ACCESSORY 21: Combination bike lock $12 @ Target

I wanted something small and light enough to fit in the bag, so I was pretty much limited to a laminated cable. I try to bring as few things with me on my rides as possible, which means I don't carry keys. A combination style lock works perfectly for me.

With the weight of the trike around 43lb's combined with the alarm, there isn't much of a need to lock it anywhere too securely if I'm eating dinner with the trike in view. I just wrapped the combination cable lock around the back wheel to it's frame so no one would be able to ride it away. They'd have to swing by, hold me down and pop the trike into their pickup truck to take it. Let's hope that doesn't happen.
