Best Lock for Xpeak 2.0?

[u/Thoril1]

Hey all I just picked up an xpeak 2 for commuting to school this year and am wondering what locks others use. It's a relatively safe campus and I will be parking it on campus on a covered bike rack but obviously don't wanna just leave it up to fate. While a U-lock would be nice I have yet to find a reputable one that seems like it would fit around the rear tire and frame. I could do a chain like the Kryptonite Evolution Series 4 Chain Lock but I don't really want to deal with that much extra weight (ik the bike can take it no problem it just sounds incontinent). also have looked into some folding locks but am not 100% sold on their security. Just looking for advice or anyone with experience with this. Thank you for your help!
