Topic of the day: how my folding bike was saved

When I was riding my Downtube folding bike the other day, the chain all of a sudden fell off. And the 2 pieces of the chain guard (one on each side of the chain ring) were not held together anymore. I had to push it all the way home. I took it off after I got home:

Without this piece, the piece on the other side of the ride would not stay on either.

After further examination, I found one link of the chain is broken too:


I almost wanted to give up because I thought it would cost me quite a lot to buy a new chain as well as replacing the chain guard. Fortunately I didn't. Turns out the whole "repair" costed $6! I bought a few nuts/bolts/washers to reattach the remaining half piece of the chain guard to the chain ring. And with the help of Performance Bicycle in Mountain View, that 1 broken link in the chain was replaced. Now it works again :D
