Speed - Accuracy

Chuck said:

Having installed my Garmin Etrex GPS on my trike; I'm wondering just how
accurate it will be when used as a speedometer.

Anybody know?

Probably not as accurate as a well-calibrated, wired bicycle computer,
but probably good enough. I would think the usual GPS issues apply,
e.g. if you're riding in areas that may have signal integrity issues,
like an urban area with lots of tall buildings or a forested and/or
mountainous area, you could get spotty results whereas a wired bicycle
computer works well regardless.

Agreed. And nice point about being a wired computer. My wireless ascent
sometimes shows insane information. Like a ride on Saturday show max
speed of 75 mph! I only wish.
