I find the pedals to be too narrow.

I added a black traditional location kickstand, but will probably replace it with a rear-mounted one, as I find the center mount is no good with a load on the back.

I plan on upgrading the lighting to an Inolight Extreme at some point, but the standard lighting is fine for lit paths.

I went to a B33 seat, but that would be too heavy-duty of a seat for your weight. The suspension seatpost may work for you with your light weight. At 100Lbs heavier than you though, it was no good for me, so I went to a solid seatpost.

I've not had any flats yet. If I start, I'll probably switch to Schwalbe Marathon Plus tires.

I do love my bike.
