A drop down / drawn bridge ramp the width of the door way would be good, in the up position it could be bolt at the two top corners and used to add security to the doors. Also with the floor possibly needing more strength to cope with the weight of the bike, putting extra boards down could be used to raise the floor to match the door jib, this would remove the bump as you push the bike out.
