How do i calculate my wattage output on a bicycle?

Answer 1

as far as i know either a trainer equipped with a measure or one that hooks to your rear wheel is the only way.  it isnt like a calculation you can do, as far as i know.  the riders on the tour have a special hub that measures thier output.

Answer 2

The best way is to use a power meter.  They have wireless meters now that you hook into your rear wheel, and then the display is attached to your handlebars.  Also, if you have a trainer, that would be the best test for it.

Answer 3

get a power meter

Answer 4

As everyone say, a powermeter will solve your problem.

If you or know someone has a computrainer, you can hook your bike on it and ride it and find out your wattage output.
