Plug-in Bike Stand for Xpedo Pedals (Face Off)

Featured
Picture of Plug-in Bike Stand for Xpedo Pedals (Face Off)
0. I have a bike with Xpedo pedals, and no kickstand
1. I would rather have my bike stand while I go buy some satay, but I didn't want a stand attached permanently to the bike
2. I also have lots of aluminium tubes left over from other projects

Bike stand must be light, easily carried in a backpack next to my lock, easily attached and removed,

Step 1: Material and Measurements

Picture of Material and Measurements
I am using 16mm OD aluminium tubes. The ID can be between 10 to 12mm. You need two measurements from your pedal; the width, and depth. My Face Off pedals are about 80mm in depth and height. You will also need to measure the distance between the edge of the pedal and the ground when your bike is at a stable resting position. For my bike, it's about 10cm.

Cut and mark your tube. For my pedal/bike, the measurements are 75mm, 100mm, 80mm, 100mm and 75mm (pedal depth, distance to ground, pedal width, distance to ground, pedal depth)

You should file down any shape edges right after cutting. You don't want sharp edges later when you start bending the tube.

Step 2: Flattening the tube

In order to bend the tube, I am flattening the pipe in certain places to accommodate the bend, and also to insert the stand into the pedal. The Xpedo pedal clearance is between 10 and 7mm. The flattened parts of my stand is 6 - 7mm.

Start by bending the middle part. You need to fatten the middle part, but extend the flattened portion about 10mm beyond the bending point. This helps you bend it easier without snapping off the tube.

Step 3: The Middle Bend

I start by clamping down the flattened portion, with the vise edge at the bend mark. This allows me to bend usually about 45 degrees before the tube snaps.

Release the stand at 45 degrees, push the tube forward by about 5mm (which is why I allowed a 10mm distance when flattening earlier), and bend further.

Important points about bending tubes:

1. SLOWLY
2. Use body weight; lean
3. Avoid sharp edges (hence, the filing earlier)
4. Wear gloves
That is a nice elegant solution. In general, how stable is it been with use?

Thanks for your comment! It has been holding up my bike when it is stored at home, or in the fields when we go out camping. It is surprisingly stable because the base, being "square", resists torsional** forces*. As long as you place it with the crank just a little back from the vertical, it will stay that way for a long time :-)

* it's like the _support_ (read: stand) being a box instead of a circle. The circle would have been fine, until it is moved a little.
** i am sure this can be more accurately described; i am neither a mathematician nor a good/recent student of physics :-)
