When shopping for :

Bikes, Light = better

Locks, Heavy = better

"You get what you pay for" still applies to everything ! Any questions ?

... and don't "lock-up" in the same spot every time ... soooo... don't leave the lock there !
What will you do : if when you get to your lock, it has a piece of bubble gum in the lock core, or super glue, or it has been removed ???

I think Kryptonite would like you to spend 10% of the price of the bike on a u-lock.

Some also use a mathematical formula : bike + lock (must)= 30 lbs !

A 29lbs dept. store next/huffy/etc. only needs a combination cable lock, the size of a shoe lace.

An *ok* road bike, that cost over a grand and under 20lbs, better get the ney york chain, thats 9 lbs.

Your fancy new carbon steed thats under the UCI limit (15lbs), better get a boat anchor, or better yet dont lock it up !
