Our tour guide Ashley was funny as hell. It was refreshing to go on a tour that didn't try to be too formal -- it's Amsterdam, after all! We peddled through the the city center (Red Light District included...that was an experience) and learned a few bits about the city as we rode. Mostly, we just had fun and laughed.
Rob and I immediately came back and unlocked the bikes that came with the apartment and went for a ride. We've been out a few times since and are kicking ourselves for not embracing the local mode of transportation earlier in our stay.
