Frame lock for Rad Rover 6

[Rhino6Plus]

Hi,
Is there a frame lock that's wide enough for Rad Rover's wheels? So far the widest I could find is 92mm, which probably wouldn't fit the 4 inch tires.

I know that frame locks are less secure than e.g U locks, but I am mostly trying to optimize for the time it takes to lock and unlock, and I assume frame lock is the fastest.
Today I own a cable lock, and I get always annoyed with how long it takes me to pass it through the frame and the wheel...

Thanks!

There are mounting points on the seat stays that look like they are there for a frame lock but I have not been able to find one that would fit over the 4 inch tires and the fenders. I'm thinking the RR6+ frame was derived from another bike with narrower tires but I don't know if that is true or not.

I recently purchased the RAD fat tire wheel lock and the Rad wheel lock security chain that goes with it. The long one.
