Narrative:

Pre departure clearance altitude was 7;000 feet as usual for the mountain departure. Takeoff weight was 58;000 lbs. And normal thrust. Rain had just stopped so engine anti ice was no longer required. Another [company] crj took off in front of us. Climbing through about 1400 feet at +18 pitch and about 4000fpm; tower said 'maintain 2;000.' we were still at flaps 8 or 1; I can't remember. Leveling off required a pretty aggressive pitch down and I'm sure it alarmed at least some of the passengers. I overshot by about 200 feet but returned to 2;000 feet. About 5 seconds after leveling off we were told to resume climb to 7000 feet and contact departure. No explanation was given. The captain queried departure regarding the reason for the level off but he chuckled and said he had no idea. I'm submitting this report in hopes that word will get passed along to sea tower that these last-minute level offs are very difficult to comply with and uncomfortable for our passengers. I talked to another sea pilot who said the same thing has happened to him twice in the last week. I think it has to do with traffic separation; especially when we're light and climbing at a higher than normal rate. It was late at night and not incredibly busy; so I'm not sure why the tower controller couldn't just wait 10 seconds longer to clear us for takeoff.
