is this the same rule or if you include both a chapter master and a captain, can you have two units of bikes count as troops, or just one?

most people would just take white scars and choose Khan so its not an issue, but its still an interesting question as even khan has the mounted assault special rule, but its worded differently too.

The rule doesn't specify anything about only being able to take one unit per guy, either one lets you take as many bike squads as troops as you want.

As long as you have five dudes in the squad your golden.

You don't have to include both, even. Just one will do you. Neither says "A bike squad of at least five models" , the wording is "Bike Squads of at least five models may be taken as troops".

The first wording, which would require multiple HQs to take multiple bike troops, refers to a Bike Squad in the singular. That isn't the wording in the Codex, however. The wording that is in the Codex, the second entry, refers to Bike Squads in the plural.

... and then I go back and review the post to see that miv beat me to the punch.

Hey, its all good.

The only question then is if Khan is worth taking for scout or just taking a just a tooled up customized Captain.

Well someone has already pointed out Khan+Dev Centurions+Dedicated LR = Profit. Threat range goes from 30" to 48" on the first turn (12" scout move + 6" move + 6" disembark + 24" range).

Keeping Mounted Assault in mind I came up with a quick little 450 pt allied detachment of Marines for Tau lists.  It provides some nice assault and melta pressure from the first turn on, letting the Tau blow everything else up with Missiles and Plasma
 
The list:
 
Ravenguard Captain (145 pts)

• Bike
  Teeth of Terra
  Iron Halo
  
  

5 Marine Bikes (140 pts)

• 2 Graviton Guns
  Sgt with Melta-bombs
  
  

3 Multi-melta Attack Bikes (165 pts)

Devastator marines + droppod + devastator doctrine

10 man sniper scouts+aegis line+ telion+ml w/ skyfire. Mook shoots the quadgun, telion shoots the missile.

hap master w/ artificier armor, boss shield and flame sword.

I thought Devestator doctrine doesn't work when disembarking from a vehicle.  Would be WAY to good if it did.

Relics are 1 per army as well.

Doh, you are correct on dev doctrine. I has a sad.

Relics are limited to one each per army tho.
