Bike Locks?

<p>What style of bike lock is most effective and secure? What is the recommended style? </p>

<p>I currently have a thin number lock. It's one of those curlicue, plastic, stretchable ones. A mathematical genius-klepto or anybody with scissors can remove my current lock.</p>


<p>get a "u" lock.. the two ends of the u connect to a bar and lock into place. solid steel, nobody will cut it</p>
