chime in?)

A folder is a nice option if you don't feel comfortable locking your bike to a rack outside for 8-9 hours at a time. I feel pretty safe keeping mine under my desk, as we don't have tons of unknown people roaming through.

If your office provides a secure place for storage, well then, never mind.
