Would expect 30 sec peak power above 1.000 watts. This is at least what is seen by pro cyclist and speedskaters.

Btw interesting discussion on Slowtwitch (triathlon forum) about the BikeErg http://forum.slowtwitch.com/forum/?post ... 98922#last

Specially jow the power is calculated on the bikeerg vs rower

"The trouble is C2 can't use the same logic to calculate power for a bike as they can for a rowing ergo. For a rowing ergo you can use the recovery phase and the deceleration of the flywheel to effectively calculate the air density. But for a cycling erg then you don't have that phase where you know no power is being applied".
