I've got some magnets I could use to swap out characters on a base, so I have some flexibility there. How often do people field two squads of all bikes (without attack bikes)? Would the bases look empty with only two models on a base?
Most Bikes around here are based two to a base, then a five unit formation equals ten Marines on Bike for a full squad, with an Attack Bike "remounting" two of those Bikers when added in.
The "emptiness" of the base is dependent on the size of the base, so you've got some control there.
One of the local Marine players uses multiple, 2-4, Bike Detachements in some of his armies to quite good effect; he very rarely adds Attack Bikes, using the formations purely as assault/support elements, often delivered via Thunderhawk.
I'd make a single "three-bike" base to put the characters in, per formation, and do the rest as two-bike bases... that way it sticks to the actual Codex Astartes squad size.
