The 58cm/XL frame with a 20mm - 30mm shorter stem than OEM has always worked for me (5'10"). I simply like the look of a bigger bike. Yes, I am a size queen <snap> <snap> <swish> ...

That, or they know their market. Maybe they're targeting people whose taste for the simplicity of coaster-brake bikes extends to being happy with bikes that are almost as limited in sizing as the one-size-fits-all balloon-tire coaster-brake cruisers of the '30's, '40's, and '50's.

The great thing about simple flat-bar bikes from the point of view of bike companies is that sizing is less critical than for drop-bar bikes.

It'd be weird for them to make only three sizes and the large is only for people 6 ft and over. But that's what their website says. That's not a lot of the bell curve. It's like 20% of men and nearly no women.

What limited geo they list seems strangely chosen.

OP, For lack of really specific bike geo information or the usual five sizes, I'd instead ask - do you feel like you're a tall person? Then get the L

Strangely the Priority 600ADX and 600HXT come in XL, it's only the 600 that does not. Maybe they think the straight up commuter is a woman's bike and men will buy the more manly adventure versions. I dont need the squishy stuff as I will only be on pavement.

600HXT and 600 ADX

inseam goes 1.5" longer than 600

Medium: Inseam 29" - 33"
Large: Inseam 31" - 35"
XL: Inseam 32.5" - 36.5

If one is truly between sizes (not just they think they are) my recommendation is size down for performance, size up for utility or casual use.The type of bike also comes into play.

According to internet searches the 600 used to be available in an XL presumably with similar sizing as the XL size of the 600HXT and 600ADX. No mention on why only the adventure versions of the 600 now have the XL option. The 600 ADX, even with the squishy front end, weighs about the same and keeps the upright geometry. This seems like a safer bet in L and may even be more fun to ride.

If you look at the bikes, it's clear that those models are not different version of the same bike -- they are completely different frames. The only commonality is the "600" in their names.

The 600ADX is not overly dissimilar to the 600, it shares many of the same components and the upright riding geometry. The squishy fork is the primary differentiator.

Priority states, "The 600ADX delivers more sizing flexibility for riders - both across a range of heights and within a sizing tier. The geometry remains comfortable.”

The 600ADX puts me in the middle of the L range instead of on the fringe

It’s the 600HXT that goes for a more aggressive geometry and uses a e-version of the Pinion

Anyone can look at those two bikes and see that they use very different frames. Seriously, open your eyes and utilize some grey matter.

Yes frames are configured differently. I agree. But Priority positions it as an option for someone needing more height options than the 600 offers and claims a similar upright seating position. It seems to be more the HXT that breaks the 600. mold

The Specialized Sirrus also has two distinct frames but their riding characteristics are similar.

i have contacted Priority about swapping out the squishy fork for rigid on the ATX. I don’t mind spending the money. A Pinion build here is north of 8k CAD

Why are you obsessed with the idea that two different bikes, based on different frames, aren't offered in the same number of sizes? This happens all the time. There is nothing to understand -- it is simply a fact of life.

Because Priority emphasizes its similarity to the 600 in terms of riding position and offers it as a good option for those seeking more sizing flexibility.

So basically it sounds like the bike I want except for the squishy fork which I assume can easily be swapped for rigid after purchase.

No.

The common denominator between the 600 and the 600ADX / 600HXT is the 600% gear range they get from the pinion setup. Beyond that, they are very different bikes -- the 600 is a commuter bike, while the other two are hardtail mountain bikes. They are offered in different sizes, as is common with different types of bikes. That's it. Finito. End of story.

And yet Priority emphasizes the similar riding position and says this, "The 600ADX delivers more sizing flexibility for riders - both across a range of heights and within a sizing tier. The geometry remains comfortable.”.

Priority has purposely built a correlation between the 600 and 600ADX and since the 600ADX sizing goes larger than the 600 it can be reasonably assumed that the goal is to lure men to a more "adventurous" commuter. A quick search reveals that many men have purchased the 600ADX as a commuter/light trail bike.

The 600HXT breaks from this correlation as Priority emphasizes a more "aggressive" geometry and does not mention the increase in sizing options.

From a marketing perspective and geometry implementation, Priority has positioned the three bikes as a progression.

I don't believe this is their intent, and I can scarcely believe that you even wrote this.

On second thought, I can believe that you wrote this.

No, it is not reasonable to assume any of this. The "correlation" you think you see is restricted to the names all containing "600".

Well marketing claims it’s true, it must be true.

Then again, I’m reminded of what Lincoln once said.

So the question remains, assuming their claim of a similar riding position is accurate, then exactly what difference, besides the squishy fork, can I expect?

The sizing of the ADX appears much more suitable as I am positioned in the middle of L and not on the fringes of M and L

1. Ride a commuter bike
2. Ride a hardtail mountain bike.
3. Note the difference.
4. Pick the one you like and buy it.

I rode a NORCO hybrid/squishy fork bike as a commuter for years.

The 600 HXT claims a "more aggressive" position and is marketed as a Mountain bike (more sizing options)

The 600 ADX has a "comfortable upright" position and is marketed as a Bikepacking bike (more sizing options)

The 600 has a "comfortable upright" position and is marketed as a Commuter bike (less sizing options)

I replace the squishy fork with rigid on the ADX, what would you suppose the differences to be?

With these bikes ranging in price from $2499 to $3499 I would drive a couple of hundred miles to NY and test ride them before committing. But, maybe money is not important here.

Yes I plan to detour to NYC, about 7hrs from my location.

My understanding is that NYC is where their office/administrative center is located so they may not have all bikes available for testing. The warehouse is in PA. I would gladly visit there as well but it does not appear to be an option.

But that would negate the need for this thread, so how would that help him?

Do the tour. I bet they would fit you while their. Could even just buy the bike there I bet. In the Duzer videos with them they sound accommodating.

Keep in mind that sizes are not standardized and companies can call them whatever they want. For that reason, viewing the geometry chart is more useful than guessing based on some arbitrary label. Centimeters are centimeters (or if you prefer, inches are inches). Looks like Priority doesn't list stack and reach, but you can likely figure out what you need to know based on what they do show.
