Scimitar Jetbikes Counts as

[Valkyrion]

if I wish to use my scimitar jetbike models in 40k, do I run them as attack bikes or land speeders, IYO? 

Or is there another option?

[Noserenda]

Either of those could work on the right bases, though not both at once ofc :D

Could you use them as Outriders?

I thought they would make great attack bikes or ATVs, just give the rider a combi-auto bolt rifle or twin bolter. Edited March 16, 2022 by CCE1981

I think Landspeeders suit them best, the weapons are right, and they are fairly chunky for bikes.

I magnetised the weapon mount on one, made a twin boltgun, and run it as a Bike for a Librarian. It's only just bigger than a Firstborn Bike and about right for the Primaris ones.

It could pass as an Attack Bike with the main armament, but not as a Land Speeder as they are too small (unless you lash two together which is basically what a Javelin Assault Speeder is)

I've run them as attack bikes without complaint.

 

Different silhouette, but all dimensions have pros and cons to both players; the attack bike is wider but on the ground, the jet bike is longer but higher up.
