Just bought a RadRover Fat Bike. Fenders are out of stock until the end of the month but I thought the best first accessory might be a Bike Lock. Because of the frame shape I wonder if I will still be able to mount some form of a U-Lock on the bike? Where on the bike will it fit? Is this the best idea or do you have other thoughts?

Also, I see that rear bike racks are out of stock also until month end. RadPower comments that it's only been tested with their rack but I wonder if I am limited to their rack or will other third party racks fit the bike? For example, I am wondering about https://amzn.to/3dB1kpp for example?
