Jet Bikes!

[SotonShades]

eagle for me, but both look fantastic. can't wait to see how the rest of the bikes turn out

More updates today. I've been able to flesh out more of the middle and rear sections and it's really starting to take shape. Once I figure out how I want ther rear section to look I'll be able to move onto the engines.

Which brings up the next question: What should I name these things? (i.e something non-WH40K specific)

[Grailkeeper]

Jetbike isn't necessarily very 40k specific but you could try Hoverbike or Jetcycle.

[Meph]

Indeed.
And I would stay away from names such as Steel Hover Pony and such...

[Machinator]

I don't know, Hover Steel Death Pony does have a nice ring to it

Nah, I'm look for more descriptive terms like Sky Shark or Falcon.

[Meph]

How about Peregrine? Or Garuda, half man & half eagle, the riding beast of Vishnu.

There we go! Those are the kind of names I'm looking for

[Drew da Destroya]

I'd second Peregrine... falcons are badass.

Mako could also work, if you want Shark-themed.

[Meph]

The more I let it roll around in my head, the more Garuda sounds appropriate. peregrine is a wicked name as well, but somehow it conjures up an image more like a fighter or attack craft. the name of a mythical riding beast suits a jetbike quite nicely.

other mythical riding beasts:
Krute: Indonesian half-bird, akin to Garuda
Hercinia: a bird with glowing feathers from Medieval bestiaries.
Pegasus
Wyvern
...

Some interpretations of Garuda:

I like Mako for the shark one. Garuda and peregrine sounds good too.

A name suggested on another site for the eagle version was the Talon Assault Speeder.
