My diy steel-fullsuspension bike is completed

After about 3 months of testing, my bike is finally ready:
I used an old hardtail frame as a base and modifed the geometry, installed a bearing and made a rear swing.

Here is some data:

• Material: Frame from an old Giant bike, rear swing from steelpipes from a building supply store
• Costs: around 550 Euro, all parts were bought used in mint condition.
• Travel: 160/160mm
• Thrust in my own welding: I still check for cracks regulary
• Weight: 16 kg

Here are the links to the blogentries about how I built it:
