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
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.
