Last semester I lent my bike out to my roommates friend for 2 days (I know, bad Idea). He returned everything, but the ulock key, and mini pump. Oh yeah I forgot to mention that he left the ulock locked on my bike frame. Long story short, he never returned the stuff, so I began to look for a new lock.
I browsed online and read that chain locks provided some of the best security, but i found them to be quite spendy ($20-65, yes $20 is spendy, I'm in college :P). So I sought out to make my own chain-lock for cheap!
This build is so easy it's pretty ridiculous and should cost you less than $12. Let's get to it!
Step 1: Getting the Right Chain
I don't recall the exact specs of the chain I bought, but it was about $3 per foot. I got 2 feet which Is enough to at least lock the frame to a post. I think 3ft or 4ft would be ideal. You can make it as long as you want within your budget, just keept in mind you have to lug it around.
On to step 2!
