How my quite large panniers was made

Many years ago, in 1996, me and my wife had too little money to afford a car. For a short time I had work in a mechanical work shop, and I there made a bicycle trailer to get food and other things home from the store. The trailer was also used after a very tuned Piaggio Ciao, even on long distance vacations.

The years went by, and me and my wife got better income. The trailer wasn´t used very much, most of the time stoved away in the garage. Then I got the Innova in may 2011 I didn´t use the trailer at all.

Then I got my Innova the I soon realised that I could use it for long distance driving. The first three years I used the cheapest soft panniers there was (40 euro) and two equally cheap waterproof sacks (14 euro a piece). I used those panniers and sacks during 28000 km with no problems at all.

Last winter I began to think about lockable more secure panniers, large enough for my use. I almost bought a pair of slightly crashed KTM Gobi panniers, but they was sold before I got to the seller. New big panniers was way out of my budget. I hade to make my own.

I got aluminium frame parts from old unused displays at the museum I then worked at. Made a few tests with those parts, and the result was too heavy. I did some experiments with corrugated plastic, but what wasn´t strong enough for big volume panniers. Then I remembered the trailer.

The trailer was 104 x 50 x 17 cm, which is 88,4 liter of volume. 44 liters of volume per pannier would be perfect for my needs. I cut the trailer apart at the middle, blind riveted on corrugated plastic backsides, made lids from 2,5 mm scrap aluminium sheeting och installed some excenter buckles. Detailing and sealing was an easy task.

But how to mount those huge things on a small Innova? The traditional way of hanging the panniers from the top wouldn´t work well at all. The only solution I could come up with was to make a frame at the bottom, standing the panniers on that and make support rods from the frame the up to the passenger handle. In that way I could use the brackets for the passenger footpegs, two holes in the passenger handle and two small struts at the upper front. I some times modify bicycle frames using brazing, and I also brazed the parts for the pannier frame.

The result have worked way better than expected. Sturdy, water proof and easy to use. Only 14 kilos in total, and each pannier can take my 80 kilos of weight when standing in it. I tested the sturdyness in the most brutal way by hitting a rock at the entry to the roman rock quarry in La Turbie, France. It almost made a hole trough the aluminium, but the mounts held up perfect.

I could write about the panniers in detail, but images says more.There is quite a few images, ´ll put them in new posts below this one.

The trailer I used as base for the panniers. TIG-welded and riveted aluminium construction:

Left side pannier ready for the details:

Starting work on the mounting frame. The bend in front is reinforced with a extra tube inside the main tube:

At the rear ends of the side tubes mounted in the passenger footpeg brackets there is M8 treads. Behind the wheel there is a bracket that bolts to the two side tubes. The rear bracket is slightly bent in the middle to make the alignment right with the panniers being placed narrower in the rear than in the front:

From the side tubes at the bottom there is vertical tubes up to the passenger handle. I made the lover end of that tube really strong. It´s reinforced with a extra tube on the inside. The upper side is bolted to the panniers with a M6 screw from inside, and a M4 screw at the top as extra security. I use a strap at the top, between the vertical tubes, to be safe if the top brackets fails in any way:

The final structural part is a small strut in the front of the panniers. I made a small bracket that bolts to the screw holding the plastic parts at the side of the Innova. That bracket is the only part of the panniers that I leave on the Innova then the panniers is not in place:

The panniers is mounted to the lower side tubes with brackets bolted to the bottom of the panniers:

Those bottom brackets has screws to lock them in place. That eliminates rattling sounds from the overlapping tubes. I worried a little about the lock screws loosening because all the weight acting on them, but the bracket tube is elastic enough to make proper preloaded screw joints:

This is how it looks from the rear:

I extended the wiring for the indicator lights, and made brackets for then on the panniers. A small aluminium angle and a front suspension part from an old radiocontrolled car looks quite nice, and the movable bracket makes it easier to store the panniers then not mounted to the Innova:

Minutes from driving south on the fourth of june last year. One waterproof sack to use for the cold weather clothes then not needed, a small bag for the things I doesn´t want to leave on the bike then going away from it and a Birchmeier Rapidon 6 fuel canister. The very nice Rapidon 6 makes for fast refueling, which makes up some time with a small fuel tank like on the Innova:

Home again 23/6. The silver tape on the front of the pannier is the only modification I had to made. At first, then testing the panniers, I was a little surprised then driving in sidewind. Then the wind hit the bike it first leaned over like normal, but almost directly it started to move over to the other side, leaning in to the wind. The cause is the angle of the panniers making aerodynamical lift. The tape broke the clean flow of the wind, and took away the aerodynamic effect:

Great job dude! winglets at the panniers of an innova, i see a brother in mind ;-)
My Innova surprises me nearly every day how easiyly it carries nearly every luggage. To keep it save and dry is a challenge you did in a great way.

I forgot the cost:

About 40 euro for the bolts and nuts, brazing rods and gas, and the blind rivets. The rest was things I got for free or found in dumpsters. When I made the trailer all whose years ago the owner of the work shop gave me the materials for free.
