As long as you're buying a new lock Tundra Man, buy a decent one this time. I hear you on not having much of a need to lock there; my workplace rack is the same situation: right by a camera, security patrol, pretty deep onto private property... But it's every day. One day there will be a bold thief who sees he has a few minutes before security comes back and boom. Free bike.

How about a Kryptonite chain lock? (weight doesn't matter much, since it'll mostly live on that rack) I like those because they can be carried cross-shoulder if needed.

The commute this morning was TOUGH, even with the Yamaha Class 3 eBike. It was a 20-30 mph wind gusting to at least 40. I had the assist on STANDARD (only TURBO is higher) but was barely managing 12 mph into that wind. With no wind, it would have been an easy 25 mph ride on that stretch with that much assistance. It would've been AWFUL on a muggle bike.
