You may not be able to pull open the locking bolt (to open the Van 'n Bike) on the left side when the bikes are loaded.
By pushing lightly on the top left of the Van 'n Bike you will be able to pull the locking bolt open.
This is because when loaded, the Van 'n Bike will tilt slightly at the top, causing the pin of the locking bolt to hit the wall of the recess, making it harder to open.
By pushing against the top left of the Van 'n Bike, this pin is released and you can easily pull the locking bolt open.
It is also recommended that while tightening or loosening the crank handle, push against the Van 'n Bike at the top left.
This places less stress on the "teeth" in the crank handle and significantly reduces the likelihood of damage to these "teeth.
