Two main design goals: allow for easy freewheel removal with a simple hand tool to remove the lockring, and 2) place the drive-side bearing as far outboard as possible, to reduce axle failure.

Modern freehubs accomplish both these goals better than the Helicomatic, largely because a freehub incorporates the ratchet mechanism into the hub, rather than with the sprockets. This allows for larger balls than the Helicomatic design uses, which in turn prevents the wear issues in the rear hub that led to its poor reputation.
