At 250 watts that had better be a mid drive motor that uses the bike's gearing. A hub motor or even a separate EZIP-type drive wouldn't be much good on hills with that output...

The photo appears to show mid-drive, and I found a press release which says:
A high level of ride comfort is made possible thanks to the 250-watt centrally-mounted motor.

There is also the lesser-known fact that motors rated for the EU at 250 watts will often have a 500 watt (or even higher) maximum rating for short bursts.
