setting rider weight

[wellmt]

In the device->other settings menu option you can get/set the bike weight and rider weight. I assume that this rider weight is how the Watts per KG/Fitness score is calculated from.

Should the rider weight be fully geared up weight, or just body weight? I'm sure I read that this should be full gear weight..but I might have imagined it.

Thanks

For the weight screen in the setup you want to enter your weight+clothes+bike. This will be used for calculating power.

When you enter the screen for the fitness test you will see a place to enter your weight. This is where you enter JUST your body weight. Then based on your 20 minute power you will get the w/kg reading.

Ah! Thank you for clearing that up.

Most other power meters calculate W/kg using only the rider weight, not including the bike, clothes, water, etc... Does this mean that the iBike-calculated W/kg is always going to be lower than what's calculated by other devices? Or is the total weight important for the real-time processing of data, but then the final W/kg is automatically adjusted so we can do an apples-to-apples comparison with folks using a Power Tap?

Nope, the w/kg will be based on body weight only.

For all power processing equations, the iBikes uses you+clothes+bike weight.

Example, if you ride at 300 watts and your body weight is 75kilograms, you will get a w/kg of 4.0

If your bike plus clothing is 10kilograms, then all power numbers will be based on a total weight of 85 kilograms.

Note that there are a couple of places in the iBike setup screens to enter weight. One is the rider weight in the fitness screen (for w/kg) and in the fast start screen which helps establish CdA. Then as part of the regular setup screens you can enter your total weight on any given day depending on your bottles, clothing, your weight, etc. I think I got that correct.
