Basic intro to the V3 Cycle Analyst (CA3) Display Screens and Operation

This quick overview video demonstrates the basic use and interface of the Cycle Analyst 3.14. It is not intended as a full setup guide but covers how to navigate the display screens, operate the controls, and change simple settings. The demo unit includes a throttle, pedal assist sensor, motor, battery, and an on/off (MF) switch, all connected to a fully functional Cycle Analyst.

When powered on, either via the MF switch or directly through the battery, the device boots up showing the firmware version. The home screen then displays key metrics like battery voltage, distance, speed, power, and two status icons. The left icon is a throttle indicator bar that moves based on throttle input, while the right one shows pedal assist activity (e.g., human watts and RPM if a torque sensor is present). Activating the e-brake changes the throttle indicator to show a brake lever icon.

Cycling through the screens reveals additional information. The next screen shows electrical stats such as voltage, power, current, and amp hours. Following that is the human power screen, which also displays pedal RPM when cranked. There’s a watt-hour screen for total energy used and watt-hours per kilometer, which is a good efficiency measure. For example, a typical e-bike might use 10 Wh/km, whereas a more conservative rider could use as low as 2–3 Wh/km.

The human watt-hour screen tracks torque sensor data, RPM, and effort averages. The regen screen, applicable only to direct-drive motors, tracks energy recovered during braking and provides a percentage estimate of range extension. The max stats screen shows peak current, peak regen, and minimum battery voltage during the ride. There's also a ride summary page with top speed, average speed, and total ride time.

If a motor temperature sensor is connected, its screen will display live, average, and peak temperatures. The trip distance screen includes both trip and total kilometers; the trip resets manually while the total logs overall use. Battery statistics like internal resistance, cycle count, and total kWh used are also recorded. Finally, the diagnostic screen offers throttle in/out levels and limit indicators (e.g., voltage, current, speed). For example, throttle input and motor output levels are reflected in real-time. This screen is especially useful for troubleshooting.

To enter the setup menu, press and hold the left button. A bar on the left indicates pressing it again will exit the menu, while a right arrow means more options are available. To change battery voltage settings, scroll to "Setup Battery," press and hold the right button, then scroll to "String #." Press again to edit, change from 10 (36V) to 14 (52V) by adjusting digits individually, and save by holding the right button. To exit, press and hold the left button. You can revisit settings any time to revert back or fine-tune as needed.

Trip resets are done by holding the right button until prompted. Confirm to clear the trip stats. The MF switch also powers the system on and off while conserving energy. It includes up/down buttons that can adjust parameters like total power, and an "M" button to cycle screens. Holding the "M" button also resets the trip—ideal for in-ride adjustments without removing your hands from the controls.
