Wow that’s very impressive.very hilly where I live can’t escape those steep gradients.
It's impossible to tell from a photo what your rear cassette is.
The front is 50-34, so lowest chainring 34. It's likely the rear is 32 or 34, though it could be 28. You need to count them to confirm.
I'd very much expect with any of that gearing your quads to hurt on a 10% hill after a year off. If you've got a 28, I'd recommend changing to a 34. You'll likely need a new derailleur (long cage variant) if that's the case, as well as the cassette.
A more substantial change to the drivetrain would be needed to get much lower gears.
Enjoy the ride!
