Pros: Cool features like custom maps, drag and drop GPX loading, and pre-loaded topo maps. The rocker wheel rocks for text input and menu navigation. Bike mount (not included) is simple and very solid.

Cons: Would personally prefer an integrated rechargeable battery. Display needs backlight outside of direct sunglight. No TracBack capability.

Recommendation: This is a pretty versatile and rugged outdoor GPS. If you're only planning on biking with it, this may be overkill but it's great for hiking and other outdoor stuff.
