How much memory does the PowerTap computer have available?
The PowerTap computer has a setting that lets you change the data collection rate. When you set up the PowerTap computer (press MODE and SELECT buttons simultaneously until you see SETUP) you can select data collection for every one-second or every two-seconds. If you select “one-second” the PowerTap will record up to 7.5 hours of data. If you select “two-seconds” you will record up to 15 hours of data.
