The painner mounting must be light in weight, not cost much, easy to replace and easy to make.
The system is made out of kitchen plastic chopping board material (7 mm thick),
a little HDPE 1 m thick, some stainless steel 6 mm bolts, washers and nuts.
A 20mm square tube is used to make a frame that mounts to the bike.
Four sets of plastic 'teeth' are mounted per side of the frame, two at the top, and two at the bottom.
Each tooth mount to the frame with two countersunk 6 mm bolts.
On the left you see the rack, with 4 teeth exposed while to the rear a pannier is attached to the rack.
The rack rests on a pannier.
The rack mounts to the bike
The rack has a rear loop that bolts on providing an increase in fall strength.
It is not fixed to ease removal of the wheel and of the rack itself. It is not shown in these photos.
Two 'rails' are bolted to the pannier - one at the top the other at the bottom.
Each rail has 3 bolts (6 mm)that pass through a 1.6 mm aluminium panel, the pannier lid (5.8 mm thick aprox),
1 mm thick HDPE sheet about 260mm long and 30 (bottom) to 40 (top) mm wide,
20 mm square kitchen plastic chopping board material, a brass washer (provides running clearance),
a 20mm wide 260 mm long kitchen plastic chopping board material,
a 10mm by 12mm aluminium bar 250 mm long taped 6 mm to accept the bolts.
On the right is shown a pannier with a partially assembled rail at the top and a fully assembled rail at the bottom.
The pannier is mounted through the lid, so when opened hopefully the luggage remains set.
If this proves not to be good I can simply remount the rails onto the base and plug the lid holes with screws.
The pannier rails have slots that take the teeth of the motorcycle frame.
The pannier is lowered onto the teeth, one of which is higher than the others to guide the pannier onto
the rest of the teeth.
The pannier can be secured from rising off the teeth using a bungee from the pannier's lid to the motorcycle frame
- this also secures the lid from opening acccidentally.
Or some bolts through a longer tooth can stop the bags rising off.
Bag security on the bike can be had by using the padlocks, that secure the bag lid to the bag base, passing
a wire rope from one bags padlock to the other through the bikes frame.
The wire can also be passed through the rear wheel to secure the bike as well.
The type of wire rope can be of the same type used to secure motorcycles or bicycles.
The bicycles ones are lighter, smaller, less secure and cheaper.
I hope the primary failure mode of this system is that the teeth, mounted onto the frame, fail.
These would be easy to replace - light in weight, small in size and cheap.
