HiShark413,
It's good to see that you enjoy yer ebike toyz much in the same way that I enjoy/appreciate my own herd of beasties.. I noticed this thread of yours and thought I'd add some possible options for you to consider. The following two options need to be combined to make everything work as intended.
[[First of all, you might want to scroll down to the end of this response and view the photo's prior to reading this info.]]
Option#1: Instead of dealing with having to swap out an entire right-side crank arm set (crank arm, chain ring, and pedal) whenever the need/desire arises, just install this item at the rear wheel axle location:

Since the XP Lite is a one-speed, you don't have to be concerned with shifting/running a wire cable/use of a gear changer. What you do want is the ability of the above-shown mechanism to keep tension on the chain via the 2 little wheels and the arm unit.
And why is that? Because of Option #2.
Option#2: The photo's of your 42t crank arm and your 52t crank arm show me that you can very easily convert the 42t unit into a 42t AND 52t(or higher) crank set-up. That's right a double chain ring set-up-- just like on an old school roadie bike.
You will notice that your 42t unit has 5 hex screws holding the ring AND the chain guards (the 2 toothless disc's-- one on either side of the 42t ring). Those are actually chain rings, too. It's just that they don't have teeth.
Since your pictured 52t chain ring is not usable, what you need to do is purchase this 53t item:
https://www.amazon.com/dp/B07CRY4ZH7/ref=sspa_dk_detail_1?
You can then replace the outside smooth chain ring guard thingie with the 53t chain ring. Plus, it even has an included guard. You now have a 42t/53t double chain ring crank arm.
You may now be wondering about Option #1.. Simple. It will allow tension to be maintained on the chain itself. Whenever you want to go from 42t to 53t (or vice versa), just halt the XP Lite mighty beastie..Dis-mount.. Grab the chain.. Manually move it to the appropriate chain ring.. Eazy Peazy.. Takes about 10 seconds total..
The rear derailleur will assure that proper tension is kept on the chain itself at all times.
By the way, be sure to use the 42t chain ring to determine proper chain length (in case you need to add/ remove links). To have “chain sag” while on the 42t setting is a no-no. It needs to be “tense”, too.
In case you do need to do chain link modifications, you might consider these items: I use them on all my bikes. They also give a quick reference to a starting/ending point during the monthly lubrication of my chain(s).

So, there you have it. Hope my input helps you out.
By the way, I actually use the multiple chain ring set-up on 4 of my ebikes (they are all multi-speed beasts with a rear derailleur). Itis usually a 47t/58t combo, or a 44t/56t combo. And, just as I advised you: I stop, dismount, grab the chain, move it to the other chain ring. Takes about 10 seconds total. Yes, I am, in reality, a
manual front derailleur.
In my case, it's usually more about using different color combos for pedals/crank arm/ large chain ring/ smaller chain ring. I have more than a dozen different color combo's. I just pull off the crank arm and replace the entire assembly at the same time. Too much fun.
While perusing the LECTRIC forum, I noticed another poster asking about water bottle holder information. I have a rather novel option for that/those item(s), too. I'm gonna go ahead and post a response tohis question, too.
