i have a Tern that comes with what I call a centerstand As opposed to the sidestand of my Rize. Love the functionality of the centerstand. But it’s at a cost if you are riding any rough ground as you lose clearance. If you do no off-road riding, I would say it’s a wonderful addition and would be of big benefit dealing with flats/chain maintenance etc.
Belated reply. I'm using the Ursus Jumbo - for the past year now.
I did a write up on the whole installation in the R1U forums - here we are a year later and here's my current impressions:
A few photos. Look at the comparison of the common variety (I removed) and the Ursus (installed).
With a 12pack on the rack and another in the basket, or 80+lbs of Groceries, it never tips over even on lumpy grass.
Not like 'tube' type's that bend, are always crooked, work loose and the rubber feet just fall off - with no new ones available.
This baby sits perfect and when it folds upward the arms neatly tuck in from 18" open (down), to 7" closed (up).
The difference is, Jumbo's exceptionally robust cast alloy construction, mechanically sophisticated mechanism, beefy springs, thick steel plate housing, and insanely thick hard coating - not cheap paint easily scratched.
Jumbo's top clamp is much larger and the bottom clamping face has 3 x the area as the competition - with passages for most wires and cables. Even the rubber feet on the Jumbo are, quite 'Jumbo'.
For perspective, if the competition was a size 5 shoe, the Jumbo would be a size 25.

The bad:
1) Weight is 2.6lbs.
If you want chunky cast alloy is heavy. 2.5 x as heavy as flimsy tubing.
When the Jumbo is down, it's base spans 18" - twice the competition's - with zero flex. I had the competition's tubing simply bend and bike fall over, form a breeze. It never would stay even. The tubing was low grade. I destroyed three of them in a couple months.
2) It seems to rattle a bit on larger bumps.
My bike did the same before I installed the Jumbo. I remover stock kickstand, no rattle.
Installed Jumbo, same 'frequency' of rattle under same condition, but much more of a 'ka-clunk'.

Ursa has other high quality kickstands and V-stands. Here's their site

Highly recommended.
PS.
This Ltd is tight. Rattles worry me. Now that I've been reminded, I'm going to zip tie them on todays jaunt and be certain.
Thanks !!
