Does motorcycle need to have metal rack to assemble saddlebags?

Basically our motorcycle bag has all designed for universal mounting system which does not need to have metal rack to install it. Our main concept is no screw, no drill hole for rider to attach and to detach easily without any special tool.
Please check our video on Youtube for further demonstration for Tank Bag, Saddle Bag, and Rear Bag.

Tank Bag System: There are basically three ways to attach the tank bag on the tank, such as the Magnet, Suction Pad, and the Straps. Our design is mainly using magnet and strap combination. Also there is a handle security strap for all the tank bag which is able to be used as a shoulder strap when the tank bag is off the motorcycle. Suction pad is main for “non-metal” tank to use.

Saddle Bag System: There is mainly having two wide straps at the center of the saddle bag. Both has male and female Velcro for attachment and also for adjustment for the length based on the width of the seat. The back of the saddle bag has two stable straps with buckle fasten on each bag which is important to use at least one strap to prevent the bag to hit the ground when the motorcycle turns.

Rear Bag System – Mainly it has two release buckle strap at the bottom to hold under the seat or the rack. And there are multiple buckle strap, at least four straps, to tighten the bag on the metal frame of the motorcycle. The attaching points will be the metal frame, foot rest bar, back passenger handle, or the back rack. Also there are multiple webbing loops or D rings for attachment. Rider can find the best way to fix the bag onto the motorcycle, as long as there are 3 points to tighten the bag, then it will be stable during movement.
