I didn't have any luck finding my 240V inverter, but I was able to borrow one from a friend (in exchange for fitting it with an Anderson Powerpole connector.)
So, you have a peddle powered generator.. what's the first application or device that can be tested with his new power source? Being Australian and and an Amateur Radio operator, the first device had to be a radio. (For overseas readers, Australia has a proud history of peddle powered radios, which together with the Flying Doctor service, brought emergency healthcare to the centre of Australia.)
The second application was therefor a peddle powered television.
The small television did not have a rating listed on it anywhere, but after peddling for 30 minues or so, while catching up on the evening news, I would say that it is about 25 or 30W. It is uncertain what the efficiency of the inverter is at this stage.
I see this setup quickly becoming a core part of my exercise program.
