I'd been kicking this lock around for a while till I found a good use. In my area, all that is really needed is to thwart a thief from actually riding your sled away, is a stop to it from rolling away. Without wheels, there is no getaway! This is a quick solution using a VERY LARGE lock.
Step 1: Rubberize
I used an old inner tube to rubberize it and give it a little character.
Step 2: Lock it up
I grabbed 3 spokes and locked it around the rear drop out on the frame. Now you may enter the store for that desperately needed Choco Taco!
Step 3: Quick storage
I lock it to the handlebars for easy access and convenience. Also the main reason to rubberize.
Picture me rolling ;)
