Assembly
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this document
including all text under subheadings therein before set up or use of this product.
NOTE: Refer to assembly diagram on
facing page during assembly.
1. Slide the Hitch End of the Hitch Bracket (1) into
the vehicle’s trailer hitch and lock with a Bolt (7), a
Spring Washer (8), a Washer (9), and a Split Pin (10).
2. Install the Support Column (2) to the upright part of
the Hitch Bracket (1) and secure with a Bolt (5) and
Lock Nut (6) through the bottom hole and the Hitch
Pin (4) through the upper hole. When the back hatch
or tailgate has to be accessed, empty the Rack, pull
the Hitch Pin (4) out and swing the Rack downward,
pivoting at the bolt directly below the Hitch Pin (4).
3. Hold the two Carry Arm (3) sections over

Operation
Note: This rack is designed to hold up to
two non-motorized bikes only. Do not carry
flammable material on the bike rack.
1. Make sure that the Clamps are facing upwards.
Open the straps and place the bicycle’s top tube
onto the Clamps. Close the straps over the bike,
pressing the straps together for a secure hold.
2. Place the second bike facing in the opposite
direction and secure it as done in Step 1.
IMPORTANT: Make sure the front of bike(s),
when mounted, are at or above the bottom of
the bumper to avoid damage to bike(s).
3. The Clamps keep the bike(s) in position, preventing
them from sliding back and forth, causing damage.
The straps keep the bikes from bumping out of the
Clamps. For added security, use a locking chain.
4. Make sure bicycles are securely strapped down
before operating the vehicle. During long trips,
check straps and bike positioning, especially if
traveling on rough terrain. Approved strap tie-
downs are also recommended to support the
bikes for greater stability during transport.
Note: If you plan to carry only one bike, place
it in the position closest to the vehicle.
Note: When the back hatch or tailgate has to
be accessed, pull the Hitch Pin (4) out and
swing the rack downward, pivoting at the
Bolt (5) directly below the Hitch Pin (4).
