Echelon EX-4S

This is an exercise bike we bought today at Costco.

It has a one-year warranty on it and a one-year free trial for the Echelon service.

I have to get used to the idea of not breaking into it for a year.

I can make notes in the meantime, right?

It loads an app that takes over the screen and I'd like to use it for other things, like running an audio book from Hoopla for instance. For the next year I'll use my phone I guess. Sigh.

Anyway here are instructions on what to do,

Accessing the Android Settings

1. While you are in the Echelon app, click the bottom, right-hand corner of the screen 5-10 times.
2. If done correctly, you should see a pop-menu asking for Code.
3. Enter 1085 or 0000
4. If the Code is accepted, you should be in the Android Settings screen.

Next... follow these steps in (post #27) to start setting up your access. This task involves changing the Default Home app to something like Nova/ Lawnchair . 

Metrics

• Speed (totally fabricated)
• Cadence
• Power output (calculated from resistance and cadence)
• Resistance

There is a knob to adjust resistance but it's just an encoder apparently. It does nothing unless the CPU is in the loop, so I presume a message goes to the CPU when you turn the knob and that it sends back a command to move the magnets in and out.

Whenever an exercise video ends the bike goes back to level 1.

If I cannot read the sensors built into the bike I can always just more.
