Well, as far as I know, Inquisitor Lords can't be mounted on Bikes, which makes the tactic a lot less viable.
For real powergaming, just take 2 Librarians on bikes, both with FotD, and then "escort" your opponent units that are falling back, until they run off the table (units can't regroup if there is an enemy unit 6" or closer to them).
For an effective Biker army, I'd just go with Bike Squads as Troops and Elites, mounted HQs and Land Speeder Tornados w. Assault Cannons for Fast Attack. 2k points isn't that much, you'll have like 30-40 models depending on the build, and you don't want your precious Predators/Land Raiders stuck on their own in the rear as the rest of your army zooms up to engage the enemy and claim Invulnerable Saves.
There are quite a few threads started around here on Biker armies recently, have a good read around the boards before you try and write a list.
