I'm sure folks have given a great deal of thought to this, but has anyone come up with a way to lock down his/her wheel? When I got it, I thought, oh, I can lock it with the app ... but that seems to me to leave the wheel on, which doesn't seem great for battery life, and of course, it doesn't stop someone from carrying it away. I think others have mentioned here that you could put a cable through the trolley handle bracket, and then of course someone could just unscrew the bracket, but at least you'd have some initial deterrence. Has anyone come up with anything else? I never thought I'd say this, but this issue might actually cause me to relinquish the wheel (after having worked so hard to learn to ride it!) and just ride a bike more often.
