That's 'cause most of them are American sites.
I'll get my bio cards and snap 'em.
EDIT: Here you go; bios from the UK release Axelerators.
Rapido:

Zap (alias Cheesecutter):

Hotrider (alias Turbofire):

Skram:

Looking at the figs again, Hotrider might work really well from an Alt Prime too; the G2 version's actually a pickup. But the Jeep's looking pretty tasty anyhow, and the robot mode looks much more like him than the Ram would've. Actually, considering how G2-accurate you're getting them so far, I'm thinking Skram would look wicked made from the Mazda mould. A Shockwave (with new head and hands, natch) should be a doddle to repaint.
I really want to pick up Cyb Dirt Boss to replicate my Skram digipaint...
