* For the quality improvement, design & parts are subject to change without prior notice.
** A 19mm(3/4″) Ratchet Wrench(or Spanner) is required for initial installation, and through the entire installation procedures, ‘Left’ & ‘Right’ are judged by the view from the BACK of the vehicle. And the vehicle demonstrated here is a ‘Left Side Drive use’.


A. Main-bar Installation

1. Loosen the eyebolts at both ends of the Main-bar evenly by 2-3” (50-75mm, Below left). Please note that the bolt & nut at ‘L’ side are left-handed screws, whereas those at ‘R’ side are right-handed screws.

2. Wide open the Quick links of both ends by loosening the nut screws. (Below right)

3. Connect the Quick links to the floor hooks & fasten the nut screws.(Below left) The ‘L’ side of the Main-bar should be placed at the ‘Left’ floor hook.

4. Pull & Rotate the Main-bar toward the back of the vehicle(“↓Fasten”) as shown above right, so that the Main-bar set is appropriately fastened. Do not rotate it too much as the floor hooks can be broken by excessive forces.

** Incase a karabiner substituted for a quick link, just hook it up. **

B.  Bracket Installation

1. Pull entirely out the left-most headrest from the 60% part of the 2nd row split-folding seat-back.

2. Place the Bracket onto the position where the headrest was placed. (Below left)

3. Re-install the headrest to its original position and make sure that the headrest supports went through the Bracket fixing bolts. (Below right)

4. Tighten softly the Bracket fixing nuts with a 19mm(3/4″) spanner. (Below left)

5. Fold down (Full-flat) the seat-back UNTIL it is securely locked. (Below right) Seat-back without locking mechanism needs to be locked manually for stability.

C.  Frame set Installation

1. Attach the Frame sets each to the Main-bar & Bracket by simply fastening 2 knobs as shown below.

Main-bar Frame Installing

2.  The Frame sets should face each other after installed. And the extended center line of one Wheel holder is recommended to pass by the center of the other Fork holder as shown below.

(Ford New-Explorer: The Frame sets should be attached in the same direction. It’s because the floor hooks are located inside around 17” away from the tailgate.)

Bicycle Loading:

A.  Remove the front wheels of the bicycles to be loaded and lower down the saddles to the lowest positions. (In some cases, the saddle has to completely be removed. So, mark or remember the original heights of the saddles.) And, remove the mirrors, if there is any, attached to the ends of the handlebars.

B.  Get the holders (Fork & Rear wheel holder) of the Frame sets ready. (Below left)

C.  Load one bicycle FORWARD (Front & Rear of the vehicle & bicycle are at the same direction.) onto the door side holder first. (Above right) Tightly fasten the Fork holder knobs & buckle up the wheel strap as shown below.

** Bicycle with drop-bar or shorter (not longer than 600mm) flat-bar is recommended to be loaded onto the door side holder. **

D.  Load the other bicycle BACKWARD (Front & Rear of the vehicle & bicycle are at the opposite direction.) onto the inner holder. (Below left) Tightly fasten the Fork holder knobs & buckle up the wheel strap as well.

E.  Check if the gaps between bicycles &/or vehicle are OK (around 1”). If any parts are too close to each other or any contacts between parts are found, move the Sub-bar slightly ‘Left’ or ‘Right’, as shown above right.

F.  If any contact still remains, move the location of Wheel holder or Fork holder of the Frame sets as shown below left. To do that, the following tools are required.

  • 2 * 14mm spanner(one should be open-ended) for adjusting Fork holder

  • 3mm hex wrench & 8mm spanner for adjusting Wheel holder

** To switch the Frame set from ‘left hand drive use’ to ‘right hand drive use’, detach & move the Wheel holders to the opposite side as shown above right. **

G.  If no further contacts are found, install stabilizers lastly. Adjust the length of the longer stabilizer properly by loosening the knob first. Install it between the inner bicycle & headrest of the 2nd row seat, as shown below left. Install the shorter stabilizer between bicycles as well as shown below right. And, check once more if the knobs of the stabilizers are securely fastened.

** As the stabilizers are ESSENTIAL to maximize the stability of bicycles to be carried, installing of stabilizers shouldn’t be skipped. **

H. To load a bicycle with 15mm Through-Axle fork, install the ’15mm Through-Axle adapter’ to the fork first (Below left, sold separately), then fix the adapter onto the fork holder. (Below right)

** Front wheels are recommended to be placed in the space (Leg room) between the 1st row seat-back and the 2nd row seat.

** When you carry just one bicycle, fasten the knobs of the Fork holder not in use and buckle up the wheel strap to minimize noises.
