You can use hitch bike racks. This type of rack can be mounted on the trailer hitch of the vehicle. It is also easy to install and has one of the most popular racks that you can use. Hitch bike racks are also easier for the biker to put and remove the bike compared to the other bike racks.

If your bike happens to have a bike rack, then you can put the u-lock in it. I know some companies who are designing bike rack that enables the u-lock system to fit in perfectly. The rack has a wide opening that was made so that the u-lock can fit nicely into the bike rack. I am not sure if it is intentional or not but I was amazed by the design and how it perfectly fits the u-lock system.

You can consider a Rhinowalk top tube bag. With easy to open design; it gives instant access to all the things inside. It provides enough storage space for small items and will give enough stability once installed in the bike's top tube.

A nice alternative is the Oranlife bike handlebar bag. I like to use my phone as a GPS device when cycling. It works great when it starts to rain. It protects my phone from the elements and keeps it dry. The storage space is adequate, and I am satisfied with my phone holder in general.

This SGODDE seat cushion is very thick but surprisingly soft. I can even press the cushion through my fingers. Although it feels very soft and thick, it remains its form and shape when it is not in use. It eliminates the pain which I always feel when using the stock bike seat. This seat is suitable and comfortable for both myself (male, 220 lb) and my wife (female, 145 lbs).

You can consider Abus lock. This cafe bike lock is convenient to use because it does not need a pole or rack while attaching your bike permanently. Also, locking in itself means it will stop the rear wheel from turning, which means it will be impossible for the theft to jump on your bike and steal it away from you.

I use an ABUS chain lock, made with hardened steel to provide high-security features. In terms of security, this chain is most formidable in providing maximum protection for the bike.

Those chains look ideal for leaving in place at the lockup location, but heavy to tote around (I've seen people wear them like heavy belts).  I use an ABUS U-lock, with an ABUS cable for additional options (locking two bikes, looping through front wheel, locking to a tree etc.).  Found a nifty location to strap it to the rear basket of my Mini StepThru with the ABUS mount after much pondering on that unique frame.  The cable is coiled and the two end loops passed through the U-lock to secure it in place.

I agree with you that ABUS u-lock is a great option.
