Rotec is Back With a 5'' Travel Play Bike - Interbike 2017
Unlike the Revert, the Lawilll might actually pedal, despite having almost double the travel. The Revert is a fashion statement bike with a compromised functionality. Its great virtue is the rear end rigidity and I'm all for it, however it's also generally accepted that some give in the rear end improves traction. And a good VPP design is more rigid anyway.

Is This Linkage Fork the Future of Suspension? - Crankworx Whistler 2017
@Structure-Ryan: I'm thinking that the last part of the travel, even if it's just some milimeters, could be handled by a little elastomer or rubber piece somewhere between the two "head tubes". This way the maximum force the linkage and frame would be subjected to would be reduced, since at that point the force would go straight up to the stem and handlebar like on a regular fork.

Specialized Update Enduro for 2018 - First Look - Crankworx Whistler 2017
@Jetbenny: I took some measures from the photos and the actual drop at the shaft would be only around 21mm. However because of the added slant, the rear extremity of the seat, which is what gets in the way, goes down by 85mm. So 85+115mm=200mm, which is quite satisfactory...

2018 Devinci Spartan - First Look
36t chainring max is bullshit. It would be quite enough with a 10-42 or 11-42 cassette, but in the age of 46t and 50t cogs, chainrings can grow proportionally. I would run a 40t chainring with an Eagle cassette (but not with this bike, which I will never buy because of this 36t limitation.

Cannondale Jekyll 2 - Review
No mention of the pathetically small (30t) chainring and the rear pivot that's set to match it? So the higher you go from there chainring-wise, the worse the bike will pedal. So in comes the travel adjuster. I much prefer a bike that actually pedals good at any travel than one that pedals bad at long travel, and a little better, but still bad, at short travel.

Is Polygon's Square One EX9 the Elusive 'One Bike'? - Review
@WaterBear: The center of the arc made by the wheel's path is a little above the pivot that links the swingarm to the small linkage next to the slider. It could be described a somewhat high and forward virtual pivot position. Which sure gives better pedalling than the below chainline pivots that so many brands are favouring for the sake of less chaingrowth.

Marin Wolf Ridge: First Ride
I have just realized that, from reading the comments here. I had no idea that people were choosing bikes because of aesthetics. Actually, I have no idea what these aesthetic standards might be. It's just a factor that I never thougth about in the slightest.

Marin Wolf Ridge: First Ride
From my perspective as a bike designer, what matters is that it works. Lightness, rigidity, and the fulfillment of the various kinetic parameters. You don't set about creating a beautiful looking bike, whatever that might be. It's completely irrelevant, to the degree that the word has no meaning whatsoever, besides what concerns the fulfillment of the aforementioned parameters. What happens is actually the opposite. When a design works well, it becomes what people want and it becomes coveted and admired, namely aesthetically. For example, the Santa Cruz VP Free in my opinion, looks rather cumbersome, not aesthetically pleasing at all. Still, its suspension system has now become widely adopted by many brands. It's no longer hurting eyes because it has been proved to work.

Marin Wolf Ridge: First Ride
I usually hate black bikes and wouldn't say the polygon is a looker, but I like the looks of this Marin very much.
